Summary

In a subject rebreathing in a small bag, the rate of increase of Paco2 is, within a circulation time, linear function of PAco 2 itself; by graphical extrapolation of this function, experimentally obtained using a rapid CO2 meter, the CO2 pressure of mixed venous blood may be obtained; the values of PacO2 VO 2 R being determined, the values of A-V difference and therefore of cardiac output can be obtained.

The detailed experimental procedure is described.
