Sleep Apnea: The Ultimate Guide 2020

Sleep apnea guide 2020.

What is Sleep Apnea?

Sleep apnea is a disease of the upper respiratory tract. Obstructive sleep apnea (OSA) is the most common form with the second most common being central sleep apnea, which is a neurological disorder. Often underestimated and left untreated, sleep apnea is an extremely serious condition with serious consequences for the body. Sleep apnea is a disorder capable of causing – or complicating – other serious conditions such as Cardiovascular disease, hypertension, type 2 diabetes, liver disease and many other side conditions.

Obstructive sleep apnea

The most common form, OSA, is characterized by frequent stops of breathing during sleep, when the muscles in the back of the throat temporarily relax and as a result block the airway.

When occurring at night during a night’s sleep obstructive sleep apnea blocks the airways completely or partially, usually stopping the sleeper’s breathing for 10-20 seconds. The blocking causes a sudden drop in blood oxygen levels while the sleep apnea events themselves cause the brain to “wake-up”, re-activate and trigger frantic panic signals to the body, so as to make the it to resume breathing (the so-called micro awakenings).

Most people do not remember brain-induced micro-awakening during REM and non-REM sleep. When apneas occur more than 30 times per hour, the result is a complex negative impact on our sleep cycle and the very functioning of our bodies.

What triggers sleep apnea events?

Sleep apnea may occur spontaneously as we age, or it can be drug-induced by medications containing 5-hydroxy tryptamine molecules. It can also occur mechanically as a result of asphyxia. Another cause of its occurrence are throat traumas and neurological disorders.

What are the symptoms of obstructive sleep apnea?

Some of most common symptoms of a OSA include sudden awakening (caused by a feeling of asphyxiation or shortness of breath), restless sleep, sleeplessness, and lack of energy during the day.

What are the complications of obstructive sleep apnea?

Just like many other serious health disorders, OSA comes with it an array of complications and side effects.

Sleep apnea complications 2020

  • Daytime sleepiness and fatigue

The numerous awakenings at night that are caused by sleep apnea interfere with our normal restorative sleep, leading to our bodies feeling fatigued. Drowsiness, sudden mood swings and irritability are common side effects of the disorder.

  • Difficulty concentrating

Due to the dysfunctional restorative sleep at night, people suffering from obstructive sleep apnea often experience difficulty at concentrating during the day. Vehicle operators requiring high level of concentration, may suffer from sleep apnea side effects that could have a direct negative impact on their accident reaction response.

  • High irritability and mood swings.

Irritability and mood swings are other common side effects of sleep apnea as a result of the lack of good night’s sleep and the inability of the body to restore itself.

  • Cardiovascular problems and high blood pressure

Sudden drops in blood oxygen levels occurring during sleep apnea events increase blood pressure and our overall exertion of our cardiovascular system.

  • Higher risk of high blood pressure (hypertension).

Obstructive sleep apnea could increase the risk of recurrent heart attacks, stroke, and cardiac arrhythmia. In the presence of heart disease, low blood oxygen levels can lead to sudden death triggered by arrhythmia.

  • Complications with patients with type 2 diabetes

OSA increases the risk of developing insulin resistance in patients with type 2 diabetes.

  • Metabolic syndrome complications

Metabolic Syndrome, also called “Syndrome-X” and is caused by a combination of risk factors such as high blood pressure, high cholesterol levels, blood sugar, and big waist circumference. The syndrome is associated with increased risk of cardiovascular disease directly correlated to sleep apnea.

  • Complications with surgery and certain medications

OSA is a factor affecting drug intake drugs and patients undergoing general anesthesia. OSA also can make it more difficult to regain consciousness after surgery. This is why it is important to inform your doctor that you have apnea before undergoing a planned operation.

  • Depriving the partner of a good night’s sleep

Snoring often keeps our partners from getting a good restorative sleep.

What are the risk factors of obstructive sleep apnea?

Factors that significantly increase the risk of obstructive sleep apnea are excessive weight, large neck circumference (greater than 16 inches), narrowed upper airway, age, sex (men aged 60 or older are twice as likely to develop sleep apnea), smoking, alcohol consumption, high blood pressure and genetic predisposition.

For central sleep apnea the main risk factors are: age (occurs often in the middle-aged or elderly), sex, medical conditions (such as heart or kidney problems), use of certain drugs, some neurological problems.

What is Positional Obstructive Sleep Apnea (POSA)?

With OSA the breathing cessation occurs when the soft tissues of the upper respiratory tract and tongue relax preventing normal breathing. But there also another factor acting a sleep apnea catalyst – our position during sleep. Positional sleep apnea occurs (POSA) when the breathing events occur when we sleep in a certain position. In the majority of cases, POSA occurs when we sleep on our back, with the head in an upward position.

Home sleep apnea testing: is it reliable?

Home sleep apnea testing is easily done easily with the help of specialized apnea screening devices. These portable monitors record and analyze the sleeper’s breathing, recording sleep apnea events, snoring and blood oxygen saturation. Sleep apnea testing devices for home diagnostics have become increasingly popular due to their compact size and precision.

The data from the midnight analysis is then downloaded and interpreted by a doctor, who would analyze your Apnea–Hypopnea Index (AHI). AHI will indicate the severity of your apnea as it represents the number of apnea and hypopnea events per hour of sleep. If AHI shows that there have been 5-30 events per hour, this would indicate the presence of mild to advanced sleep apnea disorder. An AHI over 30 stops per hour would indicate that the disease is in an extremely advanced stage. This means that you should seek help as soon as possible.

What are the best treatment options for obstructive sleep apnea?

The best sleep apnea treatment has always been the continuous positive airway pressure (CPAP) therapy. CPAP devices come in two variations – standard or automatic – and are the preferred method for treating OSA at home. CPAP machines deliver constant pressurized air to nose through a hose and mask. By increasing the air pressure in your throat CPAP machines keep your airway always open, maintains normal oxygen levels in the blood and preventing constant micro-awakenings. This type of personal treatment tailored to your specific condition has been proven to be the most effective method for treating the condition.

Alternative treatment options for OSA include

In addition to the most effective treatment that is PAP therapy, there are a number of alternative treatment options for OSA with varying effectiveness depending on apnea severity and patient anatomy. Here are the most popular ones:

  • Hypoglossus nerve stimulation (HNS)
    A procedure wherein an implant is inserted in the patient’s chest through surgery. Once inserted and later activated by the patient, the implant starts analyzing their breathing pattern and stimulates a nerve that keeps the upper airway open throughout the night. HNS treatment is sometimes prescribed when standard PAP treatment proves ineffective or the patient don’t tolerate it.
  • Expiratory positive airway pressure
    Expiratory positive airway pressure (EPAP) utilizes adhesive valves placed over the OSA sufferer’s nose during sleep. Upon inhalation and exhalation, the valve opens and tries to keep the airway open in order to prevent obstruction. The problem with this type of therapy is that when EPAP becomes is excessive, the patient often has difficulty breathing in as research has shown that lung compliance decreases at higher volumes. Expiratory pressure therapy may result in trapping of air in the lungs as the EPAP devices do not allow the sleep apnea sufferer to to adjust the resistance to a comfortable level without pressure buildup and sacrificing tidal volume and sleep comfort, which is extremely important to people with OSA.
  • Surgery
    Although surgery may look like a direct problem solver, unfortunately in the majority of cases it is not. Surgery is used for severely overweight or obese OSA sufferers, where body weight significantly complicates the condition. The procedure depends on each patients anatomy and has a variable efficacy by addressing the primary reason for the obstruction – severe narrowing of the airway.
  • Behavioral treatment
    Behavioral treatment includes changes in the patient’s sleep habits and general lifestyle. Weight loss is a prime example of making such a behavioral change, just like avoiding smoking and excessive alcohol consumption. In addition, if the apneic events occur when the sleeper assumes particular position during sleep (positional sleep apnea), it may be recommended that they start sleeping on their sides.

Is surgery for sleep apnea effective?

Although the vast majority of people with sleep apnea tend to choose the non-invasive treatment that CPAP machines provide, surgery options also exist. Operative treatment for OSA is usually applied in extremely dangerous cases where standard CPAP treatment does not help. Interventions may may include:

  • Uvulopalatopharyngoplasty (UPPP) – a surgical procedure aimed at removing excess tissue from the soft palate and pharynx.
  • Nasal surgery – operative intervention aiming at removing nasal obstruction that may cause OSA, such as in the septum, turbinates, and nasal valve areas.
  • Soft palate implants – also called Pillar Procedure where three polyester rods are inserted into the soft palate.
  • Hyoid advancement – surgical repositioning of the small hyoid bone in the neck.
  • Tongue advancement – advancing the genioglossus muscle forward in order to reduce the tongue’s backward recession during sleep.
  • Reduction of the tongue base – reducing the base tissue form the tongue or performing direct excision of the tongue.Lingual tonsillectomy – removal of the tonsillar tissue near the back of the tongue.

 

Before deciding on a surgical intervention, by all means consult with your doctor in order to learn if surgery is actually necessary.

Each of these surgical procedures has its risks and cons when addressing of the condition. This is the primary reason for OSA patients to prefer treating sleep apnea non-invasively with CPAP devices.

BROWSE CPAP DEVICES FOR SLEEP APNEA TREATMENT

More about CPAP machines

Modern CPAP machines are quiet and intuitive devices that intercept snoring sounds and apnea events. When these events are detected, the device begins to supply customized flow of oxygen to counteract them. Once the optimum level of pressure has been reached, the machine starts maintaining the optimal level for some time, then reduces it and “waits for” until the next sleep apnea event.

Inside, CPAP machines feature miniature smart air compressors running on electricity or on battery. The most advanced BIPAP (Bilevel positive air pressure) models come with premium perks such as remote monitoring, advanced event detection, EasySleep function, high-quality noise filters, humidifiers, detailed patient statistics and car compatibility.

Why use CPAP instead of seeking other methods to treat your OSA?

An increasing number of scientific studies in 2019 have shown that obstructive sleep apnea is increasingly being associated with memory problems, impaired congitive function and poor decision-making. The use of modern CPAP devices reduces the risk of cardiovascular disease and prevents gradual damage to the brain due to insufficient supply of oxygen. OSA treatment with CPAP devices is the most effective way to achieve normal memory function through a healthy night’s sleep. In addition, it has been scientifically proven that CPAP therapy reduces the risk of stroke, heart attack and type 2 diabetes.

What is the difference between CPAP, APAP, BiPAP, and VPAP devices?

APAP machines, just like CPAP ones, are non-invasive treatment for sleep apnea, delivering pressurized air via a nasal or a full-face mask. The abbreviation APAP stands for Automated Positive Air Pressure, based on the same technical principle as CPAP machines.

BiPAP devices (short for Bilevel Positive Airway Pressure) and have a very similar function to CPAP machines in that they supply optimized pressure to keep the airway from collapsing, helping you breathe easily during sleep.

VPAP stands for Variable Positive Airway Pressure. VPAPs are auto-adjusting and very similar to BIPAP machines. They provide pressure to match the patient’s natural breathing pattern while preventing cessation of breathing caused by obstructive sleep apnea events. The major difference between VPAP and BiPAP machines is that the former can be used to treat other sleep disorders as well as some forms of lung disease.

Complications associated with CPAP therapy?

The most common complications associated with CPAP therapy are dry mouth, red facial marks (inflamed skin) and claustrophobic sensation.

  • dry mouth;
  • red facial marks (inflamed skin);
  • claustrophobic sensation;
  • runny nose;
  • forced air intolerance.

Dry mouth is the most common complication, especially when exacerbated by the use of nasal masks, and when the sleeper’s jaw drops during sleep.

Consult your physician if any of these side symptoms during your CPA therapy, considering how important it is to adhere to it in order to benefit from a successful sleep apnea therapy.

How to get a CPAP device tailored to my pressure needs?

Purchasing a CPAP device is one of the most important steps in starting successful sleep apnea. It is important to invest in the right device for your specific condition and prescribed pressure.

Word origin of the term

The term “apnea” derives from the ancient Greek word “breathless” (Gr. Apnous > apnoia > apnoea) describing the temporary suspension of breathing during sleep. The ancient Greek definition of the disоroder reflects the condition in which the breathing muscles block the airflow to the lungs.

(Apnea, in the classical sense of the term, may also appear in times of distress, negative emotion and during crying).
