<prompt> Cardiac output in Lmin divided by hea rate equals:Cardiac efficiencyMean stroke volumeCardiac indexMean aerial pressure  <response>: Answer is B Mean Stroke Volume Mean stroke volume is the amount of blood pumped out of each ventricle per beat. It is calculated as the cardiac output in Lmin divided by the hea rate. Mean Stroke Volume Cardiac Output Hear Rate Parameter Definition Value Cardiac output The output of the hea per unit time 5Lmindeg Stroke volume The amount of blood pumped out of each ventricle per beat.
