Summary
This study checks if a Withings smartwatch can accurately detect sleep apnea compared to a full hospital sleep test. About 220 adults who are already scheduled for a sleep test will wear the watch overnight. The goal is to see if the watch can help screen more people for sleep apnea, which often goes undiagnosed.
