Definition of Cardiac output

1. Noun. The amount of blood pumped out by the ventricles in a given period of time. "A resting adult has a cardiac output of about three quarts a minute"

Generic synonyms: Flow, Flow Rate, Rate Of Flow



Medical Definition of Cardiac output

1. A measurement of the blood flow through the heart to the systemic (and pulmonary) circulation. Cardiac output is expressed as volume of blood per unit time or litres/minute. Cardiac output can be calculated using the Fick method (oxygen consumption divided by arteriovenous oxygen difference) or by the thermodilution technique, using a Swan-Ganz catheter. (27 Sep 1997)
