Home-based monitoring and alert system for Sleep Apnea patients

Obstructive Sleep Apnea (OSA) is a very common sleep disorder which affects a significant portion of the population. The gold standard for monitoring OSA, and the treatment efficacy is through a Polysomnogram (PSG). A PSG measures a multitude of biological signals to determine the severity of OSA. However, a PSG is expensive, and causes discomfort for the patients. The proposed system allows for home-based monitoring that is affordable and much more comfortable for the patient than the conventional PSG. It makes use of 3 biological signals including a single channel frontal electroencephalogram (EEG) from the FP2-A1 positions, blood oxygen saturation (SpO2) reading, and recording of snores. In the proposed system, every individual event is logged into a locally stored file, and if there are at least 2 OSA events happening at the same time, the OSA episode is deemed serious and a buzzer will sound to wake the patient. A message is also sent to the caregiver / next-of-kin to notify them.
