Abstract
A method and device for detecting arousal from sleep in a patient by monitoring a respiratory effort waveform of the patient. At least one parameter of the waveform that is characteristic of a body movement artifact is monitored and compared with a predetermined limit. This method of arousal detection is particularly useful for treating sleep apnea by bursts of electrical stimulation in response to sensed inspiration since it allows the electrical stimulation to be reduced or stopped promptly as the patient wakes.
