Abstract

In a method of diagnosing obstructive sleep apnea, snoring and respiration sounds made by a patient, as well as the patient's heart rate, are recorded while the patient is sleeping. Signals indicative of snoring sounds and the time intervals therebetween are produced from the respiration sounds and recorded, and a first respiration disturbance index representing the numbers of intervals per hour between episodes of snoring is calculated. Signals indicative of the patient's heart rate are likewise produced and recorded, and the average heart rate is calculated. A second respiration disturbance index representing the number of episodes per hour in which the patient's heart rate remained at 90 to 109% of its average rate is calculated. A physician can then evaluate the first and second disturbance indices to determine whether obstructive apnea is indicated.
Apparatus for practicing the method is also disclosed.
