ABSTRACT:
Upon the detection of an appropriate apnea event, respirating gas supply apparatus according to various embodiments supply stimulus to the upper airway passages of an in vivo respiratory system in an effort to dislodge any occlusion or obstruction in the upper airway passages. In one embodiment the stimulus applied is a high pressure pulse of gas. In another embodiment an electrical signal is applied to an electromyographic electrode (270) positioned in proximity to a nerve controlling a muscle or organ which may obstruct the upper airway passage.
