Reliability of the Samsung Galaxy for the Detection of Moderate to Severe Obstructive Sleep Apnea

April 11, 2026 updated by: Robson Capasso, Stanford University
The study will test the reliability of the Samsung Galaxy for the Detection of Moderate to Severe Obstructive Sleep Apnea (OSA)

Study Overview

Status

Completed

Detailed Description

A prospective cohort of 150 individuals 22 years or older with a prior diagnosis or with a high likelihood of having moderate to severe OSA, screened using STOP-Bang and Epworth Sleepiness Scale questionnaires will be recruited and will utilize the Samsung Galaxy Watch technology to monitor sleep patterns, oxygen saturation, PPG, and heart rate variability amongst other physiologic parameters. All data will be collected over the course of two intervention nights in the sleep lab and at home for three nights.
