Abstract
The physiological parameters of heart rate, respiratory and snoring sounds, the degree of oxygen saturation of the blood, and the bodily position of the patient are measured and stored in coded form by means of portable apparatus. The stored data are transferred to a computer and then analyzed. The mobile apparatus comprises a detection and storage unit (2) and the following pickups: three EKG electrodes (3), one laryngeal microphone (4), an oximeter-finger sensor (5) and a position pickup (6). The apparatus permits an ambulatory diagnosis of sleep apnea which is comparable in its meaningfulness to diagnoses based on stationary sleep laboratory tests for sleep apnea.
