Summary
Artero-venous difference and cardiac output have been investigated on two healthy subjects at work and related to the oxygen consumption.
The A-V difference in oxygen has been found to be approximately a linear function of the energy consumption; cardiac output is, therefore, an hyperbolic function of metabolism.
Cardiac stroke volume increases somewhat with increasing metabolism: a further increase of metabolism, from ab. 1/3 of the maximum, takes place without a further increase of the stroke volume.
