惰性气体再呼吸方法-无创伤测量心排出量(CO)的原理,早在1910年由丹麦的诺贝尔奖获得者AugustKrogh所描述,其基本原理和方法是病人在一个闭合呼吸系统中,反复呼吸微量溶血性气体,该气体被血液吸收灌注到肺,因此在呼吸装置中上述气体按指数速率与肺灌注成比例消失(如图1)。因此? The inert gas respiration method - the principle of non-invasive measurement of cardiac output (CO), was first described by August Krogh, a Danish Nobel laureate as early as 1910. The basic principle and method is that the patient breathe repeatedly in a closed respiratory system A trace amount of hemolytic gas, which is absorbed into the lungs by the blood, so that the above gases disappear exponentially in proportion to lung perfusion in the respiratory device (Figure 1). therefore?
