Cardiac Output Calculator

Cardiac Output Calculator calculator can be used to calculate the amount of blood the heart pumps per minute, which is an important indicator of cardiac function.

Input Parameters

Calculation Results

Calculation Formula

Cardiac Output (CO) = Heart Rate (HR) × Stroke Volume (SV)

Where:
Cardiac Output (CO): The volume of blood pumped by the heart per minute
Heart Rate (HR): The number of heartbeats per minute
Stroke Volume (SV): The volume of blood ejected by the left ventricle with each heartbeat

Cardiac Output Calculator Calculator Usage Guide

Learn how to use the Cardiac Output Calculator calculator and its working principles

How to Use the Calculator

  1. Enter your heart rate in beats per minute (bpm)
  2. Enter your stroke volume in milliliters per beat (mL/beat)
  3. Click the "Calculate" button to compute your cardiac output
  4. The result will be displayed in liters per minute (L/min)

Understanding Cardiac Output

Cardiac output (CO) is the volume of blood being pumped by the heart per minute. It's an important measure of cardiac function and can help assess the heart's ability to supply oxygen to the body's tissues.

The formula used is:

CO = HR × SV

Where HR is Heart Rate (beats per minute) and SV is Stroke Volume (mL per beat).

Normal Values

  • Resting adults: 4.5 - 6.5 L/min
  • During exercise: Can increase to 15 - 25 L/min or more depending on fitness level

When to Use This Calculator

This calculator is useful for:

  • Assessing cardiac function in clinical settings
  • Monitoring patients with heart conditions
  • Estimating oxygen delivery to tissues
  • Comparing changes in cardiac output during exercise or stress testing
