Summary
Method and system for automatic diagnosis of sleep apnea in the home environment. The system uses pressure sensitive sensors placed underneath a mattress and an algorithm to classify the severity of sleep apnea.
Technology Overview
This in-home system to diagnose sleep apnea saves the patient from having to spend a night in a sleep clinic attached to numerous sensors and wires. In the comfort of their own home, patients will put a rectangular metal plate with attached load cell sensors under their mattress. During the course of the night, these sensors record respiration rate, breathing, and movement. Recordings of patient data are analyzed using signal processing and machine learning algorithms to identify sleep apnea severity.
