Abstract

Single-breath washout of two inert gases (He and SF6) in anesthetized mechanically ventilated dogs in normal conditions with the heart beating and during reversible heart arrest revealed no effects attributable to the action of the beating heart. It is concluded that in the conditions of the experiments convective mixing by the cardiac action played an insignificant role in promoting intrapulmonary mixing and transport.

摘要

在正常条件下心脏跳动以及可逆性心脏停搏期间，对麻醉状态下机械通气的犬进行两种惰性气体（氦气和六氟化硫）的单次呼吸冲洗，结果显示未发现与心脏跳动作用相关的影响。得出的结论是，在实验条件下，心脏活动引起的对流混合在促进肺内混合和传输方面作用不显著。
