Stroke Volume Calculator

Calculates stroke volume from cardiac output and heart rate.

Inputs

Color mode links each input to the matching equation term and solving arithmetic.

Equation and Work

mL/beat
SV status
—
60–130 reference
Normal/reference: Stroke volume is commonly about 60–130 mL/beat.

Clinical Significance

Stroke volume estimates milliliters ejected per heartbeat from cardiac output and heart rate. The constant 1000 converts cardiac output from liters per minute to milliliters per minute.

Used to evaluate beat-to-beat pump output. Cardiac output is converted from L/min to mL/min before dividing by heart rate.

Calculator output should be interpreted with the patient’s condition, measurement quality, and local clinical policy.
