Exercise Physiol. 44ftik 931-938, 1978. -Ten patients with daytime somnolence and obesity were found to have periodic airway occlusion (AO) during nocturnal sleep. The cyclical ventilatory pattern consisted of a series of regular inspiratory...
متن کاملComparison of blood pressure measurements on the upper and lower extremities during spinal anesthesia
Introduction: During spinal anesthesia, measurement of blood pressure is often obtained by an indirect method using an inflatable cuff on the upper arm. The relationship between the blood pressure measurements at the two sites in patients undergoing spinal anesthesia is unclear. This study was designed to evaluate the difference observed in systolic blood pressure (SBP) taken from the upp...
متن کاملEffect of upper airway negative pressure on inspiratory drive during sleep.
To determine the effect of upper airway (UA) negative pressure and collapse during inspiration on regulation of breathing, we studied four unanesthetized female dogs during wakefulness and sleep while they breathed via a fenestrated tracheostomy tube, which was sealed around the permanent tracheal stoma. The snout was sealed with an airtight mask, thereby isolating the UA when the fenestration ...
متن کاملCritical closing pressure during midazolam-induced sleep.
The critical closing pressure (Pcrit) is the airway pressure at which the airway collapses and reflects the anatomical contribution to the genesis of obstructive sleep apnea. Pcrit is usually determined during non-rapid eye movement sleep at night, but has been determined under midazolam sedation during the day in the absence of sleep stage monitoring. Indeed, little is known about the effects ...
متن کاملControl of Upper Airway Motoneurons During REM Sleep.
The loss of tone in upper airway muscles contributes to disorders of breathing during sleep. In an animal model of rapid eye movement sleep atonia, decrements in the activity of upper airway motoneurons are caused by withdrawal of excitation mediated by serotonin and other transmitters, rather than by state-dependent inhibition.
