Evidence for reflex upper airway dilator muscle activation by sudden negative airway pressure in man.

Abstract

1. To determine if negative upper airway pressure causes reflex pharyngeal dilator muscle activation, we used intra-oral bipolar surface electrodes to record genioglossus electromyogram (EMG) activity in response to 500 ms duration pressure stimuli of 0, -2.5, -5, -15, -25 and -35 cm H2O (0-90% rise time less than 30 ms) in ten normal, conscious, supine… (More)
