What is the minimal cardiac index used in pediatric patients?

In pediatric patients, the minimal cardiac index is typically considered to be 2.5 liters per minute per square meter (L/min/m²). This value reflects the amount of blood the heart pumps in relation to the body surface area and is essential for ensuring that all organ systems receive adequate perfusion.

Maintaining a cardiac index at or above this threshold is critical because it indicates sufficient cardiac output to meet the metabolic demands of growing children. In pediatric patients, lower cardiac index values can lead to inadequate tissue perfusion and may result in organ dysfunction. Therefore, the importance of monitoring this parameter in pediatrics cannot be overstated, particularly in critical care and during procedures involving cardiopulmonary bypass.

Understanding the significance of the cardiac index helps healthcare professionals make informed decisions regarding fluid management, inotropic support, and other interventions necessary to optimize cardiovascular performance in this vulnerable population.
