Continuous physiological monitoring for sleep apnea detection, is usually achievable by body-attached mechanical sensors, body-attached electrodes, or remote ultrasound sensors. With current systems the user has 15 wires and tubes connected to his body. The main pain-point sensor is the oronasal one that measure the air flow, hence the respiration. A sleep apnea event is when respiration is reduced during sleep.
When used at home, such bulky systems don’t allow natural sleep and generate false positives and negatives. All serious medical devices respect the American Academy of Sleep Medicine (AASM) who is followed by the sleep specialists and health insurances. The AASM issued its rules where sleep apnea detection devices can be simplified, cheaper and easier to access to.
