SleepU continuously monitors blood oxygen saturation (SpO2) and heart rate to help detect sleep apnea. When sleep apnea occurs (a pause or stop in breathing), oxygen levels drop. The SleepU detects this drop in oxygen saturation and heart rate changes, alerting the user with a vibration. When this happens repeatedly, the device records all the data, which can be reviewed in the app to help identify potential sleep apnea issues.
Wear our SleepU while you sleep, and it will quietly collect data, providing a 98% effective detection rate for sleep apnea.
