SleepU Sleep Pulse Oxygen Monitor

Did you know that one in five adults who snore can suffer from obstructive sleep apnea (OSA)? This can cause you to take in less than optimal amounts of oxygen lowering your blood oxygen levels and interrupting your sleep! If you feel tired through your day even though you think you spent for a healthy (7-9 hours a night) amount of time that night, you could be suffering from these sleep interruptions.

Since our nightly sleep cycle circulates from light to deep, REM sleep, interruptions can wake you enough to restart your natural sleep cycle. This leads to not enough REM sleep. The exact number of sleep disturbances is hard to determine without a sleep monitoring device.

The Wellue SleepU is a sleep monitor that you wear overnight to track your oxygen levels and heart rate. SleepU is a highly accurate and FDA registered device listed as a Class II medical device.


Traditional SpO2 sleep sensors have a "Duckbill" design that attached to the tip of your finger. The flaw in this design is that is can easily come off your figure during the night. This type of design also does not allow free movement of your finger.
