Adaptive Servo-Ventilation In Sleep Apnea Treatment

Adaptive servo ventilation explained - blog post cpapeuropa

What is Adaptive Servo-Ventilation?

If you have sleep apnea, you might have heard about adaptive servo-ventilation. What is adaptive servo-ventilation (ASV), though? And how is it used to treat sleep apnea? Today we will answer these question and dive further into the topic of ASV and its implementation in sleep apnea therapy.

Adaptive Servo-Ventilation (ASV) is a type of non-invasive ventilation used to treat patients with central sleep apnea. ASV is also used to treat patients with mixed and complex sleep apnea as well as Cheyne-Stokes. As a central sleep apnea treatment method, ASV dates back to 1998, when it was introduced as a method to treat the condition while continuously monitoring the patient’s breathing pattern.

Sleep apnea is one of the most debilitating modern day sleep disorders. ASV has been widely utilized in treating patients with the central type.

The main pros of adaptive servo-ventilation

Adaptive Servo-Ventilation comes with several pros when applied in the treatment of central sleep apnea. In addition, an ASV device is especially beneficial to patients with complex sleep apneа mainly because of its capability to deliver variable flow upon demand. ASV sleep apnea machines are also used to treat obstructive sleep apneas as well.

Compared to standard PAP devices, ASV machines auto adjust to respond to the sleeper’s changing breathing patterns in the events of central sleep apneas. This helps patients to breathe easier throughout the night and ensure that they are getting an adequate supply of oxygen during therapy.


ASV Device Example:

ResMed Aircurve 10 ASV with Heated Humidifier


Cons of adaptive servo-ventilation

ASV therapy may not be the most suitable choice of treatment for some patients with symptomatic heart failure. That’s why adaptive servo-ventilation therapy must always be prescribed after proper testing and diagnosis of the particular type of sleep apnea and patient.

ASV treatment is not recommended for patients with the following health conditions:

  • Chronic hypoventilation;
  • Moderate to severe chronic COPD;
  • Restrictive thoracic disease;
  • Neuromuscular disease;
  • Chronically elevated partial pressure of carbon dioxide (PCO2);
  • Arterial blood gas greater than 45 mm Hg.

CPAPs with ASV Modes

Adaptive servo-ventilation is a form of positive airway pressure therapy (PAP). The method automatically adjusts the delivery of air pressure to the patient according to how many pauses in the breathing are detected during sleep.

Sleep apnea devices (CPAP and BiPAP) with ASV modes rely on complex computer algorithms to adjust the pressure throughout the therapy cycle. In that regard, adaptive servo-ventilation “starts” the patient’s breathing only when required. These sleep apnea devices use the same accessories (tubes, masks) as standard non-ASV units.

What differentiates ASV in central sleep apnea treatment–as compared to standard OSA treatment–is its ability to quickly stabilize the breathing pattern and control arterial blood gases. ASV treatment is also more efficient at reducing patient discomfort caused by BiLevel sleep apnea therapy, while delivering the same personalized ventilation.

CPAP and BiPAP Treatment vs ASV

Along with adaptive servo-ventilation, there are two other widely used treatments for sleep apnea: CPAP and BiPAP therapy. These are the most often prescribed treatments for OSA, because they work and actually help the sleep apnea suffer to not only better their nighttime sleep but also completely eliminate the symptoms and improve their general health.

CPAP provides a single continuous pressure therapy while BiPAP provides two separate pressures upon inhalation and exhalation. ASV auto adjustment the pressure setting, and there is no pre-set number of pressures used in addressing central sleep apnea.

CPAP treatment is usually the first treatment prescribed for sleep apnea, then BiPAP. ASV may be considered next if the other treatments don’t prove as effective as usual.

It is of the utmost importance to consult a doctor if you suffer from sleep apnea and require treatment! The decision whether to put you on CPAP, BiPAP or ASV treatment is entirely up to your doctor and proper diagnosis.

What Is Polysomnography (PSG) and How Is It Used to Diagnose Osa?

Polysomnography (also called a sleep study test) is the main and most accurate sleep apnea test to date, capable of detecting different types of sleep disorders in just one night. This type of sleep test is one of the most complex tests in modern sleep medicine, although for the patient being tested the test itself is conducted without any inconvenience or complications.

Being a sleep study, polysomnographic testing is capable of identifying almost all types of sleep disorders the patient might have. Hence it is often considered the gold standard in somnology as it provides a clear picture on what the patient is experiencing during sleep – for example snoring, apnoeas, REM-bahavioral disorder or narcolepsy – one of the most serious sleep disorders.

How is polysomnography performed?

The test is conducted in a clinical settings environment, with the patient staying for night at place while being monitored by a sleep specialist who monitors his therapy on a screen all night. All abnormal activities are hence recorded and anaylised in real time. In the morning, the doctor (somnologist) analyses the data again and provides details to the patient.

What can polysomnography (PSG) detect?

As a multi-parametric sleep study, PSG detects the following:L

  • Brain activity (electroencephalogram – EEG);
  • Rapid eye movement (electrooculogram – EOG);
  • Abnormal muscle electrical activity (electromyogram – EMG);
  • Cardiac activity (electrocardiogram – ECG);
  • Oxygen saturation and pulse (pulse oximetry);
  • Lower limb movement;
  • Body position;
  • Respiratory effort;
  • Respiratory flow;
  • Snoring.

Sleep apnea (both obstructive and central types) can be easily detected during polysomnography testing. The screening picks up the physiological signals and apneic events during the night through special screening equipment attached to the sleeper. In addition to that, the polysomnographic testing is aided by video surveillance using a night vision camera tracking the sleeper.

Typical polysomnographic diagnostic tools for sleep monitoring

Polysomnographic examination is conducted when it is convenient for the patient and they are ready to be spend a night in the sleep clinic, where they will spend the night during the test. Patients are allowed to bring their personal pillow from home. Preparations for the test are minor and may include:

  • Cleaning and properly drying the hair of the patient;
  • Removing any acrylic nails and polish from the index fingers;
  • Avoiding afternoon naps in the day of the study;
  • Maintaining the normal diet to avoid influencing the sleep pattern and results of the test;
  • Taking the usual daily medications if there are any.

Polysomnography is a completely painless and non-invasive procedure that does not hold any serious risks for the patient. The only inconvenience is that you don’t get to spend the night in your own bed and that some skin irritation may occur because of the sensors attached to your body during the test.


Polysomnography is one of the most valuable studies in sleep medicine, giving the most comprehensive and objective multi-parametric test measuring both the quantity and quality of sleep of the examined patient. This modern day sleep diagnostic tool allows the doctors to pinpoint with uttermost precision when each sleep phase of sleep begins and ends.

In addition, polysomnography allows the identification of almost all sleep diseases, and is therefore considered the “gold standard” in somnology. It can be used to determine if the patient is snoring, gnashing his teeth, if he has sleep apnea, if he has narcolepsy, or some kind of parasomnia – sleepwalking, REM-behavioral disorder, etc., whether there are periodic movements of the lower legs. limbs or other unusual activities while sleeping.

Why to Replace CPAP Mask Parts On a Regular Basis

Why to Replace CPAP Mask Parts On a Regular Basis

Why to replace CPAP mask parts on a regular basis

Did you know that even if you’re using your CPAP machine every night, you might not be getting the most out of your sleep apnea therapy? Without proper cleaning and scheduled replacement of your CPAP mask parts, you will not be getting optimal results, which would instantly affect your daily life. Here are the top three reasons you should be regularly replacing your CPAP supplies.

CPAP mask parts are integral component of your therapy. Think of them like the important parts of your car – they must maintained in optimal condition for the vehicle to run safely. The same holds true for your CPAP mask parts, that is, if you want your sleep apnea therapy to run smoothly and not be compromised from a worn down or defective component, you’d want those cushions, headgear, tubes and frames to be in top condition.

Here are to main reasons to replace your CPAP mask parts regularly

If your mask parts are worn down, they will immediately affect your masks performance, which would definitely impact your night’s sleep. A recent Resmed study 1 showed that 70% of sleep apnea sufferers who replaced their mask parts reported a significant improvement in the quality of sleep. Those who did not do so and waited a year before replacing the most important parts of their masks, reported sleeping half an hour less every single night. This deprivation ceased immediately upon replacement, says the study.

Getting better sleep

Getting better sleep (elusive during the times before you started your CPAP therapy) comes with a range of daytime perks you should not be missing on,  especially because of a worn down or malfunctioning mask part that has been holding your zzz time back. By simply improving your quality of sleep you would be getting more energy during the day, allowing you to exercise more, better concentrate and improve your overall health by a significant margin.

“Every minute of extra sleep matters, and a worn down mask part can reduce that by up to 30 minutes!” – Gregory Bertrand, CPAPEUROPA.COM

Higher quality of life and guaranteed comfort

People who replace their CPAP mask parts as instructed by their sleep therapist, start to notice more energy during the day, not to mention improved comfort during the night. In short – you sleep longer and better; and your significant other also appreciates that fact. Getting out of bed fully rested and energized pays off in terms of a more satisfied life, better performance at work, and better relationship with your significant other.

Why sleep apnea sufferers sometimes do not replace their gear

The main reason of procrastinating to replace a CPAP mask part (even if it is worn down or broken) is attributed to several popular reasons. First and foremost, is the cost of replacement. CPAP masks are not cheap and neither are their parts. The important thing to understand here, though, is that these parts are vital for effective sleep apnea therapy – just like a new brake pad or rotor is vital for braking properly and not risking your life. The cost of CPAP masks can be significantly reduced if you have a trusted CPAP supplier that offers your needed mask parts at discounted prices. This way you can afford to regularly replace your mask gear without breaking the bank.

Other reason for not replacing your CPAP mask parts when they should be replaced are:

  • You don’t think it is necessaryAbout 30% of the people surveyed think that their CPAP mask parts last longer than what the manual tells them. They often don’t take into account how many hours they sleep with the mask, how they maintain it clean (what products or chemical they use to clean it), as well as many other external factors playing vital role in the everyday exploitation of the mask. No matter what these are, one thing is for sure — the mask parts, just like other things, will deteriorate as time goes. Oil from your face will also wear down the mask just like the necessity to clean it every morning. The frame can eventually crack and tear, the filters will eventually become clogged and stop filtering, the cushion will start to leak, etc. That’s why it is so important to not procrastinate and replace these parts as soon as you notice a visible sign of deterioration;
  • You forgetAround 10% of the people surveyed say they forget to change their parts regularly. That’s why if you notice a deterioration, make sure to set a reminder to replace the part as soon as possible. Your significant other can also keep track scheduled replacements and remind you when the time comes to do so.

Boris Johnson returns to Downing Street to lead Coronavirus response

Boris Johnson returns to Downing Street to lead Coronavirus response

Boris Johnson returns to Downing Street to lead Coronavirus response

British Prime Minister Boris Johnson is back to Downing Street to take charge of the response to the coronavirus outbreak.

Mr Johnson is to chair the regular morning cabinet meeting on the Coronavirus pandemic and later talk to government officials and ministers.

The Prime minister entered No 10 on Sunday evening after Tory MPs began pressuring him to lift the lockdown.


Is this the time to ease up?

Health Minister Edward Argar announced that, accordding to him, “now is not the time to ease up” despite the growing discontent voiced from the British public.

According to the latest date, the official figures of Coronavirus deaths in UK hospitals is 20,732.

Is Boris Johnson fully recovered?

One month after Mr Johnson was told he had COVID-19 and a week in St Thomas’ Hospital, the Prime Minister is back to Downing Street to resume his full-time duties and meet with senior ministers.

It is still uncertain whether Mr Johnson will lead the press briefing scheduled for Monday, but would be undoubtedly impressive to see him do so after recovering from COVID-19 and spending three days in intensive care.


In other news:

Elon Musk says he sent ventilators to California hospitals, they say they got CPAP and BiPAP machines instead

“We received six CPAPs and we are very grateful for the gift,” said a spokesperson for Sonoma Valley Hospital. Another Californian hospital Mammoth Hospital also said it received 10 bilevel machines from Tesla. “They’re not full ventilators but there are lots of people that need breathing assistance,” a spokesperson said, calling the donation “very gracious.”

Los Angeles County officials said they received from Tesla 100 bilevel units manufactured by ResMed in late March. The Resmed devices have been donated to US hospitals and are being used as intended. These units are used for breathing and airway support, reducing the need for certain patients to be placed on mechanical ventilation.

To ease or not to ease?

Whether to ease to lockdown or to extend it is a question the public expects answered without further delay, most likely in the next few days.

Limits on daily life were enforced on 23 March, with the public asked to stay at home, businesses asked to temporarily shut down and people asked to avoid  gatherings of more than 2 at time.

Currently, all ministers are obligated by law to make assessments on whether the strict rules are having the desired effect every three weeks. Next Thursday (7 May) the next evaluation will take place.

Social distancing across the UK

The current social distancing measures have caused the frustration of a large number of UK citizens, many of whom are wondering when the lockdown will end. Supermarkets have remained open as long as social distancing inside are followed.

Avoiding the second wave is top priority

China has already expecting a second wave of the pandemic as Beijing takes steps to stop a recurrence of the first COVID-19 wave. The most important decision of Mr Johnson and his team is how and when to gradually remove the lockdown announced on 23 March.

The ease off of restrictions needs to happen due to the severe economic harm and the massive strain on the NHS to handle the outbreak.

Many fear that a second COVID-19 wave would be far more deadly than the first one which makes the decision when and how to lift the lockdown a crucial point in the current situation.

Frances O’Grady, head of the umbrella group for unions the Trades Union Congress (TUC), expressed his opinion that social distancing must continue even when the lockdown is no more. Mr O’Grady also said that risk assessments in every workplace and safe transport should also remain present whether or not lockdown continues or nor.

Foreign Secretary Dominic Raab said on Sunday that social distancing would remain for “some time” in the UK and that restoring the normal way of life cannot be prolonged for too long.

What happens around the world?

Meanwhile, countries like Belgium, Germany and Denmark have expressed their intention of partially re-opening some businesses and schools.

Professor Stephen Powis, the NHS England medical director, shared during the daily No 10 briefing that: “My fear is that those curves won’t continue to be on a downward trend, but will start to go on an upward trend. We are not at a point where any of us can be absolutely confident that that’s not going to be the case.”

Meanwhile, Mr Raab insisted the government continue to fulfil is daily target of coronavirus 100,000 tests.

The end of lockdown will be decided by tests

Priti Patel has said that removing the coronavirus restrictions across the country will not be a binary choice and that the government would not give a date for the end of lockdown. The home secretary added that five tests will have to be met before schools can reopen but said giving a date ‘would be irresponsible and get hopes up’

Camping With CPAP: How To Do It Properly

Camping whit sleep apnea blog post CPAPEuropa

If you are considering packing your CPAP for a trip to the great outdoors, do not be discouraged – it can be done.

Although it may seem like a difficult task, camping with a CPAP is really not that challenging.

Sure, your tent is not the comfy bed you have at home, and, sure, there are no naturally occurring sockets out there in the wild.

But that doesn’t mean that you’ll be left stranded with your sleep apnea out there.

On the contrary, there is a convenient solution for treating obstructive sleep apnea in the wild. In fact, there are several.

Camping with CPAP is all about the right planning

To be properly prepared for camping on CPAP therapy, follow these easy pre-trip steps:


Step 1: Pack your CPAP / BPAP machine. If it is a travel CPAP and it came with a carry bag, use it accordingly for the purpose. Travel CPAPs are light and compact, so they won’t add that much of extra weight to your camping gear.

Step 2: Pack you CPAP supplies. Pack your CPAP mask (with all necessary headgear, with all the hoses and tubing.

Step 3: Power up your CPAP. Be sure to charge your CPAP’s batterires (travel models) and pack a spare battery if you have one. You don’t want your sleep apnea savior to run out of power in the middle of the night. Calculate how long each battery is going to last while powering your CPAP.


Buy Travel CPAP Machines

What if you don’t have extra batteries for your CPAP camping trip

The vast majority of CPAP brands offer portable DC power adapters capable of charging your device directly from the cigarette lighter.

Portable battery kits


If you haven’t extra batteries for your CPAP device, a practical solution is to use a portable battery kit that can charge a CPAP battery directly from your car.

Use a 12-volt car battery to charge your CPAP. In order to do so you’ll need a compatible CPAP 12 Volt DC battery cable adapter.

ResMed AirMini travel CPAP

The complete camping solution: Resmed Airmini

The Resmed Airmini is the world’s smallest CPAP machine — so small it actually fits in the palm of your hand! And, the Airmini portable CPAP weighsin at only 10.6 ounces. Small, light and yet as powerful as a full blown CPAP.

It is deliberately designed as a solution for traveling while on sleep apnea therapy – be it camping, plane travel or an epic road trip across the country. The Airmini will be there beside you.


Buy ResMed AirMini Auto Travel CPAP Machine

A mini CPAP as powerful as a full-blown device

The Airmini may look tiny, but make no mistake – it packs a powerful punch when it comes to efficiency. In fact, this travel CPAP provides the same features as the best-selling ResMed AirSense 10 Auto CPAP, including auto ramp, SmartStart, Bluetooth connectivity, and advanced expiratory pressure relief.

And, it comes with Resmed’s innovative waterless humidification system, which is another great plus when going camping with a CPAP device.


Transcend Auto Travel CPAP

Transcend Auto Travel CPAP.

Another great and more affordable option for camping with sleep apnea is the Transcend Auto Travel CPAP device. Just like the Resmed Airmini, the Transcend Auto is small, light and quiet, making it the perfect companion to take when travelling.

In fact, the Transcend Auto is a pioneer in the travel CPAP category when it comes to overall efficiency and affordability.

The Transcend Auto CPAP is a compact and ultra light portable machine designed for travel enthusiasts and patients leading an active lifestyle. This widely popular automatic CPAP device comes with the Transcend’s air bearing blower technology (EZEX) for quiet and vibration free operation.

If you’re looking for big features packed in a stunningly small package, then look no further than this premium mini device from Transcend.

Sleep apnea shouldn’t be keeping you from camping!

Spending time outdoors does not mean that you have to leave your comfort zone or make compromises when it comes to your CPAP therapy.

In fact, obstructive sleep apnea should nit disuade you from camping with your family or sleeping under the stars.

CPAP Europa’s line of portable sleep apnea equipment will make it possible to go camping, while maintaining the same therapy effectiveness that you enjoy using your home CPAP.

A travel CPAP device like the Resmed Airmini is specifically engineered to take care of that.

What if you stop your sleep apnea therapy for several days?

While it may sound like a good idea to just head out in the wild camping without taking any CPAP equipment with you, it is actually a terrible idea.

Pausing your therapy comes with many negative physical and mental effects as OSA’s debilitating symptoms will reoccur almost immediately.

Why risk backpedaling on your effective treatment and experiencing OSA’s symtpoms on your trip when the solution for camping with a CPAP is right here?

What You Should Know About CPAP Nasal Masks

What you should know about CPAP Nasal Masks

What you should know about CPAP nasal masks

Nasal CPAP masks are one of the best options for effective sleep apnea therapy. The benefits of using a nasal model instead of a full-face masks are numerous, but, unfortunately, not many patients are educated on the subject. Nasal masks are specially suited to fit your individual therapy needs, especially if you:

  • breath through your mouth at night;
  • are a side sleeper;
  • feel claustrophobic wearing a full-face mask;
  • or just want to read / watch TV at bed before going to sleep.

Is a nasal CPAP mask better?

So why is it better to opt for a nasal CPAP mask instead of a standard full face CPAP mask? First, let’s look into what nasal and nasal pillows CPAP masks have to offer compared to full face models.

What are the advantages of nasal CPAP masks?

Nasal masks are designed to provide freedom of movement during sleep apnea therapy. They are perfect for both side and back sleepers. Therapy wise, studies have shown that nasal CPAP masks help patients achieve better adherence to their prescribed therapy, without discontinuing it.

The new-generation nasal masks are designed to offer unmatched levels of performance, comfort and thorough seal over older models.

Why choose a nasal CPAP mask?



If your CPAP setting is 10 cmh20 and higher, then a nasal masks would likely be highly recommended by your doctor. However, please note that nasal CPAP masks are NOT recommended for mouth breathers or patients whose nasal passages are blocked.



A nasal mask is a specifically preferred choice of CPAP users who sleep with their mouth closed and can exhale through their nose. It is comfortable to wear, unobtrusive and easy to put on and off, while simultaneously providing a steady stream of pressurized air to the sleeper’s airways.



The smaller size of nasal CPAP masks is often preferred over full face masks. Patients who find nasal pillows uncomfortable at higher pressures opt for nasal masks instead to achieve a more comfortable and effective therapy.


Nasal or full face cpap mask comparison.

What are the main advantages of nasal masks compared to full-face masks: 

  • patients feel significantly more free in bed;
  • patients can turn in bed freely without risking seal bending or creaking;
  • patients enjoy better intimacy with their partners due to lower mask profile and less parts;
  • patient don’t feel trapped when we wearing a nasal mask;
  • patients increase their rate of adherence to their prescribed therapy.

Nasal CPAP masks come in different shapes and sizes, so most people can find a mask that works for them.

Nasal masks are less bulky than full face masks, making them less claustrophobic. Nervertheless, some patients might not get used to the contact the mask makes with the bridge nose and the upper lip.

Nasal masks support higher pressure settings without causing discomfort. And they are offered in a variety of designs including For Him and For Her.

 woman and man on bed before sleep apnea therapy cycle.

What is the difference between nasal masks and full face masks?

The main difference between nasal masks and full face masks is that nasal masks are put over the nose instead of on both the nose and the mouth. They are connected to the patient in the same way as full face masks; that is, through a tube connecting to the CPAP machine. The CPAP / BiPAP machine then in turn, pumps the pressurized air into the patient’s airways directly through the nasal opening of the mask.

NOTE: Nasal masks cover the patient’s nose and upper lip only. 

The new generation nasal masks  

The latest Resmed nasal mask come with many neat features worth stating. There are even models with over the head connection, such as the ResMed AirFit N30i . The N30i is an innovative nasal mask with huge advantages over standard models.

Adherence to CPAP therapy problem

Successful treatment of sleep apnea requires adherence to therapy 

Although effective, adherence to the sometimes life-saving CPAP therapy in most cases remains problematic. Especially for some patients who may not be accustomed to nasal masks. You can read about the severity of sleep apnea and its health effects here).

 Useful tips for successful CPAP therapy

Always remind yourself that you are undergoing home sleep apnea treatment to protect your health and prevent the serious health risks untreated sleep apnea goes hand in hand with.

Talk to your partner and encourage them to share their thoughts and possible concerns about your therapy. Learn about the many benefits of CPAP therapy. In most cases, it is a therapy that saves lives. And, please, talk to your doctor doctor if you have difficulty using your mask.

Why some patients fail to adhere to CPAP therapy? 

Many patients–requiring CPAP therapy to lead a normal life without the debilitating symptoms–fail to adhere to their therapy program and discontinue treatment prematurely. The reasons for this are various. Some patient for example feel somewhat uncomfortable with a large, full face mask. They can’t get used to it easily and give up. And the apnea appears again and again.


The perfect CPAP nasal mask

What are the disadvantages of sleeping with a nasal CPAP mask?

Although being the most preferred option for a mask, nasal models do have their drawbacks. Here are the main disadvantages of using a nasal sleep apnea mask:


  • They are not the most appropriate type of mask for patients who breathe mouth during sleep;
  • It is not recommended for patients suffering from sinusitis or a chronic condition that causes nasal congestion.

Choose a full face mask if:

  • You breathe through your mouth while you sleep;
  • Your therapy requires higher air pressure;
  • You have allergies or other conditions that prevent you from breathing through your nose;
  • You sleep on your back.

Obstructive Sleep Apnea And Driving: UK


Driving with Obstructive Sleep Apnea in the UK: Everything You Need to Know

If you live in the UK, you must tell the DVLA if you have obstructive sleep apnea syndrome or obstructive sleep apnea that affects your ability to drive safely. If you don’t, you can be fined up to £1,000 or, even worse, prosecuted if you cause an accident because of your condition. So be sure to consult with your physician if you’re not sure whether your OSA can affect your driving or not.

You and nobody else is responsible for deciding if you’re fit to drive or not. You might have sleep apnea or suffer from insomnia, or have a newborn that doesn’t stop crying at night. The reason is irrelevant. If you feel tired or sleepy during the day, to the point where it might affect your driving, then you MUST not drive. If you are told not to drive — by your GP, sleep doctor, or other medical professional — then you definitely must not drive. 


Should you drive if you have Obstructive sleep apnea?

If you know that you are suffering from any form of Sleep Apnea (obstructive, central or mixed) and if you go on driving, then you are breaking the law and risking your life and the life of others around you.

If you start noticing that you are feeling sleepy during the day, do not hesitate and consult your GP. If possible, bring to them your Epworth score (Epworth Sleepiness Scale or ESS). Your GP will refer you to sleep clinic where further diagnostic will be performed to understand the origin of your daytime sleepiness and whether it is caused by OSA or not.

Even if it is caused by some form of apnea, it might not mean that you are unfit to drive. If your daytime sleepiness is not excessive, than you can continue to drive and the DVLA does not need to be notified.

Do you have to inform the DVLA?

If you are diagnosed with moderate or severe sleep apnea, you really must not drive and inform the DVLA. You must not drive until your sleep doctor confirms that the prescribed therapy is working and minimizing the effects of OSA on your body. In most cases you will be prescribed the most effective sleep apnea treatment option, that is, CPAP therapy.

How to notify the DVLA?

The best way to notify the DVLA about having a medical condition that interferes with your driving is in writing instead of by telephone or e-mail.

What is excessive sleepiness and how it relates to driving?

As defined by the DVLA, the term “excessive sleepiness” should be interpreted as:

  • Excessive sleepiness likely to have an adverse effect on driving.

The term “drowsiness” should be interpreted also as excessive sleepiness.

Car and Motorcycle Drivers

1) If you are diagnosed with mild, moderate or severe OSA, without excessive sleepiness:

  • You may continue to drive as normal
  • You are not required to notify the DVLA.

2) If you are diagnosed with mild OSA with excessive sleepiness:

  • You must not drive until your excessive sleepiness is under control.
  • If your excessive sleepiness cannot be controlled within 3 months you must notify the DVLA.

3) If you have moderate or severe OSA with excessive sleepiness:

  • You must not drive until your sleep clinic has confirmed that:- Your OSA is under control;
    – Your sleepiness is no longer excessive;
    – You are complying with CPAP treatment.
  • You must notify the DVLA and send them your medical information proving that your symptoms are under control.
  • If your driving license has already been revoked, you can apply for it to be restored.

You must not drive until OSA has been diagnosed and the Sleep Clinic that diagnosed you has confirmed that your excessive sleepiness is being satisfactorily put under control by your prescribed treatment.

If you have mild OSA, you only need to notify the DVLA if your excessive sleepiness cannot be controlled within 3 months after beginning of treatment.

Bus and lorry (and taxi) drivers

If you have been diagnosed with mild, moderate or severe OSA but you don’t experience excessive sleepiness:

  • You may continue to drive. You do not need to notify the DVLA.

If you have been diagnosed with mild OSA and are experiencing excessive sleepiness:

  • You must not drive. At least not until your excessive sleepiness symptom has been successfully controlled.

If, within the span of three months, your excessive sleepiness symptom cannot be controlled you must notify the DVLA.

If you have been diagnosed with moderate or severe OSA and are experiencing excessive sleepiness:

  • You must not drive until your sleep clinic has confirmed to you that your OSA is under control, your sleepiness is no longer excessive, and you are complying with CPAP treatment;
  • You must notify the DVLA. The DVLA will ask for medical confirmation that will prove that your symptoms are controlled. If your driving license has already been revoked, you can apply for a renewal.

If you are experiencing excessive sleepiness and OSA is suspected:

  • You must not drive until your condition has been diagnosed and the Sleep Clinic that diagnosed you has confirmed that your excessive sleepiness is being satisfactorily controlled by prescribed treatment.

If you have been diagnosed with mild OSA, you only need to notify the DVLA if your excessive sleepiness cannot be controlled within three months.

If you are noticing that you are experiencing excessive sleepiness on a daily basis, do not drive!

  • Seek an appointment with your GP;
  • Ask your doctor to refer you to a Sleep Clinic;

How Many Hours of Sleep Do You Actually Need in 2020

How Many Hours of Sleep Do You Actually Need in 2020

You might be wondering how to stay sleep-debt free, how to avoid sleep deprivation even if you are a short sleeper, how to live healthy in a century of sleep disorders, insomnia, sleep apnea, and a plethora of celebrities boasting about how they sleep 2 hours a night and feel OK. Take Martha Stewart, for example. Here’s what she has to say on sleeping:

Martha Stewart Sleep Is Not The Most Important Thing Quote

Not many sleep experts would ever quote Martha (unless for the purpose of utterly disapproving that statement). Especially when we look at some of Martha’s other quotes taken from her ‘Health and Wellness’ section at her website:

‘Our bodies work hard for us and we need to do our best to keep them healthy, fueled, and well-rested. […] Here is how we make sure we eat right, get enough exercise, control stress, and squeeze in better sleep…because wellness should be all of our top priority.’


Martha Stewart reportedly gets about 3-4 of shuteye each night. Reportedly, so is Donald Trump, Madonna, Jay Leno and other celebrities who like to get stuff done while sleeping as little as their body allows.

Unfortunately, being ‘healthy’ and ‘well-rested’ and 4 hours of sleep do not go hand-in-hand.


The power of the ‘power nap’

Among other historical short sleepers are Nikola Tesla (2 hours a night when in an inventing phase), Thomas Jefferson (2 hours), and Benjamin Franklin (4 hours). Tesla, for example, was a practitioner of the so-called “power nap” technique where you take a 20-minute nap during the day to recharge your mind and reinvigorate your work process.

Another great Thomas (Edison) was also an advocate of the power nap technique. In fact, for him, the lack of sleep was a badge of honor, so he had no other option but to try and get some, albeit short, time of “power nap” during the day in order to combat his fatigue.

In fact, Edison was so fond of power-naps, he had a dedicated napping cot in his office, in addition to the cot he has set up in his library and laboratory.

Thomas Edison and his power nap routine.


So the moral of the story is that celebrities and geniuses need less sleep than us mortals?

Well, not exactly. Not even close to the truth, actually. Before we go further into that, let’s mention the historical sleepers who got things done only AFTER they have received their healthy dose of sleep each night.

Ernest Hemingway:

Ernest Hemingway I love Sleep Quote


Hemingway is just the first that comes to mind. Another genius historical sleeper is Albert Einstein, who was not a big fan of sleep deprivation, either. He slept a full 10 hours a night; sometimes even more. And, there’s also Winston Churchil, who made sure to get his 8 every single day.

But when it comes to geniuses, the finest example of a chronic sleep-lover is genius-prime Leonardo DaVinci, who took 20-minute ‘power naps’ every 4 hours of being awake!

Unfortunately, there are certain limits even with the power nap and geniuses. You cannot be carrying out a power-nap program without suffering the consequences of sleep deprivation. Your brain just hand handle it; and, eventually, rather soon than later, it will ask for a time-out, to try and recover what you have been doing to your body. If your brain fails to do so, you will be exposed to a particularly harmful sleep deprivation cycle which can have serious health risks.


At the other end of spectrum are people who have no choice but to sleep less

Sleep is more often than not caused not by a voluntary decision to work more and sleep less, but by an underlying sleep disorder. Emily Bronté is an example of chronic short sleeper not by choice or by following a ‘power-nap’ routine, but because of a terrible case of insomnia. In fact, her insomnia case was so severe that the great 19th-century poet and author of the timeless classic Wuthering Heights had to circle around her dining room table to try and get sleepy.

So why is sleep that important?

Sleep is—how to put it mildly—EXTREMELY important for the body. Chronic sleep loss can be extremely detrimental to our long-term health. The genes controlling our immune system simply rely on restorative sleep to maintain the body healthy. Not getting enough shuteye may affect heart health, weight and our body’s capability to deal with stress.

Sleep deprivation impairs both the body and the mind equally negatively, with the first to fall in battle being mental prowess, decision making and ability to perform daily tasks at full capacity.

So why not just reboot our entire body and with just sleeping? Sounds easy, right? Not if you suffer from a sleep disorder such as insomnia or sleep apnea.

Here is how many hours of sleep you need, according to researchers and sleep experts.

How many hours of sleep do you need each night blog post

How is the human gene affected by sleep deprivation?

Research conducted at the Sleep Research Center at the University of Surrey, England, has shown that not getting enough restorative sleep directly affects the functionality of several hundred of genes, such as the genes responsible for the immune system, the genes controlling weight gain, cognition and heart function.

Getting enough sleep each night is vital for keeping your body and mind in healthy shape. And, when you think about it, why not—it takes so little effort to do so.


But why is it so hard in practice?

Most people work 9 to 5. In order to have enough time to prepare for work and avoid traffic, the majority of people wake early; and have no time for an afternoon nap during the day. Then the evenings come and you have to shower, prepare for dinner, read a book/watch TV, and try and get into bed as soon as possible… or else, suffer the daytime consequences.

How many hours of sleep do we need each night?

How to improve your sleep?

Here are a few things you can do to go to bed early and have a good restorative sleep. Adopt a routine and follow it.

  • Leave work at work

Leave on time and also leave work behind when you go home. You can still work hard during the day, but when you enter your doorstep in the evening, make sure you leave all work-related thoughts outside. You can even leave the office later than take unfinished work home. It is really detrimental to your sleep.

  • Do not procrastinate your household duties and complete them on time

Once home make sure to complete your household business on time and go to bed preferably at one and the same time each night. Going to bed later than that will wreak havoc to your schedule and directly affect your sleep pattern.

  • Put your devices away half an hour before you go to sleep

It is of the utmost importance to not use your devices at least half and hour before you go to sleep. The short-wavelength, artificial blue light light from your TV, phone, tablet or laptop will make it harder to fall alseep because they suppress the release of melatonin. Melatonin is the sleep inducing hormone which your body naturally releases to put you at rest. If you don’t want to dusturb your circadian rhythm, make sure to go sleep.

  • Read in bed

Reading a book in bed both stimulates the brain and puts your entire body at ease. Reading in bed will also help with bad dreams, as long as you keep away from Stephen King’s horror masterpieces.

  • Do not think about work on weekends

Same as do not take work home, but applying for the weekends, too. Keep your thoughts away from how your week went at the office or what you have to do on Monday.

  • Healthy eating equals healthy sleeping

By decreasing the amount of saturated fats and sugar while focusing on healthier fiber-rich foods you can drift off and enter deep sleep much easier. Diet-stimulated heartburn can keep you up, so keep away from fried nor high-fat foods or alcohol. Adopt a balanced diet including fresh fruits and vegetables and low-fat proteins rich in B vitamins. It has been scientifically proven that B-vitamin foods can help the body produce the sleep-cycle regulating hormone melatonin.

  • Stay hydrated

Drink one glass of water just before bed. It will help you avoid experiencing thirst or dehydration while asleep. What happens during sleep is that you experience a sleep-induced fluid loss, simply by breathing. Especially if you breathe through your mouth, are a heavy snorer, or suffer from sleep apnea.

If you want to stay adequately hydrated, do not just rely on a cup of water before bed but make sure to drink non-caffeinated liquids throughout the day as well. And remember – no coffee after 6 PM.

Stay Hydrated to Avoid Sleep Deprivation.

  • Check yourself for sleep disorders

Did you know that there are more than 95 identifiable sleep disorders? Each with its own set of sleep-affecting symptoms. One of the most debilitating ones is obstructive sleep apnea (OSA), which is estimated to affects more than 900 million people on the planet.

To be absolutely sure that you don’t have OSA or suffer from some other form of sleep disorder, talk to your physician so they can assess your symptoms and possibly schedule a sleep apnea test. To read more about sleep disorders here.

Sleep Disorders


What to do if you indeed have obstructive sleep apnea?

No one can say the exact number of OSA sufferers because the vast majority of them do not even realize they have the disorder until diagnosed. To read more about obstructive sleep apnea, please visit our Sleep Apnea guide here. To learn about the other major types of sleep disorders, keep reading.

If your sleep deprivation is caused by a diagnosed sleep disorder such as obstructive sleep apnea, you should consider starting CPAP therapy in the comfort of your home. If you have signs of sleep apnea, have already been diagnosed with OSA, or have been prescribed PAP therapy, you can purchase a CPAP machine and mask to put an end to the debilitating effect this disorder has on your sleep and health.

Losing even an hour of sleep can have a significant impact on your organism, such as your cardiovascular health, the body’s ability to fight infection, and your ability to think clearly.

The body cannot adjust easily to irregular sleep schedules (jetlag syndrome being a prime example of this). The biological clock is not a mechanical one in order to tune into a different sleep schedule by the click of a button.

Quick facts:
About 40% of adolescents and children run into a certain form of sleep problem in their development phase



The quantity of sleep is not as important as the quality of sleep. Even if you put 8-9 hours to bed each night, if you wake up frequently at night or suffer from a sleep disorder, chances are these 9 hours would not even matter in feeling fully rested in the morning.
Sleeping more during weekends will not make up for the lack of restorative sleep during the week. Not to mention that sleeping more during the weekend can disturb your sleep cycle and make it hard to wake up early on Monday.

The average adult needs seven hours of sleep per night, although this can lead to chronic sleep deprivation. Combined with an underlying sleep disorder, 7 hours of sleep per night is a recipe for disaster, which is why it is so important to address the problem as soon as possible. With the advancement of age, the more hours you need to get a good night’s sleep.

Is Sleep Apnea Hereditary: The Genetic Pattern in OSA

Is obstructive sleep apnea hereditary blog post cover.

Obstructive sleep apnea is a debilitating condition causing severe pauses in breathing during sleep by partially or completely blocking the upper airways. Both partial and complete forms of apnea impact the sleeper’s oxygen intake, which in turn leads to a range of serious side symptoms and complications. There are three types of sleep apnea—obstructive, central, and mixed apnea. Today we will focus on the most widespread type—obstructive sleep apnea, or OSA .

Ask any OSA sufferer about sleep apnea symptoms and they will produce a list of these, including interrupted sleep and frequent awakenings to severe daytime sleepiness or fatigue, and, of course, the usual suspect—loud snoring interrupted by gasping sounds. Beneath the tip of the iceberg of OSA signs is an underlying bulk of health complications that the sleeper might not even suspect they are exposed to.

Among these health complications are low blood oxygen levels (hypoxemia), high blood pressure (hypertension), insulin resistance, Alzheimer’s disease and more. The disorder leads to a higher risk of stroke and heart failure, impairs your memory and ability to focus, causes morning headaches, sexual dysfunction and depression. All of the above are caused by what may seem like a simple upper-airway blockage happening at night.

Sleep apnea: frequently asked questions with answers

Does sleep apnea run in the family?

The short answer to this question is: Yes, obstructive sleep apnea is partly hereditary and may run in the family. But this is the overly simplified answer. Unfortunately, nothing about sleep apnea is simple.

OSA is a condition that may be inheritable from first degree family members. For example, children can inherit from their parents their facial features, anatomical characteristics of the upper airway muscles, high body-mass index and tongue size. The anatomy of the tongue may be passed through in family history and lead to developing OSA as the tongue affects the apneic collapse of the soft tissues in the upper-airway during sleep.

The longer answer to this important query, however, needs to be grounded on scientific examination and genetics studies providing  concrete results. This is what this article will explain today—the scientific approach to examining the correlation between OSA and genetics, and how exactly that relates to the broader field of study on sleep disorders up until 2020.

Inheritance across age groups and populations

Sleep disorders are present in all age groups and populations, with a strong evidence of genetic inheritance in disorders like narcolepsy and restless leg syndrome. In the case of obstructive sleep apnea the inheritance pattern is still to be defined. And while the genetic etiology of sleep apnea remains rather unclear, sustainable progress in regard to establishing a relationship between apnea and our genes has been made in recent years, with plenty of scientific data to back that up.

We have already exhausted the topic of risk factors in OSA cases, such as middle age, obesity and gender. The approach to establishing heterogneity and etiology in regards to OSA rests on scientific evidence acquired from documented studies with thousands of volunteering participants across all ages and gender, many of which suggest that the genetic component of OSA in the range of anything between 0 and 40%, while the rest remains in the graph secondary factors.

Inheritance pattern in first-degree relatives

The genetic predisposition in developing sleep apnea still remains largely undefined, in spite of the thousands of conducted studies during the last three decades. Today the inheritance patterns in obstructive sleep apnea (OSA) point to a relation between first-degree relatives with OSA and the presence of the disorder in siblings and children, where the risk of developing apnea is around 50% and greater.

As multifunctional sleep disorder OSA does have a heritable dimension researched primarily through field synopsis and genetic association examination of focus groups of participants. Conducting genetic association OSA studies aims at identifying odds ratios while exploring the connection between population-based and family-based testing. The results try to find an inheritance pattern of OSA by utilizing the existent findings in the developing field of OSA genetics through complex genotyping methods and broad genetic testing.

Genetic inheritance in obstructive sleep apnea.

Genetic sleep apnea testing

Genetic sleep apnea testing analyzes alterations in chromosomes, genes, or proteins in OSA sufferers in order to confirm or exclude a genetic predisposition to the disorder. This type of testing examines the possibility that the patient developed OSA partly due to genetic passing. The methodology utilized in genetic testing is based on gene, chromosomal and biochemical gene tests.

  • Gene tests examine the possible variations and mutations in the lengths of DNA that could cause the disorder;
  • Chromosomal tests examine long lengths of DNA or chromosomes in an effort to detect major genetic alterations that could lead to the disorder;
  • Biochemical gene tests, examine how proteins behave and if they could change the DNA and lead to OSA.

Genetics of neck circumference and OSA explained

The relationship between neck circumference, general obesity and OSA is one of the most well-documented ones to this date. Nine in ten  sleep apnea tests asks the same question: ‘Is your neck circumference greater than 17 inches (men) / 16 inches (women)’?

Obesity index, soft palatal length and palate-to-spine angle are constantly studied through research to drive a meaningful correlation between these factors and obstructive sleep apnea. Studies have found that the link between anatomical features and OSA is not as important a factor as neck circumference.

The OSA inheritance factor in obese children

The genetic predisposition and general cause for developing obstructive sleep apnea in children relies on a variety of different factors–both anatomic and neuromuscular. Susceptibility to obstructive sleep apnea in children has proven extremely difficult and is still reliant on future studies and technological advancement. So far studies have shown that children can inherit their parent’s facial anatomy, such as large tonsils and large overbite and chin, which are factors for developing OSA.

Understanding the genetic risk factors as the first step to OSA prevention

In order to encourage early diagnosis and prevention, predictive models in genetic and phenotypic studies need to be established beyond the only suggestive framework of the current results. Steps in OSA prevention can help reduce morbidity and hesitance in the public’s approach to obstructive sleep apnea early diagnosis and treatment by educating the most genetically exposed groups of the population about the risks. The ultimate goal is to reach a proven prescriptive framework that would steer prevention and underline the benefits of early lifestyle changes reducing the chance of developing the disorder in the first place.

Why is it so difficult to understand if OSA is inherited or not?

Just like any other field of study focused on underpinning sleep disorders, genetics research of OSA is focused on early recognition and meaningful results that would increase public awareness about apnea. Until this happens, the genetic foundation of obstructive sleep apnea (OSA) still needs to be established. The difficulty in effectively studying if OSA is hereditary comes from the fact that, so far, physiological metrics across a sufficient range of genetic and phenotypic markers and participants is too costly and invasive to acquire.

The problem with the majority of genome-wide association studies trying to touch upon this extremely challenging topic is that they still remain suggestive instead of conclusive, and that most of them have not been consistently replicated.

The future of OSA genetics studies

Even with large numbers of patients taking participation in OSA studies, coverage across a wide gene region is problematic in regards to obtaining a solid statistical framework in regards to sleep apnea and its genetics origins—especially results that are robust to alternative genetic models. Genetic studies in OSA up to 2020 only find a small non-overlapping relation, without covering enough gene variants to identify a more solid ground for a positive association between the human gene and OSA. Such associations are still subject to variables posing a significant challenge to the global concern that is OSA.

Top 10 Signs of Sleep Apnea

Top 10 signs of obstructive sleep apnea cover image.

Picture this. You wake up in the morning with the feeling that you didn’t sleep at all. Something was just wrong. You know you snore a lot, but snoring can’t be blamed for that, right? Well, no. But loud snoring and inability to get a good night’s sleep can definitely be a telltale sign that there is an underlying cause for both. There is a range of symptoms that can give away that there is something wrong with your sleep at night. Today we grouped them in a neat collection of top 10 sleep apnea signs that you may not be aware about. Read on to learn more about this serious sleep disorder.

More than simple snoring

Signs of sleep apnea snoring with a sleeping cat.

You may be surprised how many people feel what we just described above. The fact is that more than a quarter of adults experience the same signs and symptoms that you may have experienced. Al lot of these are possible telltale signs of obstructive having sleep apnea (OSA).

The scary part is that you may be suffering from sleep apnea without even realizing it. If you happen to experience the following symptoms, chances are that you actually do have OSA.

The top 10 signs of obstructive sleep apnea

If you experience one or more of these symptoms on a regular basis, schedule an appointment with your doctor to understand the underlying cause. Here are the top 10 ten sleep apnea symptoms that you should know about:


  1. Loud snoring;
  2. Episodic stops of breathing and awakenings during sleep;
  3. Morning headaches;
  4. Waking with a dry mouth;
  5. Increased blood pressure;
  6. Low blood oxygen levels;
  7. Having trouble focusing;
  8. Daytime sleepiness and fatigue;
  9. Daytime irritability and mood swings;
  10. Inability to get a good restorative sleep (no matter how many hours of sleep you get).

Loud snoring

Many people snore regardless of age and gender. Although not every heavy snorer has obstructive sleep apnea, the majority of OSA sufferers are also loud snorers. In fact, loud snoring is the most frequent telltale sign of sleep apnea. That is because with sleep apnea your upper airways become obstructed at night, which contributes to heavy snoring. The OSA obstruction, combined with a narrowing of the airways, creates the snoring sound that your bed partner might have become all too familiar with.

Episodic gasping for air during sleep

The meaning of the term ‘apnea’ (apnoea, Greek) means a temporary cessation of breathing during sleep. When the breathing cessation occurs, it is up to your brain to immediately understand what is happening to your body and send a panic signal to it to resume your breathing. This panic signal causes the lungs to emergency activate again, making you choke or gasp for air as your body overcomes the apnea. For as long as you experience the obstructions, these brain-stimulated micro-awakenings are going to happen. And they’ll continue to make you gasp for air again and again throughout the night–until the morning clock rings and it’s time to go out of bed and deal with the aftermath.

Gasping for air during sleep.

Waking with a dry mouth

A combination of snoring and sleep apnea most often leads to waking with a dry mouth. And, dry mouth comes with its own group of additional complications–like sore throat, bad breath, and constant thirst. Studies have found that 1 out of three OSA sufferers that don’t use a CPAP machine experience dry mouth symptoms in the morning. On the other end of the spectrum, the majority of CPAP users stop experiencing early morning dry mouth due to their PAP devices do not even allowing the OSA obstruction to happen in the first place. What’s more, many of the contemporary CPAP devices have built-in humidifiers that prevent dry mouth.

Trouble concentrating

Starving the brain out of oxygen during apneic events inevitably affects brain function, research has shown. Studies have also shown a correlation between healthy brain chemical levels and OSA, with altered levels leading to having difficulty concentrating and memory problems.

In short, if you don’t get enough restorative sleep, your brain can’t adequately regulate the required chemicals for full cognitive functionality. This is especially true in regards to the required levels of gamma-Aminobutyric acid (GABA). GABA is the chemical responsible for staying calm and focused.

Studies have found that sleep apnea also affects the levels of glutamate, which is responsible for normal brain function.

Increased blood pressure and low blood oxygen levels

Sleep apnea causes extreme pauses in breathing during sleep. Each of these pauses causes a sudden drop in blood oxygen levels, and puts additional stress on the cardiovascular system.

During these pauses, the brain sends signals to the blood vessels to in crease the oxygen delivery to the heart so that your organism can compensate for each drop. However, the sudden increase of blood flow puts pressure on the blood vessel’s walls, which, in turn, increases the risk of high blood pressure (hypertension).

Morning headaches

Starving the brain of oxygen during apneic events causes the arteries to dilate to increase blood flow. The dilation naturally increases the exerted pressure in the head which, in combination with constantly interrupted sleeping cycle, causes morning headaches.

Daytime sleepiness and fatigue

Feeling tired all day after a ‘normal’ night with sleep apnea is one of the most common symptoms of the sleep disorder–and one of the most debilitating ones, too. In fact, any sleep-disturbing disorder comes with daytime fatigue. Your body simply cannot get the rest it needs.

Irritability and mood swings

Sure, you had a bad night of snoring and gasping for air all the time. But no one would really understand that–especially if you are constantly cranky and irritable around them. Trying to explain that your bad mood is caused by lack of a good night’s sleep and because your brain doesn’t receive much GABA chemicals is definitely an option, but hands down the best thing you can do is take action see the doctor.

Irritability and sleep apnea infographic.

Constant awakenings at night

Waking too often at night? Having to go the bathroom in the middle of your REM sleep? These are yet another ‘pleasant’ symptoms going hand in hand with sleep apnea. Irregular breathing and loud apneic snoring would most likely interrupt your sleep (and, unfortunately, your bed partner’s sleep as well).

Increased stress levels and increased risk of depression

Decreased blood oxygen levels and impaired cardiovascular system leads to extra exertion on your body, high blood pressure and high stress levels. New studies have shown that patients with obstructive sleep apnea have higher levels of the neurotransmitter glutamate and low levels of the GABA neurotransmitter. Dysfunction of glutamatergic neurotransmission is considered to be a core feature of stress-related mental illnesses.


top 10 sleep apnea signs 2019 blog post.

In almost any list of top 10 sleep apnea symptoms one can run into loud snoring, breathing pauses, sounds of choking or gasping for air during the night, daytime fatigue and more. The point of this informational article, however, is not just to list these signs of OSA, but to convey the idea that none of these symptoms is something you should tolerate and live with. So take matters into your own hands and make an appointment with a sleep specialist who can diagnose you and recommend treatment options for sleep apnea if you indeed have one.
