You can wear Apple Watch to bed and track breathing disturbances while you're sleeping (on supported models), which can be used in an algorithm to detect signs of moderate to severe sleep apnea. Each day you're given an elevated or not elevated assessment for your breathing disturbances for the night before.
Researchers then compared how well the watch performed to the measures taken during the sleep study. In general, Apple's testing found that the watch picked up on any degree of sleep apnea about 66% of the time.
The Galaxy Watch 7 competes with Apple introducing their own sleep apnea detection functionality. Using the Samsung health monitor app, the Galaxy watch tracks sleep over a 10-day period to determine patterns of sleep apnea.
The FDA has approved Apple's sleep apnea detection feature. Sleep apnea is a sleep disorder that causes a person's breathing to repeatedly stop and start throughout the night. The feature is designed for the Apple Watch, and it works by analyzing a new metric that the company calls "breathing disturbances."
The Apple Watch's Breathing Disturbances feature monitors your respiratory patterns to determine if your breathing is “elevated” or “not elevated.” Consistent “elevated” breathing is a key indicator for sleep apnea.
Severe obstructive sleep apnea means that your AHI is greater than 30. You have more than 30 episodes per hour. Moderate obstructive sleep apnea means that your AHI is between 15 and 30.
Apple Watch Series 9, Apple Watch Series 10, and Apple Watch Ultra 2 now offer a feature to help identify signs of sleep apnea.
In some cases, sleep apnea can resolve if you return to a healthy weight, but it can recur if you regain the weight. Exercise. Regular exercise can help ease the symptoms of obstructive sleep apnea even without weight loss. Try to get 30 minutes of moderate activity, such as a brisk walk, most days of the week.
Do you know how often you snore? Or how loud it is when you do? With SleepWatch Snore Tracking, all SleepWatch users are able to record, listen to, and track their snoring from their Apple Watch or iPhone. You can now listen to your top snores and track where your snoring ranks on a scale from minimal to heavy.
At-home sleep apnea testing is an easy, cost-effective way to figure out whether you're having trouble breathing. A home sleep apnea test is a very simplified breathing monitor that tracks your breathing, oxygen levels, and breathing effort while worn.
The ApneaLink Air is capable of recording up to five channels of information to assist with your diagnosis: respiratory effort, pulse, oxygen saturation, nasal flow and snoring.
Snoring, snorting or gasping: Noisy sleep is a warning sign that your upper airway might be obstructed. Not all snorers have apnea, but the two often go hand-in-hand. As snoring gets louder, chances of having sleep apnea are greater and greater.
REM sleep is characterized by relaxed muscles, quick eye movement, irregular breathing, elevated heart rate, and increased brain activity. Most adults need about two hours of REM sleep each night. REM sleep plays a role in memory consolidation, emotional processing, brain development, and dreaming.
A diagnosis of obstructive sleep apnea is based on the results of the polysomnogram and the presence or absence of certain symptoms. A polysomnogram records how many apneas, hypopneas, or respiratory effort-related arousals (RERA) occur per hour while a person is asleep.
While sleep apps can provide valuable insights into your sleep patterns, they do have limitations. One of the main limitations is that they cannot provide a definitive diagnosis of sleep apnea.
The weighted overall sensitivity was 66.3% (95% CI, 62.2-70.3) and the weighted overall specificity was 98.5% (95% CI, 98.0-99.0). According to the FDA, Apple's Sleep Apnea Notification Feature is not intended to diagnose, treat, or aid in the management of sleep apnea.
The Sleep Apnoea Notifications Feature is not intended to diagnose, treat or aid in the management of sleep apnoea. Not all people with sleep apnoea will receive a notification. If you believe you have sleep apnoea, talk to your doctor.
Your CPAP Pressure Needs Adjusting
If the setting is too high, you may struggle to exhale and find yourself waking in the middle of the night. If the setting is too low, you might continue to have frequent breathing gaps and wake up in the morning feeling tired. Finding the right setting can take trial and error.
In general, Apple's testing found that the watch picked up on any degree of sleep apnea about 66% of the time. It was more accurate at detecting severe bad sleep apnea, correctly alerting users about 89% of the time. It correctly alerted users to moderate breathing problems about 43% of the time.
