• Loud Snorers Sleep Apnea Sufferers Asthmatic Patient COPD Pneumonia Pilots.

• O2Ring continuously monitors blood oxygen saturation (SpO2) and heart rate to help detect sleep apnea. When sleep apnea occurs (a pause or stop in breathing), blood oxygen levels drop. O2Ring detects this drop in oxygen saturation along with heart rate changes and alerts the user through vibration. When this happens repeatedly, the device records all the data, which can be reviewed via the app to help identify potential sleep apnea issues.
• Wear our O2Ring while you sleep, and it will quietly collect data, with a 98% effective detection rate for sleep apnea.
