What does term sleep apnea mean?
Sleep apnea is a sleep disorder characterized by pauses in breathing or instances of very low breathing during sleep. Each pause in breathing, called an apnea, can last from at least ten seconds to minutes, and may occur 5 to 30 times or more an hour. Similarly, each abnormally low breathing event is called a hypopnea.

However, if you suffer from severe enough sleep apnea, you may meet eligibility standards with the other symptoms resulting from your sleep apnea. To qualify for benefits, you must meet SSD's definition of disabled.
Does your heart stop when you have sleep apnea?
Researchers suspect sleep apnea causes abnormal heart rhythms, which lead to sudden cardiac death, for a number of reasons. “Sleep apnea may lower oxygen levels, activate the fight-or-flight response and change pressure in the chest when the upper airway closes, stressing the heart mechanically,” he explains.
Does sleep apnea happen every night?
What is sleep apnea? Sleep apnea is a serious sleep disorder. People who have sleep apnea stop breathing for 10 to 30 seconds at a time while they are sleeping. These short stops in breathing can happen up to 400 times every night.
Can you get rid of sleep apnea?
CPAP and oral appliances work well, but they're not cures for sleep apnea. The only sure way to rid yourself of the condition for good is to either lose weight or have surgery to remove excess tissue from the palate or throat. Surgery can have side effects, which is why it's usually viewed as a last resort.

What is the name of the condition where the muscles in your throat are closed?
Close. Obstructive sleep apnea. Obstructive sleep apnea. Obstructive sleep apnea occurs when the muscles that support the soft tissues in your throat, such as your tongue and soft palate, temporarily relax. When these muscles relax, your airway is narrowed or closed, and breathing is momentarily cut off.
Why is sleep apnea more likely to be a problem after surgery?
People with sleep apnea might be more likely to have complications after major surgery because they're prone to breathing problems, especially when sedated and lying on their backs.
What does it mean when you snore loudly?
Sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts. If you snore loudly and feel tired even after a full night's sleep, you might have sleep apnea .
Does sleep apnea cause diabetes?

Does sleep apnea cause high blood pressure?
Having obstructive sleep apnea increases your risk of high blood pressure (hypertension). Obstructive sleep apnea might also increase your risk of recurrent heart attack, stroke and abnormal heartbeats, such as atrial fibrillation.
What are the symptoms of sleep apnea?
Signs and symptoms. People with sleep apnea have problems with excessive daytime sleepiness (EDS) and impaired alertness. OSA may increase risk for driving accidents and work-related accidents. If OSA is not treated, people are at increased risk of other health problems, such as diabetes.
What is the most common category of sleep-disordered breathing?
Airway obstruction during sleep. Obstructive sleep apnea (OSA) is the most common category of sleep-disordered breathing. The muscle tone of the body ordinarily relaxes during sleep, and at the level of the throat, the human airway is composed of collapsible walls of soft tissue that can obstruct breathing.
How does sleep apnea affect respiration?
In pure central sleep apnea or Cheyne–Stokes respiration, the brain's respiratory control centers are imbalanced during sleep. Blood levels of carbon dioxide, and the neurological feedback mechanism that monitors them, do not react quickly enough to maintain an even respiratory rate, with the entire system cycling between apnea and hyperpnea, even during wakefulness. The sleeper stops breathing and then starts again. There is no effort made to breathe during the pause in breathing: there are no chest movements and no struggling. After the episode of apnea, breathing may be faster (hyperpnea) for a period of time, a compensatory mechanism to blow off retained waste gases and absorb more oxygen.
How many countries use CPAP?
Only 15% of developed countries use CPAP machines, in developing countries it is closer to only a 1% adoption rate. Without treatment, sleep apnea may increase the risk of heart attack, stroke, diabetes, heart failure, irregular heartbeat, obesity, and motor vehicle collisions.
How many people have OSA?
OSA is a common sleep disorder affecting 936 million—1 billion people globally, or roughly every 1 in 10 people, and up to 30% of the elderly. Sleep apnea is somewhat more common in men than women, roughly a 2:1 ratio of men to women, and in general more people are likely to have it with older age and obesity.
Why do I have sleep apnea?
Excess body weight is thought to be an important cause of sleep apnea. People who are overweight have more tissues in the back of their throat which can restrict the airway, especially when sleeping. In weight loss studies of overweight individuals, those who lose weight show reduced apnea frequencies and improved Apnoea–Hypopnoea Index (AHI). Weight loss effective enough to relieve obesity hypoventilation syndrome (OHS) must be 25–30% of body weight. It is difficult to achieve and maintain this result without bariatric surgery.
How many episodes per hour of sleep apnea?
In many cases it is first observed by a family member. Sleep apnea is often diagnosed with an overnight sleep study. For a diagnosis of sleep apnea, more than five episodes per hour must occur.
What causes central sleep apnea?
Possible causes of central sleep apnea include heart or neuromuscular disorders , and treating those conditions might help. Supplemental oxygen. Using supplemental oxygen while you sleep might help if you have central sleep apnea. Various forms of oxygen are available with devices to deliver oxygen to your lungs.
What to do if you have sleep apnea?
For milder cases of sleep apnea, your doctor may recommend only lifestyle changes, such as losing weight or quitting smoking. If you have nasal allergies, your doctor will recommend treatment for your allergies.
What is a CPAP machine?
With CPAP (SEE-pap), the air pressure is somewhat greater than that of the surrounding air and is just enough to keep your upper airway passages open , preventing apnea and snoring .
How to stop snoring and sleep apnea?
To eliminate snoring and prevent sleep apnea, your doctor may recommend a device called a continuous positive airway pressure (CPAP) machine. A CPAP machine delivers just enough air pressure to a mask to keep your upper airway passages open, preventing snoring and sleep apnea.
What tests are done to detect sleep apnea?
Tests to detect sleep apnea include: Nocturnal polysomnography. During this test, you're hooked up to equipment that monitors your heart, lung and brain activity, breathing patterns, arm and leg movements, and blood oxygen levels while you sleep. Home sleep tests.
What is a sleep specialist?
You're likely to be referred to a sleep disorder center. There, a sleep specialist can help you determine your need for further evaluation. An evaluation often involves overnight monitoring at a sleep center of your breathing and other body functions during sleep. Home sleep testing also might be an option.
Is CPAP better than oral appliances?
Another option is wearing an oral appliance designed to keep your throat open. CPAP is more reliably effective than oral appliances, but oral appliances might be easier to use. Some are designed to open your throat by bringing your jaw forward, which can sometimes relieve snoring and mild obstructive sleep apnea.
What is the most common form of sleep apnea?
Obstructive Sleep Apnea (OSA) When you hear someone say they have sleep apnea it’s likely they are referring to Obstructive Sleep Apnea—the most common form of sleep apnea. OSA is a sleep disorder in which the soft tissues of the mouth and throat expand and relax during sleep.
What are the three groups of sleep apnea?
OSA is classified into three groups: mild, moderate, and severe . Each group refers to the average number of times per hour the sleeping individual suffers from an interruption in breathing. Each one of those events counts as one event in the apnea-hypopnea index (AHI), which is then used to determine whether a person has mild, moderate, or severe sleep apnea .
What does CompSA stand for?
To simplify the alphabet soup of acronyms, Complex Sleep Apnea is sometimes abbreviated in medical research as CompSA to avoid any confusion between it and Central Sleep Apnea (CSA), so we’ll also use that same term throughout to describe Complex Sleep Apnea.
What is CSA in sleep?
Central Sleep Apnea. CSA is a less common form of sleep apnea compared to OSA. It is generally caused by medical concerns that affect the brain. CSA is a condition in which the signals to breathe are not sent by the brain, and as a result, the person does not draw a breath.
How low should your AHI be on a CPAP machine?
If your sleep apnea treatment is working, you should see the AHI readings on your CPAP machine below five, and it may be as low as one. Your results will vary, but keeping an eye on your AHI is a good way to see how your treatment is going.
How does a CPAP machine work?
CPAP therapy is the most common treatment for OSA. It works by introducing a constant flow of air from your CPAP machine into your mask. The continuous pressure helps keep your airway open and respiratory function at normal levels, which allows for easier breathing during sleep.
How many types of sleep apnea are there?
Add a header to begin generating the table of contents. Unless you are brand new to sleep apnea, you likely know by now that there are three types of sleep apnea: Obstructive, Central, and Complex Sleep Apnea. If you are new to sleep apnea treatment, then you’ve come to the right place to further understand it and how you can find ...
What type of machine is used for sleep apnea?
Three Main Types of Sleep Apnea Machines 1 CPAP. After completing your sleep study, your physician may prescribe you a CPAP machine along with the exact air pressure setting you need to help you breathe while asleep. This air pressure is a constant flow set to the same pressure setting all night. You breathe in with the assistance of this pressure setting, and you exhale against this same pressure setting. CPAP machines are the most popular for treating OSA. 2 APAP. An APAP machine is automated to work within a pre-set pressure range. An APAP machine automatically adjusts throughout the night to fit your specific pressure needs on a breath-by-breath basis. This makes APAP machines more comfortable. 3 BiPAP. BiPAP stands for bi-level positive airway pressure. As the name implies, a BiPAP machine offers two levels of airway pressure: one for inhalation and another one for exhalation. BiPAP machines allow those with severe OSA to cycle air in and out of their lungs easier.
What is the best position to sleep for sleep apnea?
You sleep on your side. If you sleep on your side, which is one of the preferred sleeping positions for sleep apnea, your number of apnea events may decrease. The APAP can adjust the air pressure depending on your sleep position, so you don’t need to use the highest pressure setting at all times.
What are the similarities between APAP and CPAP?
Now that you have a better grip on what makes each machine stand out, the major similarities between APAP, BiPAP , and CPAP machines are that they all help to open your airway and facilitate breathing while you sleep, reducing the number of apnea events.
What is the pressure range for CPAP?
Your pressure settings are measured in centimeters of water (cmH2O). Most CPAP and APAP machines can be set to anywhere between 4 to 20 cmH2O. BiPAP machines can be adjusted in a lower or higher pressure setting range since they are designed for those with severe OSA, central sleep apnea (CSA), and other serious respiratory disorders.
What is a CPAP machine?
All three machines are forms of positive airway pressure therapy (PAP) and are designed for treating Obstructive Sleep Apnea (OSA). OSA is one of the three types of sleep apnea. A ll three acronyms describe machines that along with a CPAP mask and tubing provide a gentle flow of pressurized, filtered air to keep your airway open. These three machines keep obstructions from blocking your ability to breathe when you’re asleep.
How long have CPAP machines been around?
CPAP machines have been around for over 40 years. CPAP machines were pioneered by an Australian doctor, Dr. Colin Sullivan, whose long-term research interests in the role of the upper respiratory airway in sudden infant death syndrome (SIDS) led him to discover that PAP therapy could also be used to treat sleep apnea.
What is an APAP?
An APAP is capable of adjusting pressures accordingly. You toss and turn during sleep. If you spend part of the night on your back and part on your side, your snoring and apnea events may change depending on your sleeping position.
What is the definition of apnea?
Most experts agree on the standard definition of an apnea as a reduction in airflow of at least 90%. Hypopneas are more subjective, since they occur when your airways partially collapse. As a result, there is no standard measurement for what counts as a hypopnea.
What is the most common sleep disorder?
Obstructive sleep apnea (OSA) is a common sleep disorder, believed to affect at least 2% to 4% of people 1. During sleep, people with OSA experience multiple partial or complete obstructions of the airway, termed hypopneas and apneas. Additional symptoms may include loud snoring, gasping or choking, and daytime sleepiness.
What is AHI in sleep?
The apnea-hypopnea index (AHI) is a diagnostic tool for determining the presence and severity of obstructive sleep apnea (OSA).
How long does apnea last?
The AHI also does not measure how long an apnea or hypopnea lasts; only that it occurs for at least 10 seconds. People with apneas lasting 30 seconds may experience greater consequences than people whose apneas last 10 seconds.
What does AHI stand for in sleep study?
If you have recently received a diagnosis of sleep apnea or taken a sleep study, you may have noticed an AHI reading on your results. AHI is short for apnea-hypopnea index 2. This is a scale doctors use when diagnosing obstructive sleep apnea (OSA).
What is the primary measure of OSA?
While the AHI is the primary measurement for diagnosing OSA, your doctor may review other metrics to better understand the severity of your OSA. For example, the oxygen desaturation index 6 (ODI) measures how many times per hour, on average, your blood oxygen levels fall below normal for 10 seconds or longer. Another important metric, especially for children, is the level of carbon dioxide in the blood. A high level of carbon dioxide may arise due to a long period of breathing at less than full capacity, even if the airway is not completely blocked.
How many events per hour can a child have sleep apnea?
Mild: Children with an AHI of one to five events per hour may be diagnosed with mild sleep apnea.

Diagnosis
Sleep apnea, also spelled sleep apnoea, is a sleep disorder in which pauses in breathing or periods of shallow breathing during sleep occur more often than normal. Each pause can last for a few seconds to a few minutes and they happen many times a night. In the most common form, this follows loud snoring. There may be a choking or snorting sound as breathing resumes. Because the disorder disrupts normal sleep, those affected may experience sleepiness or feel tired durin…
Treatment
People with sleep apnea have problems with excessive daytime sleepiness (EDS) and impaired alertness. OSA may increase risk for driving accidents and work-related accidents. If OSA is not treated, people are at increased risk of other health problems, such as diabetes.
Due to the disruption in daytime cognitive state, behavioral effects may be present. These can include moodiness, belligerence, as well as a decrease in attentiveness and energy. These effec…
Clinical Trials
Sleep apnea can affect people regardless of sex, race, or age. However, risk factors include:
• being male
• obesity
• age over 40
• large neck circumference (greater than 16–17 inches)
Lifestyle and Home Remedies
When breathing is paused, carbon dioxide builds up in the bloodstream. Chemoreceptors in the bloodstream note the high carbon dioxide levels. The brain is signaled to awaken the person, which clears the airway and allows breathing to resume. Breathing normally will restore oxygen levels and the person will fall asleep again. This carbon dioxide build-up may be due to the decrease of output of the brainstem regulating the chest wall or pharyngeal muscles, which cau…
