Detailed explanation-1: -The formula used to calculate cardiac output is given as CO = HR × SV. SV-Stroke volume-the amount of blood circulated by the heart with each beat.
Detailed explanation-2: -We can use this simple calculation to figure out cardiac output: Cardiac Output = Stroke Volume * Heart Rate, which is written CO = SV * HR. Remember, there are two variables that are used to determine the cardiac output. Those are the stroke volume and heart rate.
Detailed explanation-3: -Heart rate is the number of beats per minute when a person is at rest. The stroke volume is a measure of how much blood the heart is taking in and pushing out within each beat. The formula for determining cardiac output is CO = HR x SV.
Detailed explanation-4: -Cardiac output is therefore calculated using the formula: Cardiac output = Oxygen consumption / Arteriovenous oxygen gradient.
Detailed explanation-5: -1.15. Cardiac output is a measurement of the amount of blood pumped by each ventricle in 1 min. To calculate cardiac output, SV is multiplied by the HR, the number of cardiac cycles per minute. It can be represented mathematically by the following equation: CO = HR × SV (see Fig. 1.22).
