Cardiac Index Calculator

Formula

The formula to calculate the Cardiac Index is:

\[ CI = \frac{CO}{BSA} \]

Where:

CI is the Cardiac Index (L/min/m²)
CO is the cardiac output (L/min)
BSA is the body surface area (m²)

What is Cardiac Index?

The Cardiac Index (CI) is a measure of the cardiac output of a patient divided by their body surface area. It provides a more accurate assessment of the heart's efficiency relative to the size of the individual, helping in the diagnosis and management of various cardiac conditions.

Example Calculation

Let's assume the following values:

Cardiac Output (CO): 5 L/min
Body Surface Area (BSA): 1.8 m²

Step 1: Calculate the Cardiac Index using the formula:

\[ CI = \frac{5}{1.8} \approx 2.78 \]

The Cardiac Index (CI) is approximately 2.78 L/min/m².
