Cardiac Stoke Volume

The Cardiac Stroke Volume calculator computes the volume blood pumped in one stroke based on the end diastolic and systolic volumes .

INSTRUCTIONS: Choose units and enter the following:

• (EDV) End Diastolic Volume
• (ESV) End Systolic Volume

Cardiac Stroke Volume (SV): The calculator returns the output volume in milliliters.  However this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The volume blood pumped by the heart in one stroke is the difference between the end diastolic volume and the end systolic volume, in particular by a left or right ventricle in the time interval of one stroke.  The formula for the stroke volume of a heart is

`SV = EDV-ESV`

where:

• SV = Stroke Volume which is the amount of blood pumped from one ventricle of the heart through one beat
• EDV = End-diastolic volume
• ESV = End-systolic volume

Systolic and Diastolic Volume

End Diastolic Volume (EDV)  is the volume of the ventricle before the heart contracts.  End Systolic Volume (ESV) is the ventricle volume after blood has been ejected from the heart.

 The typical end diastolic volume for a the average male is 120 milliliters of blood, and 50 milliliters of end-systolic blood.  

Heart and Cardiology Calculators

• Cardiac Stroke Volume: Computes the volume blood pumped in one stroke based on the end diastolic and systolic volumes.
• Cardiac Output: Computes the output of a heart based on the heart rate, end diastolic volume and the end systolic volume.
• Cardiac Output with Stroke Volume: Computes the volume rate of blood pumped by the heart in one minute based on the beats per minute and the stroke volume.
• Ejection Fraction: Computes the Ejection Fraction percentage based on the end-systolic and end-diastolic volumes.
• Heart Stroke Work: Computes the amount of work performed by the heart during a single heartbeat to pump blood based on the Mean Arterial Pressure (MAP) and Stroke Volume(SV).
• Mean Arterial Press: Compute the mean arterial pressure and pulse pressure based on the diastolic pressure and the systolic pressure.
• Cardiac Stroke Work: Computes work done by the ventricle to eject a volume of blood into the aorta based on the afterload pressure, stroke volume, blood stroke mass and blood flow velocity.
• Cardiac Flow (Q): Computes the flow factor of an artery based on the diameter and blood flow velocity.
• Body Surface Area (BSA): Wide range of calculators in one function to compute the body surface area base on one of many common methods (e.g., Mosteller, Takahira)
