What is cardiac output?

ANSWER

It’s how much blood your heart pumps in 1 minute. Your doctor uses the measurement to see if you might have heart problems or to check how well a treatment works.

Your blood carries oxygen and nutrients to your cells, and it takes away wastes like carbon dioxide. If your heart pumps too little or too much blood through your body, it could be a sign of heart failure or other medical problems.
