Checkme O2 Max 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 Checkme O2 Max 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 Checkme O2 Max while you sleep, and it will quietly collect data, providing a 98% effective detection rate for sleep apnea.
Checkme O2 Max is a wearable blood oxygen saturation monitoring device that can track various vital signs including blood oxygen saturation levels, heart rate, respiratory rate, and sleep data. It is a portable device that can be used anytime, anywhere, and the collected data can be transmitted to a smartphone or computer for further analysis.
