Cardiac Output Calculator
❤️ The human body. Use the Cardiac output formula to find cardiac output, heart rate, stroke volume: pick the value you want, type the others, and the answer updates as you go.
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Cardiac output | L/min |
| Heart rate | bpm |
| Stroke volume | ml |
Worked example
Find the cardiac output when Heart rate = 70 bpm, Stroke volume = 70 ml.
Using cardiac output = heart rate × stroke volume: Cardiac output = 4.9 L/min.
Frequently asked questions
What is the formula for Cardiac output?
cardiac output = heart rate × stroke volume.
What do the letters stand for, and what units are used?
Cardiac output in L/min, Heart rate in bpm, Stroke volume in ml.
How do you calculate cardiac output?
Put the values into cardiac output = heart rate × stroke volume. For example, with Heart rate = 70 bpm, Stroke volume = 70 ml, cardiac output = 4.9 L/min.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (cardiac output, heart rate, stroke volume) and fill in the others: it rearranges the formula for you.
