Title: SCREENING SYSTEM FOR ASSESSING SLEEP ABNORMALITIES
Abstract:
A home screening method for assessing whether a person is in need of a full sleep study in a sleep lab or is in need of immediate treatment for apnea and/or hypopnea. In carrying out the method, a screening service company provides a customer with a PVDF air flow sensor and an electronics module that connects to the sensor for filtering the sensor analog waveform due to temperature changes upon inspiration and expiration and due to mechanical stress due to snoring. The filtered signals are converted to a digital representation and stored during a period of sleep. The electronics module is then returned to the screening service where the stored information is analyzed in accordance with a program run on a host computer to identify the type, frequency, duration of detected events, The program further generates a report with recommendations for further action.
