What is the normal range for the cardiac index?

The normal range for cardiac index is crucial for assessing cardiac function relative to body surface area. The correct range is typically considered to be 2.5-4 L/min/m². This index allows healthcare providers to evaluate how well the heart is pumping blood in relation to the size of the individual, providing a more accurate picture of cardiac performance than cardiac output alone.

A cardiac index lower than 2.5 L/min/m² may indicate poor heart function or heart failure, while a cardiac index higher than 4 L/min/m² could suggest hyperdynamic circulation or conditions such as sepsis. Understanding this range is essential for monitoring patients in critical care settings as it influences management decisions and guides treatment strategies. Evaluating the cardiac index effectively helps clinicians make informed decisions about hemodynamic support and overall cardiac care.
