Sleep apnea is a chronic disorder characterized by inability to maintain adequate ventilation during sleep due to sleep-related increase in upper airway resistance, while breathing during wakefulness is satisfactory.
Sleep apnea is a type of sleep disordered breathing where people repeatedly stop breathing during sleep. It affects up to 25% of adults in the US.
An “apnea” is a temporary cessation of breathing.
People with sleep apnea repeatedly have issues with their breathing during sleep, 5-15 times per hour in mild cases or up to hundreds of times per night in severe cases. The loss of airflow lowers the blood oxygen, triggering the brain to wake up. People with sleep apnea might not notice, or they might wake up gasping.
The difficulty breathing during sleep could be caused by the airway falling closed and blocking air from flowing (obstructive sleep apnea) or, less commonly, by the brain not sending the signal to breathe (central sleep apnea). Both types keep people from falling into the deep sleep that the body needs, and puts a strain on long-term health.
Sleep apnea symptoms vary by person and may include:
A healthcare provider will ask questions about symptoms and sleep, ideally with the help of a partner or roommate, if available.
Sleep apnea is assessed with a sleep study, which uses stick-on sensors to measure things such as breathing, heart rate, brain activity, and body movements while asleep. The study can be done during an overnight stay in a sleep center/lab (called polysomnography) or at home. Home testing collects less information but may be more convenient for straightforward cases. A healthcare professional can help decide which is best.
There are several treatments for sleep apnea, and people may try multiple options or a combination to find one that works for them.
CPAP is the most common treatment for sleep apnea. A CPAP machine is a device that pumps air through a mask to help the throat stay open while sleeping. There are many different shapes and sizes of masks to fit different faces.
For milder cases, an oral appliance (also called a mandibular advancement device), similar to a mouth guard, helps keep the airway open by moving the jaw forward.
Positional therapy is helpful for people who mostly experience apneas while lying on their back. Devices that buzz when you roll on your back, or a wearable cushion that keeps you sleeping on your side are some examples of positional therapy.
Surgery to widen the airway, usually involving the nose, tongue, palate, or jaw.
Hypoglossal nerve stimulation involves a small device implanted in the chest wall that triggers muscles to keep the airway open and continue breathing (about the size of a pacemaker).
Medications may be prescribed to help people stay awake if they are still having difficulty despite other treatments such as CPAP.
Helpful lifestyle changes could include keeping healthy sleep habits, developing a regular movement practice, avoiding alcohol before bed, and quitting smoking.
CBT can help to keep healthy sleep habits and adapt to and stick with CPAP or other treatment options.
Connecting with other people who have sleep apnea can empower people to cope and learn strategies to manage symptoms and treatments.
