What is a high cardiac index?

A high cardiac output has been described as being >8 l/min or a cardiac index >3.9 l/min/m2. 16. A high cardiac output state and associated clinical heart failure is associated with several disease states (Figure 1).Click to see full answer. Also asked, what does a high cardiac index mean?In terms of cardiac output, a high cardiac output state is defined as a resting cardiac output greater than 8 L/min or a cardiac index of greater than 4.0/min/m2 [1], and heart failure occurs when that cardiac output is insufficient to supply the demand.Similarly, what increases cardiac index? Milrinone increases cardiac index with reductions in arterial pressure, left ventricular end-diastolic pressure, and pulmonary vascular resistance. Heart rate can increase, although this is not a consistent response and bradycardia can also occur. Secondly, what is the normal range for cardiac index? Cardiac Index (CI) The cardiac index is an assessment of the cardiac output value based on the patient’s size. To find the cardiac index, divide the cardiac output by the person’s body surface area (BSA). The normal range for CI is 2.5 to 4 L/min/m2.What does Decreased cardiac index mean?A low cardiac index of less than 2.5 L/min/m2 usually indicates a marked disturbance in cardiovascular performance and is almost always clinically apparent. Although the resting cardiac output or index is an insensitive measure of cardiovascular performance, it is clinically valuable in critically ill patients.
