Basic Principles and Technique

Disorders of sleep are common and often respond well to treatment. Polysomnography is important in diagnosing and characterizing such disorders. It involves recording the EEG on two or a few channels to characterize the stage of sleep while recordings are also made of eye movements, mentalis muscle activity (chin EMG), electrocardiogram, respiration, and oxygen saturation. Respiratory movements are recorded by measurement of air flow through the nasal passages and the mouth using thermistors and by recording thoracoabdominal excursions with surface electrodes. Oxygen saturation is measured using an ear oximeter. A microphone can be taped to the face to record snoring.
