Abstract
Polysomnography (PSG) or home sleep apnea testing (HSAT) are the current standard diagnostics for sleep apnea. These systems require a multitude of sensors and are obtrusive and thus not suited for long-term monitoring. Recent advances in optical heart rate monitoring at the wrist give promise for low-cost wearable devices suitable for the early detection and ambulatory monitoring of sleep apnea. Even though not expected to completely replace PSG or HSAT, such devices could allow for a reliable pre-screening over several nights in larger populations. We investigated the feasibility of replacing important PSG measurements (oxygen saturation, respiratory rate and cardiac interbeat intervals) using CSEM’s proprietary wearable device.
