Arousal Analysis by Pulse Wave Amplitude in Patients With Obstructive Sleep Apnea

NCT01690429 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 26

Summary

Photoplethysmography is an easy non-invasive method to detect the pulse wave amplitude (PWA) from a finger. This can be measured using the Somnocheck micro system. A pulse wave amplitude decrease (PWAD) is considered to be a marker for autonomic activation. Detecting the PWAD is a surrogate marker for waking reactions (arousal) which eventually will contribute to assess sleep disruption and resulting performance deterioration. Arousal and performance deterioration and its possible improvement under continuous positive airway pressure (CPAP) therapy will be determined in this study.

Conditions

Interventions

DEVICE

Somnocheck micro

Study nights in sleep lab with standard polysomnography plus Somnocheck micro. The Somnocheck micro is a device with pulse oxymetry and nasal cannula, which can be worn like a wristwatch. It records information about sleep disordered breathing, oxygen saturation, and pulse wave.
