Dr. Nauman Mushtaq, medical director of cardiology at Northwestern Medicine Central DuPage and Delnor hospitals. How useful are these sensors in smartwatches? The Withings ScanWatch Horizon is FDA-cleared for blood oxygen monitoring. While health sensors in smartwatches present promise in research, some experts are unsure how typically these sensors are being utilized in everyday circumstances.
