Wearable Sensor could be sed to Monitor Obstructive Sleep Apnea Treatment Response

A wearable pulse oximeter and connected software platform show promise for monitoring obstructive sleep apnea (OSA) and other sleep-related breathing diseases, according to research presented at the ATS 2025 International Conference.The device (pulse oximeter), which is cleared for medical use, was designed for comfort and ease of use; a clinical trial found high rates of utilization by patients. It could be used to track patient response to OSA treatment over time.Wearable sensors like the Oura ring and Apple Watch that measure biometrics during sleep are widely used by consumers, but are not cleared for medical use.At the same time, other medical devices used in sleep studies gather clinically relevant data, but are too cumbersome and costly to use for frequent monitoring.

The device connects to an app that users can access from their smartphone, giving patients access to a subset of the same data as their health care providers.The device was used in several different clinical settings, including to monitor patient response to a pharmacologic treatment program for OSA. During the monitoring study, patients were asked to wear the device for nine nights over a 47-day period.However, many patients voluntarily wore their devices more often, with 85% of patients using beyond the recommended nights. One patient used the device almost nightly for 44 days, the researchers noted.
