[A simple expression of the intrapulmonary ventilation-perfusion ratio distribution curves].
We propose a method to express the intrapulmonary ventilation-perfusion distribution curves obtained by 6 inert gas elimination technique. A VA/Q distribution curve was obtained by calculating the amount of perfusion distributed in each fraction of the VA/Q as percentage of the cardiac output and then averaging them to obtain a single distribution curve. By this method, it is possible to simplify the representation of the distribution curve, to clarify the serial changes through the experiment, and further to compare different patterns in several experimental groups.
