Cardiac Index Calculator calculator can be used to calculate the cardiac index (CI), which is a measure of the heart's effectiveness in pumping blood. It is calculated as the cardiac output (CO) divided by the body surface area (BSA).
Learn how to use the Cardiac Index Calculator calculator and its working principles
The Cardiac Index (CI) is a measure of the heart's effectiveness in pumping blood. It is calculated by dividing the Cardiac Output (CO) by the Body Surface Area (BSA). The Cardiac Output is the volume of blood being pumped by the heart per minute, and the Body Surface Area is the body surface area of a person in square meters.
If a patient has a Cardiac Output of 6.5 L/min and a Body Surface Area of 1.75 m², the Cardiac Index would be calculated as follows:
CI = 6.5 L/min / 1.75 m² = 3.71 L/min/m²
A normal Cardiac Index range is typically between 2.6 and 4.0 L/min/m² for adults. Values outside this range may indicate cardiovascular problems and should be interpreted by a healthcare professional.
