摘要
运动心肺功能试验是 指在运动负荷下对受试者的心肺功能进行联合测定和综合评估。其生理基础为心肺耦联转运氧和二氧化碳所介导的细胞线粒体内的氧化反应,为运动提供能量。肺部病变时,心肺耦联异常引起氧转运能力减退,无氧运动提前出现,致运动中能量代谢、肺功能和心功能异常。因此,运动心肺功能试验可为肺部疾病病人心肺功能的联合评价、劳动能力的评估、康复方法的选择、呼吸困难的鉴别诊断、呼吸系疾病的早期诊断、手术适应证的选择等提供依据。
Cardiopulmonarv exercise
test is performed to measure and assess the cardiopulmonary function of subjects during exercise. Its physiological basis is that the en-ergy repuired during exercise is supplied by ox-idation in mitochondria, which depend on transport of oxygen and carbon dioxide performed by cardiopulmonary chain. In the pa-
tients with lung diseases, the metabolism and cardiopulmonary function are abnormal during exercise because lung diseases cause dys-function of cardiopulmonary chain, resulting in disability of transport of oxygen. So, cardiopulmonary exercise test can provide evidence for the assessment of cardiopulmonary dysfunc-tion, evaluation of labor ability, choice of reha-bilitation program, differentiation of dyspnea, early diagnosis of lung disease and choice of indication for pneumonectomy.
