Figure 18-7
Illustration demonstrating the principle of determination
of cardiac output according to Fick's equation. If the O2
concentration
of the pulmonary artery (CpaO2
), the O2
concentration of the pulmonary vein (CpvO2
),
and O2
consumption are known, cardiac output can be calculated. (From
Berne RM, Levy MN: The cardiac pump. In Cardiovascular
Physiology, 8th ed. St Louis, CV Mosby, 2001, pp 55–82.)
