A method for treating obstructive sleep apnea in a patient by electrical stimulation of muscles of the upper airway includes detecting an obstructive apnea and then stimulating muscles of the upper airway in response to the apnea. The apnea is detected by monitoring changes in a respiratory effort waveform of the patient for a parameter characteristic of the patient\s level of respiratory effort which is averaged over successive respiratory cycles to provide a baseline average. A limit value is then generated from the baseline average and the value for the parameter is compared with the limit value. If the limit value is exceeded, an apnea event is detected. Electrical stimulation can then be applied to a muscle of the upper airway upon detection of the apnea at a level which restores patency to the airway.

A method for treating obstructive sleep apnea in a patient by electrical stimulation of muscles of the upper airway by the steps of: (a) detecting an apnea by the steps of: (1) monitoring a respiratory effort waveform for a parameter characteristic of the patient\s level of respiratory effort; (2) averaging a plurality of values of the parameter taken from successive respiratory cycle, said average providing a baseline average for the parameter; (3) generating a limit value from the baseline average; (4) comparing a value of the parameter with the limit value; and (b) applying electrical stimulation to the muscles of the upper airway upon detection of the apnea at a level which restores patency in the airway wherein the parameter is a peak amplitude of the waveform.
