在5只幼猪（每只7-9 kg）中，使用吸入氟烷浓度的正弦强制函数获得有效肺灌注的数据。这些数据与直接Fick法测得的心输出量进行了比较，并对静脉混合进行了校正。为了在每个实验期间产生不同水平的心输出量，改变呼吸和循环条件。对于一起进行的5个实验，非侵入性获得的有效肺灌注与静脉混合物校正的Fick数据之间的比率的平均值为0.01（SD = 0.14，n = 55），r = 0.92。
In 5 young pigs (7-9 kg each) data on effective lung perfusion were obtained using a sinusoidal forcing function in the inspired halothane concentration. These data were compared with the cardiac output measured by the direct Fick method for O2, corrected for venous admixture. To produce different levels of cardiac output during each experiment the respiratory and circulatory conditions were changed. For the 5 experiments taken together, the mean of the ratios between the non-invasively obtained effective lung perfusion and the venous admixture corrected Fick data was 0.01 (SD = 0.14, n = 55) with r = 0.92.
