目的探讨阻塞性睡眠呼吸暂停低通气综合征(OSAHS)患者运动心肺功能的改变及其可能机制。方法OSAHS患者30例为试验组,健康男性18名为对照组。受试者进行心肺运动试验(CPET),测定最大摄氧量占预计值百分比(.Vo2m ax占预计值%)、摄氧量功率比值(.VO2/WR)、氧脉搏占预计值百分比(.Vo2/HRm ax占预计值%)、无氧阈与最大摄氧量比值(AT/.Vo2m ax)、二氧化碳通气当量(.VE/.VCO2)及呼吸储备(V.
Objective To investigate the changes of cardiopulmonary function in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) and its possible mechanism. Methods Thirty patients with OSAHS were selected as experimental group and 18 healthy male controls as control group. Subjects underwent cardiopulmonary exercise testing (CPET), determining the percentage of predicted maximum oxygen uptake (.Vo2m ax in predicted value), oxygen uptake power (.VO2 / WR), and percentage of predicted value of oxygen pulse. Vo2 / HRm ax% predicted), the ratio of anaerobic threshold to maximal oxygen uptake (AT / .Vo2m ax), carbon dioxide ventilation equivalent (.VE / .VCO2), and respiratory reserve (V.
