It is not stated that this study had approval from an institutional review board from the agency. The 19 male patients participated in overnight pre and postoperative non-invasive polysomnnographic studies (PSG). These tests include the Epworth sleepiness scale recording, CAM of upper airway, and bio-data recording. PSG entails electroencephalogram (EEG), submental electromyogram (EMG), anterior tibialis EMG, electrocardiogram (ECG), thoraco-abdominal motion, oronasal airflow (expired CO2), arterial oxygen saturation with pulse...
