5 L per minute: The average cardiac output is somewhere around 5 l per minute. Cardiac output varies with the size of the patient (larger patients have larger cardiac output). Cardiac output is increased in conditions such as fever, anemia, or pregnancy.

Cardiology 16 years experience
By Size: 2.6-4.2 l/min of blood per m^2 of body surface area. Most "normal" sized people are ~2m^2 bsa, but few people in this country count as normal :) figure something over 4 l/min to be safe. Cardiac shock occurs below ~2l/min.

What is the average number for cardiac output?

4 to 5 liters/min: Approximately 4-5 l per minute. The cardiac output is proportional to the size of the patient. You can "normalize" the cardiac output by dividing the cardiac output by the body surface area resulting in a "cardiac index". The cardiac index is typically 2-3 l per minute per meter squared.

Heart pump volume: The cardiac output is the volume of blood per minute pumped by the heart. Cardiac output is equal to heart rate multiplied by stroke volume (the volume of blood ejected with each heartbeat).
