Question

Quizplus · Accepted Answer

The ECG, which measures heart rate, is used to detect cardiac rhythm disorders, and the pulse oximeter is used to determine arterial oxygen saturation, which indicates adequacy of ventilation. The EOG, which records eye movements, and the EMG, which records muscle movement, will also be attached. During REM sleep, the eyes move rapidly, but the muscles are paralyzed. Periods during which the EOG recorded lots of movement, and the EMG recorded very little, would indicate REM sleep. An actigraph device will be placed on the wrists and ankles to measure body motion for obtaining objective measurements of sleep duration.
