摘要:
A method of detecting the occurrence of snoring by a patient is disclosed. The method comprises the steps of: (i) measuring a noise level with a sensor during an inspiration phase of the patient's breathing cycle; (ii) measuring a noise level with a sensor during an expiration phase of the patient's breathing cycle; (iii) using a processor to calculate a snore value as a function of the difference in the noise levels measured during the inspiration phase and the expiration phase; (iv) determining that snoring has occurred when the snore value is above a predetermined threshold; and (v) generating a snore signal to indicate that snoring has been detected.
