It is calculated as cardiac output divided by body surface area (BSA). It is used in cardiovascular physiology, critical care, and perioperative medicine to describe global circulatory performance. It is most commonly discussed in shock, heart failure, and invasive or noninvasive hemodynamic monitoring."}
