WebJan 9, 2024 · So you know the answer to the question: "What is cardiac index?", but what does the cardiac index formula look like? We present the equation below: CI = CO / BSA. where: CI - cardiac index, expressed in L/min/m²;. CO - cardiac output, expressed in L/min; and. BSA - body surface area, expressed in m².. The normal cardiac index range is … WebThe formula is: MPI = (IVCT + IVRT) / ET. IVCT = Isovolumetric contraction time IVRT = Isovolumetric relaxation time ET= Ejection time. When systolic dysfunction is present in patients IVCT will increase and ET decrease. Applied in the formular this will lead to an increased MPI. Normal range is considered at 0,39+/-0,05.
