The cardiac index calculator estimates cardiac function based on the cardiac output from the left ventricle in one minute, and the body surface area of the patient. We frequently measure the patient's cardiac index (CI) and use it in intensive care medicine and cardiac intensive care.
The Fick Formula calculates cardiac output, cardiac index, and stroke volume.
The equation for the cardiac index is mentioned below and is denoted in units of (L/min)/ (m 2): Cardiac index = cardiac output/body surface area (BSA) = (heart rate x stroke volume)/BSA. Cellular Level.
The cardiac index is adjusted for body surface area (BSA), typically calculated using the Mosteller formula. This adjustment allows for standardized comparison across individuals with different body sizes, improving the accuracy of CI measurements.
There are two ways to calculate CI: the first based on cardiac output and body surface area and the second based on stroke volume, heart rate and body surface area: CI (L/min/m 2) = CO/BSA. CI (L/min/m 2) = SV x HR / BSA. The normal range of cardiac index (at rest) is 2.6 – 4.2 L/min/m 2.
Cardiac Output Formula. Cardiac output (CO) is the volume of blood the heart pumps per minute. Cardiac output is calculated by multiplying the stroke volume by the heart rate. Stroke volume is determined by preload, contractility, and afterload.
A Cardiac Index Calculator is an online or offline tool that quickly calculates CI based on the Cardiac Output and Body Surface Area you input. These calculators often include built-in tools to estimate BSA from height and weight, making your life even easier.
The formula to calculate the Cardiac Index is: \ [ CI = \frac {CO} {BSA} \] where: \ (CI\) is the Cardiac Index in liters per minute per square meter (L/min/m²), \ (CO\) is the Cardiac Output in liters per minute (L/min), \ (BSA\) is the Body Surface Area in square meters (m²). Example Calculation.
Cardiac output is therefore calculated using the formula: Cardiac output = Oxygen consumption / Arteriovenous oxygen gradient; Normal values: Normal cardiac output is 4-8 L/min; Normal cardiac index is 2.5-4 L/min/m 2; Normal stroke volume is 60-100 ml/beat; Normal stroke volume index is 33-47 ml/beat/m 2
The formula for Cardiac Index is Cardiac Output / Body Surface Area. Cardiac Output is the amount of blood the heart pumps in one minute. Body Surface Area is calculated using a person's height and weight.
