A method is described of calibrating the Kofranyi-Michaelis (KM) respirometer under normal laboratory conditions using expired air from a subject exercising in the steady state. During the calibration procedure the KM is connected to the subject via a valve and respiratory tubing and placed in a large airtight Perspex box from which an outlet tube passes to a Douglas bag. Calibration is made by comparing during a given time the content and volume of expired air in the Douglas bag with that passing through the meter at several different exercise flow rates. An example of a typical calibration experiment is given.
描述了一种在正常实验室条件下，使用来自处于稳定状态下运动的受试者的呼出气体对科弗兰尼-米凯利斯（KM）呼吸计进行校准的方法。在校准过程中，KM通过一个阀门和呼吸管与受试者相连，并放置在一个大型气密有机玻璃箱中，从该箱引出一根出口管通向一个道格拉斯袋。通过在给定时间内比较道格拉斯袋中呼出气体的含量和体积与在几种不同运动流速下通过该仪器的呼出气体的含量和体积来进行校准。给出了一个典型校准实验的示例。
