Use Stroke Volume mL when you need to compute stroke volume as end-diastolic volume minus end-systolic volume. Enter End-diastolic volume and End-systolic volume using the definitions and units below so the result can be reproduced.

End-diastolic volume

A finite measured or assumed value greater than or equal to 5e-324, expressed in mL.

End-systolic volume

A finite measured or assumed value greater than or equal to 5e-324, expressed in mL.

The published tool contract uses this rule: Compute stroke volume as end-diastolic volume minus end-systolic volume.

Stroke volume

The calculated stroke volume in mL.

The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability.

Retain the original End-diastolic volume and End-systolic volume values and their units alongside the result. Plasma Volume mL is useful when you instead need to compute the plasma volume as blood volume times one minus the hematocrit fraction. Stroke Work Calculator provides another view by helping you compute left ventricular stroke work from stroke volume and pressure gradient.

• Plasma Volume mL

  Compute the plasma volume as blood volume times one minus the hematocrit fraction.

• Stroke Work Calculator

  Compute left ventricular stroke work from stroke volume and pressure gradient.

• Total Blood Volume Estimate

  Estimate total blood volume from body weight using the documented reference value of 70 millilitres per kilogram.
