We compared the effects of sustained isocapnic hypoxia (SIH; 20 min) and repetitive isocapnic hypoxia (RIH; 10 2-min episodes) on ventilation (VI), genioglossal (EMGgg) and diaphragmatic electromyographic (EMGdi) activities, and supraglottic airway resistance in 11 normal supine male subjects (36.6 +/- 2.2 yr) during wakefulness. Seven of the subjects had control measurements on a separate day. Desaturation was similar (arterial O2 saturation 80-84%) in the SIH and RIH protocols. SIH and RIH… CONTINUE READING
