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.
Claims21
Method for the ambulatory detection and diagnosis of sleep disorders in a patient, comprising
- sensing heart potentials and generating a heart rate signal,
- sensing respiratory sounds and generating loud breathing signal and a snoring signal from said respiratory sounds,
- sensing degree of oxygen saturation in the patient's blood and generating an oxygen saturation signal,
- storing said heart rate signal, loud breathing signal, snoring signal, and oxygen saturation signal over time as stored signals, and
- comparing said stored signals to determine whether each one of obstructive sleep apnea, central apnea, continuous snoring, upper airway resistance syndrome, and nocturnal myoclonus is present.
Apparatus for the ambulatory detection of physiological factors in a patient for use in diagnosing sleep disorders, comprising
- means for sensing heart potentials and generating heat rate signals,
- means for sensing respiratory sounds and generating a loud breathing signal and a snoring signal,
- means for sensing degree of oxygen saturation in the patient's blood and generating an oxygen saturation signal,
- means for storing said heart rate signal, loud breathing signal, snoring signal, and oxygen saturation signal over time, and
- means for comparing said stored signals to determine whether each one of obstructive sleep apnea, central apnea, continuous snoring, upper airway resistance syndrome, and nocturnal myoclonus is present.
