What is the expected range for cardiac output in a healthy adult?

The expected range for cardiac output in a healthy adult is typically between 4 to 6 liters per minute. Cardiac output is a critical measurement that reflects the effectiveness of the heart's pumping ability and is calculated as the product of stroke volume and heart rate.

In a healthy individual, a cardiac output within this range signifies that the cardiovascular system is functioning optimally, supplying adequate blood flow to meet the metabolic demands of the body. Values below this range may indicate inadequate blood flow and potential cardiovascular issues, while values exceeding this range could suggest an increased demand on the heart, possibly due to exercise or other stressors.

Understanding this normal range is essential for healthcare professionals to assess cardiac function and determine the presence of any deviations that may require intervention.
