The cardiac output is simply the amount of blood pumped by the heart per minute. Necessarily, the cardiac output is the product of the heart rate, which is the number of beats per minute, and the stroke volume, which is amount pumped per beat.

CO = HR X SV

The cardiac output is usually expressed in liters/minute. For someone weighing about 70 kg (154 lbs), the cardiac output at rest is about 5 liters/minute. In this case, if the heart rate is 70 beats/min, the stroke volume would be a little more than 70 ml/beat.

But of course this changes dramatically as a person begins to exercise. For a typical, fit young person, the cardiac output might go up to about 20 liters/min at the peak of exercise. However, for a world-class athlete in an endurance sport, the maximum cardiac output might be around 35 liters/min.

The overall blood pressure as measured in the brachial artery is maintained by the cardiac output and the total peripheral resistance (TPR) to flow. The mean arterial pressure (MAP) is calculated by the formula:

where DBP and SBP are diastolic and systolic blood pressure, respectively. Mean arterial pressure is a useful concept because it can be used to calculate overall blood flow, and thus delivery of nutrients to the various organs. It is a good indicator of perfusion pressure (ΔP).
