Abstract

Adequate oxygen uptake by the lungs for prolonged apneic periods is possible even in the absence of respiratory movements provided that 100% O2 is applied at the airway opening. The mechanism by which adequate gas mixing takes place during this apneic respiration is not entirely clear. We propose that a major mechanism producing O2 uptake during apnea is the enhanced gas mixing secondary to airflow generated by the beating heart.

摘要

即使在没有呼吸运动的情况下，只要在气道开口处施加100%的氧气，肺部在长时间呼吸暂停期间仍有可能摄取足够的氧气。在这种呼吸暂停期间发生充分气体混合的机制尚不完全清楚。我们提出，呼吸暂停期间产生氧气摄取的一个主要机制是继发于心脏跳动产生的气流的气体混合增强。
