We recently showed that the glottis is actively closed throughout post-hyperventilation, hypocapnic central apnea in lambs. The present study was designed to test whether the glottis is also closed in non-hypocapnic central apnea. Twenty-seven lambs aged 2 to 30 days were intravenously injected with 325 mg of sodium pentobarbital, so as to obtain breathing(More)
We recently showed that hypoxia does not induce active expiratory glottic adduction in awake lambs more than 10 d old. To reconcile our results with previous data from other researchers, we hypothesized that an active expiratory glottic closure might still be part of the response to hypoxia in the very first postnatal days. The present study was undertaken(More)
