Cardiac Output VTI Calculator

Calculate Cardiac Output





Formula

To calculate the Cardiac Output (CO):

\[ CO = \frac{VTI \times CSA \times HR}{1000} \]

What is Cardiac Output?

Cardiac Output is the volume of blood being pumped by the heart, in particular by the left or right ventricle, in one minute. It is a critical parameter in cardiac physiology and can be indicative of the heart’s efficiency and overall health. The measurement of Cardiac Output is essential in diagnosing and managing various cardiac conditions.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ CO = \frac{20 \times 3 \times 75}{1000} = 4.50 \text{ L/min} \]

The Cardiac Output is 4.50 L/min.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ CO = \frac{25 \times 2.5 \times 80}{1000} = 5.00 \text{ L/min} \]

The Cardiac Output is 5.00 L/min.
