What is the normal range for Cardiac Index (C.I.)?

The normal range for Cardiac Index (C.I.) is crucial for assessing cardiac function in relation to the body’s surface area. A Cardiac Index of 2.5 to 4 L/min/m² is considered normal, indicating that the heart is effectively pumping enough blood to meet the metabolic needs of the body while also taking into account the size of an individual.

Cardiac Index provides a more accurate representation of cardiac output relative to body size than cardiac output alone. It helps healthcare professionals determine if a patient is in a state of cardiovascular distress or is maintaining adequate blood circulation. The specified range allows for the evaluation of various clinical scenarios and helps in diagnosing conditions such as heart failure or cardiogenic shock, where deviations may be observed.

Understanding this normal range is essential for clinical assessments, as deviations below or above this range could indicate underlying health issues that need to be addressed.
