Apparatus for synchronized treatment of obstructive sleep apnea

摘要

A device is provided for stimulation of an upper airway muscle of a patient to relieve an airway obstruction in which stimulation is synchronized with the inspiratory phase of the patient's respiratory cycle. A respiratory effort waveform of the patient is monitored for a changes in slope and amplitude of the respiratory effort waveform characteristic of the inspiratory phase. Stimulation is then commenced and concluded according to the detected inspiratory phase. <IMAGE>
