Cardiac Output with Stroke Volume

The Cardiac Output with Stroke Volume calculator computes the volume rate of blood pumped by the heart in one minute based on the beats per minute and the stroke volume.

INSTRUCTIONS: Choose units and enter the following:

• (HR) Heart Rate
• (SV) Stoke Volume

Cardiac Output (CO): The calculator returns the output volume in milliliters per minute.  However this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

Cardiac Output is the volume rate of blood being pumped by the heart, in particular by a left or right ventricle in the time interval of one minute.  The formula for cardiac output is

`CO = ("HR")*("SV")`

where:

• CO = Cardiac Output
• HR = Heart Rate in beats (strokes) per minute (BPM)
• SV = Stroke Volume which is the amount of blood pumped from one ventricle of the heart through one beat

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)
