What is a normal cardiac output?

ANSWER

It’s different for different people, depending on their size. Usually, an adult heart pumps about 3-4 liters of blood per minute at rest. But when you run or exercise, your heart may pump 3-4 times that much to make sure your body gets enough oxygen and fuel.
