What measurement represents the combined volume of blood the heart pumps in a given time frame?

The measurement that represents the combined volume of blood the heart pumps in a given time frame is cardiac output. Cardiac output is calculated by multiplying stroke volume, which is the amount of blood pumped by the heart with each beat, by heart rate, which is the number of beats per minute. This is critical in evaluating heart function and understanding how well blood is being circulated throughout the body. Adequate cardiac output is vital for supplying organs and tissues with the necessary oxygen and nutrients they require for proper functioning.
