| 摘 要： | 通过自行设计实验装置对CO_2重复呼吸法施行了改进(MCRT),其目的是能够在不间断的运动中连续地间插测定心输出量(Q)。为了检验它的实效性,我们用MCRT和超声心动图法(ECGT)进行了运动中Q的同步测定,结果二者呈高度相关(r=0.92,P<0.01)。

| Abstract: | Carbondioxide rebreathing technique with some modification was applied to the continuous measurement of cardiac output during exercise without intervals. For examining its validity sake, cardiac output was tested by carbondioxide rebreathing technique and echocardiography technique simultaneously in the study. The result showed that significant correlation existed between the two methods. Carbondioxied rebreathing technique therefore, can be used to determine cardiac output during exercise. |
