Stroke Volume Calculator

How to use the Stroke Volume Calculator

1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

stroke_volume = cardiac_output/heart_rate

stroke_volume_index = one_way(stroke_volume / body_surface_area)

cardiac_index = one_way(cardiac_output/body_surface_area)

body_surface_area = one_way(0.007184 × pow(weight, 0.425) × pow(height×100, 0.725))

Frequently asked questions

What is a stroke volume calculator?

A stroke volume calculator is a tool designed to compute the amount of blood ejected by the heart’s left ventricle during each heartbeat. It’s an essential metric used in assessing cardiovascular health and efficiency.

How is stroke volume calculated?

Stroke volume is calculated using the formula: Stroke Volume (SV) = End Diastolic Volume (EDV) – End Systolic Volume (ESV). By measuring these two values, you can determine the volume of blood pumped out with each contraction.

Why is stroke volume important?

Stroke volume plays a critical role in evaluating cardiac output and overall heart function. It helps doctors understand heart efficiency, the impact of various conditions, and the effectiveness of treatments for heart diseases.

What factors affect stroke volume?

Several factors influence stroke volume, including:

• Heart rate: A higher heart rate can lead to decreased stroke volume.
• Contractility: The strength of the heart’s contraction impacts the amount of blood ejected.
• Preload: Increased filling of the heart before contraction can raise stroke volume.
• Afterload: The resistance the heart must overcome to eject blood can affect stroke volume.

Who should use a stroke volume calculator?

A stroke volume calculator is beneficial for healthcare professionals assessing patients’ heart health, athletes monitoring performance, and anyone interested in understanding their cardiovascular fitness.

Where can I find a reliable stroke volume calculator?

Many reputable health websites and medical apps offer stroke volume calculators. Ensure you are using a tool from a credible source, such as Healthline or Mayo Clinic, for accurate results.
