From: Transpulmonary thermodilution-derived cardiac function index identifies cardiac dysfunction in acute heart failure and septic patients: an observational study

LVSWI = SVI × (MAP – PAOP) × 0.0136

CP = MAP × CO/451

ITTV = CO × MTt

PTV = CO × DSt

GEDV = ITTV - PTV = CO × (MTt - DSt)

ITBV = 1.25 × GEDV

CFI = (CO/GEDV) × 103

GEF = SV/(GEDV/4)

EVLW = ITTV - ITBV

PVPI = EVLW/PBV

  1. The detailed pathophysiological background is explained in Materials and methods. CFI: cardiac function index; CO: cardiac output; CP: cardiac power; DSt: exponential downslope time; EVLW: extravascular lung water; GEDV: global end-diastolic volume; GEF: global ejection fraction; ITBV: intrathoracic blood volume; ITTV: intrathoracic thermal volume; LVSWI: left ventricular stroke work index; MAP: mean arterial pressure; MTt: mean transit time; PAOP: pulmonary artery occlusion pressure; PBV: pulmonary blood volume; PTV: pulmonary thermal volume; PVPI: pulmonary vascular permeability index; SV: stroke volume; SVI: stroke volume indexed for body surface area.
