A Cardiac Index (CI) calculator is a tool that calculates the cardiac index of a person based on their cardiac output and body surface area. The cardiac index is a measure of the cardiac output adjusted for body size and is used to assess cardiac function and output in a clinical setting.
The formula for calculating the cardiac index is:
CI = Cardiac Output / Body Surface Area
- Cardiac Output is the amount of blood pumped by the heart per minute and is usually measured in liters per minute (L/min)
- Body Surface Area is the surface area of a person’s body and is usually measured in square meters (m^2)
To use a CI calculator, you need to input the values of cardiac output and body surface area, and the calculator will calculate the corresponding CI for you. The resulting CI value can then be used to assess cardiac function and output in a clinical setting, such as in the diagnosis and management of heart failure, cardiogenic shock, or other cardiac conditions.
It is important to note that the normal range of CI may vary depending on age, gender, and other factors, and that the interpretation of CI values should be done in the context of the individual patient and their clinical condition.
