Apple Watch vs. Oura Ring for Sleep Apnea
Key Takeaways
• The Apple Watch and the Oura Ring can track changes in breathing patterns, blood oxygen levels, heart rate, and sleep stages. These changes are associated with sleep apnea.
• Both devices can play a supportive role in helping identify patterns that may indicate a need for further evaluation.
• Neither device is a substitute for a sleep study completed by a medical professional.
Wearable devices to track health metrics have gained traction over the last decade. The devices provide fitness tracking and monitor certain measurable health parameters, such as sleep. They may be especially of interest to those concerned about sleep apnea.
Two devices talked about include the Oura Ring and the Apple Watch. But can these wearables help detect sleep apnea, or do they only provide a hint to sleep disturbances? The article below examines the Apple Watch versus the Oura Ring through a sleep apnea lens.
What Can the Oura Ring Detect About Sleep Apnea?
The Oura Ring is a smart ring that tracks sleep and overall health using advanced biometric sensors. When it comes to obstructive sleep apnea (OSA), the ring measures certain sleep metrics that may suggest issues associated with OSA. For example, the Oura Ring can measure:
Breathing patterns: The Oura Ring can estimate breathing patterns. This can help identify frequent breathing irregularities, which may indicate a sleep disorder.
Blood oxygen level: Your blood oxygen, shown as SpO2, is the percentage of oxygen your red blood cells carry from your lungs to the body. The Oura Ring measures your average SpO2 during sleep. People with sleep apnea may experience low oxygen levels. If the ring detects low oxygen levels overnight, this hints at sleep apnea or another sleep disorder.
Restless sleep: The ring users signs, such as changes in heart rate and movement, to estimate when you're moving from sleep to wakefulness. Frequent occurrences of wakefulness may indicate a problem with sleep efficiency or suggest sleep apnea.
Heart rate: The Oura tracks heart rate. Periods of apnea may change heart rate patterns. Identifying significant fluctuations in heart rate can provide a clue as to whether a breathing disorder is present.
Sleep trends and scores: The ring analyzes sleep stages and estimates REM, light, and deep sleep, as well as total sleep time. It can indicate poor sleep quality, a sign of sleep apnea.
What Can an Apple Watch Detect About Sleep Apnea?
The Apple Watch is a smartwatch that provides health monitoring, which may help detect sleep apnea, including:
Breathing changes: The Apple Watch tracks subtle wrist movements caused by chest expansion during breathing. Changes in the motions may indicate interruptions in breathing.
Blood oxygen levels: Some Apple Watch models measure overnight oxygen saturation. Repeat decreases in oxygen level are associated with sleep apnea.
Heart rate and heart rate variability: Heart rate variability is the variation in time between each heartbeat. Apnea episodes can alter heart rate variability.
Sleep stages: The watch tracks sleep stages, including REM, light sleep, and deep sleep. It does not measure brain waves like a study in a sleep lab. Instead, it estimates sleep stages using other measurements, including heart rate variability, breathing changes, and movement.

How Both These Devices Help Sleep Apnea
Both devices can provide clues that sleep disturbances are occurring and may indicate sleep apnea. Although not all disturbances and sleep disorders are related to sleep apnea. It is still helpful to identify changes in breathing, heart rate, or oxygen level, which may suggest a problem.
Neither the Oura Ring nor the Apple Watch can directly measure air flow into the lungs or diagnose obstructive sleep apnea.
But by monitoring certain factors associated with sleep apnea, it may prompt someone to have further testing to confirm a diagnosis. The devices help you track trends in your sleep, including sleep stages and frequent awakenings. Essentially, both devices can serve as early warning tools.
Thoughts on the Apple Watch and Oura Ring for Sleep Apnea from a Respiratory Therapist
As a respiratory therapist, the first step in a proper diagnosis is for an individual to seek medical evaluation. Neither the Apple Watch nor the Oura Ring can provide the same diagnostic test and evaluation as is done through a sleep study in a controlled medical environment.
However, wearables, such as the Apple Watch and the Oura Ring, may prompt someone to seek clinical evaluation sooner, leading to a proper diagnosis and appropriate treatment. All in all, wearables are a valuable tool when used correctly and not relied on solely to make a diagnosis.
Conclusion
The Apple Watch and the Oura Ring can track important biometric factors associated with sleep disorders, including sleep apnea. These trends can alert users to a problem, prompting them to seek further evaluation.
A proper diagnosis is the first step in effectively treating obstructive sleep apnea. You can get tested for sleep apnea in the comfort of your own home using Sleep Care Online's Complete Care process - a white-glove, customized treatment from start to finish.
CPAP therapy remains the gold standard and can help prevent sleep apnea-related complications. It is vital to buy your CPAP machines, masks, and accessories from a company you can trust. Visit The CPAP Shop to purchase your CPAP machines, masks, and accessories!
