What is the average cardiac output at rest

Cardiac Output CO Cardiac output is the volume of blood the heart pumps per minute. Cardiac output is calculated by multiplying the stroke volume by the heart rate.

Stroke volume is determined by preload , contractility, and afterload. Cardiac output is important because it predicts oxygen delivery to cells. See also: Preload and Afterload — What's the Difference?

However, SV can increase when there is an increase in HR during exercise for example when other mechanisms are activated, but when these mechanisms fail, SV cannot be maintained during an elevated HR. These mechanisms include increased venous return, venous constriction, increased atrial and ventricular inotropy and enhanced rate of ventricular relaxation.

Normal values for a resting healthy individual would be approximately mL. Patients undergoing surgery or in critical illness situations may require higher than normal SV and it may be more appropriate to aim for optimal rather than normal SV.

Cardiac Output CO is the amount of blood the heart pumps from each ventricle per minute.
