低氧性肺血管收缩的机制Euler和Liljestrand在34年前开创了对肺循环了解的一个新阶段。他们证实,吸入低氧的混合性气体可引起肺血管收缩。目前已很清楚,当肺泡PO_2值降低到60mmHg以下时,肺小动脉呈现明显的收缩,并且肺血管收缩范围的大小与低氧区域的分布相一致。关于低氧引起肺血管收缩的机制已进行过大量研究。近年来Fishman和Bergofsky对低氧
Mechanism of Hypoxia Pulmonary Vasoconsation Euler and Liljestrand pioneered a new phase of pulmonary circulation 34 years ago. They confirmed that inhaled hypoxia mixed gas can cause pulmonary vasoconstriction. It is now clear that when the alveolar PO_2 decreased to below 60mmHg, pulmonary arterioles showed significant contraction, and the size of pulmonary vasoconstriction consistent with the distribution of hypoxic regions. A great deal of research has been done on the mechanism of hypoxia causing pulmonary vasoconstriction. In recent years Fishman and Bergofsky on hypoxia
