OSA in Pregnant Women With Chronic HTN

WP200U, is a Type III, wrist-worn, FDA-approved home sleep testing device that utilizes finger plethysmography (peripheral arterial tone, oxyhemoglobin saturation and heart rate), actigraphy (movement), acoustic decibel detection (snoring volume), and accelerometry (body position) to help diagnose sleep-related breathing disorders (including snoring), and to give information about sleep stages and position during actual sleep time.
