Abstract

A portable or wearable system for monitoring and diagnosing sleep disorders, such as sleep apnea, and an associated method of monitoring and diagnosis. The device which can be used for the detection, assessment, diagnosis and pre-diagnosis (screening) of sleep apnea, as well as other sleep-related disorders associated with sleep apnea, such as hypopnea, snoring and abnormal cardiac rhythms. The device preferably samples, stores and records sound at a frequency of 1000 Hz and higher to allow for an accurate analysis of the subject'"'"'s condition to be carried out. Memory is provided in the device to store at least six hours of continuous data. Data collected by the device can be downloaded to an external computing device for later use and analysis by a medical professional.
