Calculating Cardiac Output with Stroke Volume and Heart Rate

Cardiac output is the total volume of blood pumped by the heart per minute. It is a critical indicator of cardiovascular health and function. This calculator uses the most fundamental formula for determining cardiac output.

The Formula:

The relationship is simple: Cardiac Output (CO) = Stroke Volume (SV) × Heart Rate (HR).

  • Stroke Volume (SV): The amount of blood pumped out of the left ventricle of the heart during each contraction, typically measured in milliliters (mL).
  • Heart Rate (HR): The number of times the heart beats per minute (bpm).

    • Enter the stroke volume and heart rate into the calculator to get the cardiac output in liters per minute (L/min). This tool is ideal for students, fitness professionals, and anyone interested in understanding basic cardiovascular physiology.
