Abstract
Pulmonary capillary blood flow was measured by the nitrous oxide body plethysmograph technique in 16 patients, 10 of whom had scoliosis and six neuromuscular weakness. A linear correlation was found between the pulmonary artery to capillary flow conduction time and Pao (r=+0·85; p<0·001). The finding of a reduced flow conduction time and its correlation with the Pao suggests the presence of pulmonary arterial hypertension presumably on the basis of active vasoconstriction.
摘要
采用氧化亚氮人体体积描记法对16例患者的肺毛细血管血流量进行了测量，其中10例患有脊柱侧弯，6例患有神经肌肉无力。发现肺动脉至毛细血管血流传导时间与动脉血氧分压（Pao）之间存在线性相关性（r = +0·85；p<0·001）。血流传导时间缩短及其与动脉血氧分压的相关性表明可能存在基于活性血管收缩的肺动脉高压。
