Cardiac Output Calculator
Calculate cardiac output from heart rate and stroke volume
About this calculator
The Cardiac Output Calculator determines how much blood your heart pumps per minute by multiplying heart rate (beats per minute) by stroke volume (blood pumped per beat). This measurement is crucial for assessing cardiovascular health, diagnosing heart conditions, and monitoring patient recovery. Healthcare professionals use cardiac output values to evaluate heart function, adjust medications, and make treatment decisions for patients with heart disease or during medical procedures.
How to use
Enter your heart rate in beats per minute and stroke volume in milliliters per beat into the calculator. The tool will automatically multiply these values to calculate your cardiac output in liters per minute. Normal cardiac output ranges from 4-8 L/min for healthy adults at rest.
Frequently asked questions
What is normal cardiac output?
Normal cardiac output for healthy adults at rest is typically 4-8 liters per minute, with an average of about 5-6 L/min.
How is stroke volume measured?
Stroke volume is measured using echocardiography, cardiac catheterization, or other imaging techniques that assess blood ejected per heartbeat.
What affects cardiac output?
Cardiac output is influenced by heart rate, stroke volume, physical activity, age, body size, medications, and cardiovascular health conditions.
