Evaluation of Use of Wearable Sensor Garment in Home Screening for Sleep Apnea Events

Sleep apnea is a condition commonly characterized by frequent breaks in breathing during sleep, resulting degradation in sleep quality. This paper presents results of clinical trials aimed at evaluating the use of a wearable sensor garment for in-home screening of obstructive sleep apnea and hypopnea (OSAS). The garment used in this study included ECG, position and respiration sensors. Data from the garment sensors were compared to the signal collected during an overnight routine polysomnograph (PSG) in a sleep clinic. The obtained results showed that there is a comparable performance of the garment measurements and PSG measurements. Therefore, it was concluded that it is possible to use the wearable sensor garment in an in-home screening system to observe and monitor sleep apnea events.
