Calculate cardiac output from heart rate and stroke volume, and cardiac index from Mosteller BSA.
| CO | – |
| CI (L/min/m²) | – |
Use this calculator for CO = heart rate × stroke volume / 1000, in litres per minute, and CI = CO / Mosteller BSA. It is not a Fick or thermodilution measurement.
Stroke volume can be entered in millilitres (ml) or fluid ounces (fl oz). Weight can be entered in kilograms (kg) or pounds (lb). Height can be entered in centimetres (cm) or inches (in). Cardiac output follows the volume unit (L/min or gal/min).
Heart rate: Beats per minute.
Stroke volume: Volume ejected per beat, in ml or fl oz.
Weight: Body weight for BSA, in kg or lb.
Height: Standing height for BSA, in cm or in.
CO: Cardiac output.
CI: Cardiac index in L/min/m² (not unit-converted).
