Explanation:
Detailed explanation-1: -The cardiac output (CO) is the amount of blood ejected from the left ventricle, and normally it is equal to the venous return. The calculation is CO = stroke volume (SV) x heart rate (HR). CO also equals the rate of oxygen consumption divided by the difference in arterial and venous oxygen content.
Detailed explanation-2: -As we all know, Cardiac output is the total volume of blood that heart pumps every minute. The formula used to calculate cardiac output is given as CO = HR × SV.
