Abstract
The results secured by the simple method of estimating cardiac output, described in the previous paper, have been applied to data already in the literature. Hundreds of comparisons are possible between estimates of cardiac output made by our blood pressure method from values given by the authors, and the results of estimates of cardiac output by some other well known method employed at the same time. The correlations between the results secured by our method and those obtained by Fick, acetylene, ethyl iodide, and nitrous oxide methods are often surprisingly good. There is an unexplained difference in level between the Fick and blood pressure estimates, but not between the blood pressure estimates and those of the three older methods.Keywords
