Calculate Cardiac Output
Cardiac output (CO) is a crucial vital sign that represents the amount of blood pumped by the heart in one minute. It’s calculated using the equation: CO = SV × HR, where SV is stroke volume and HR is heart rate.
How to Use This Calculator
- Enter the stroke volume in milliliters (ml).
- Enter the heart rate in beats per minute (bpm).
- Click “Calculate”.
Formula & Methodology
The cardiac output is calculated by multiplying the stroke volume by the heart rate. Stroke volume is the amount of blood pumped by the heart in one contraction, while heart rate is the number of heartbeats per minute.

| 20-30 | 5.0-7.0 |
Expert Tips
- Regular exercise can increase your stroke volume, improving your cardiac output.
- Stress and anxiety can decrease your stroke volume, negatively impacting your cardiac output.
