Comparison of the response of diaphragm and upper airway dilating muscle activity in sleeping cats.


The steady state and transient effects of hyperoxic hypercapnia on the electromyographic activities of the genioglossus (GG), posterior cricoarytenoid (PCA), and diaphragm (D) were studied in cats instrumented with chronically implanted electrodes during non-rapid eye movement sleep. Hypercapnia (inhalation of 3.4 and 7.4% CO2 in O2) increased the phasic… (More)
