A multisensor detector of a sleep apnea for using at home

Diagnosis of obstructive sleep apnea usually involves polysomnographic analysis, which unfortunately requires overnight stay in a specialized clinic and is very uncomfortable for a patient. This paper describes the method and apparatus for recording a set of signals to detect sleep apnea. The device records the following signals simultaneously: three-channel ECG, respiratory functions, signals from the accelerometer, and snoring sounds. Measurements are carried out during the night, in the patient´s home. Algorithm for automatic analysis of the data can be used to detect sleep apnea and hypopnea.
