Cardiac Index Calculator

HEALTH & MEDICINE CALCULATOR Cardiac Index Calculator A precise tool.
📖
What is the Cardiac Index Calculator & How does it work?
The Cardiac Index (CI) is a measure of the heart’s ability to pump blood relative to body surface area. It is calculated by dividing the cardiac output (CO) by the body surface area (BSA). The formula for CI is:
CI = frac{CO}{BSA}
CI = Cardiac Index, CO = Cardiac Output, BSA = Body Surface Area
Cardiac output is the volume of blood pumped by the heart per minute and can be estimated using the Fick principle or other methods. Body surface area is typically calculated using the Mosteller formula: BSA (m²) = sqrt{frac{weight(kg) times height(cm)}{3600}}.A normal cardiac index for adults ranges from 2.5 to 4.0 L/min/m². Values outside this range may indicate heart failure, shock, or other cardiovascular conditions.

Frequently Asked Questions
What is cardiac index?
Cardiac index is a measure of the heart’s ability to pump blood relative to body surface area, calculated by dividing cardiac output by body surface area.
How do I calculate cardiac output?
Cardiac output can be estimated using the Fick principle or other methods, such as measuring stroke volume and heart rate.
What is the Mosteller formula for body surface area?
The Mosteller formula calculates BSA by taking the square root of (weight in kg x height in cm) divided by 3600.
Why is cardiac index important?
Cardiac index helps assess heart function and efficiency, especially in critical care settings where maintaining adequate blood flow is crucial.
What are the normal values for cardiac index?
Normal adult cardiac index ranges from 2.5 to 4.0 liters per minute per square meter (L/min/m²), but can vary based on age, sex, and overall health.
Can I use this calculator for children?
This calculator is primarily designed for adults. For children, different formulas and considerations may be necessary due to differences in physiology.
How often should I calculate my cardiac index?
Cardiac index should be calculated as needed, particularly in medical settings where monitoring heart function is critical. Regular checks can help assess changes in health status.
