Cardiovascular effects of periodic occlusions of the upper airways in dogs.

Abstract

Hypoxemia and decreased intrathoracic pressure have been postulated as contributing causes of cardiovascular morbidity in obstructive sleep apnea syndrome (OSAS). Because of the difficulty of manipulating experimental conditions in humans, we developed an anesthetized closed-chest dog model, simulating the periodic airway occlusions of OSAS by periodic… (More)
