Question

cardiac output is determined by ?​

Answer 1

Cardiac output is the product of the heart rate (HR), or the number of heart beats per minute (bpm), and the stroke volume (SV), which is the volume of blood pumped from the ventricle per beat; thus, CO = HR × SV. Values for cardiac output are usually denoted as L/min.

Answer 2

Cardiac output is the product of two variables, stroke volume and heart beat. Heartbeat is simply a count of the number of times a heart beats per minute. Stroke volume is the amount of blood circulated by the heart with each beat. The formula for this is expressed as CO = SV x HR
