APPARATUS AND COMPUTER PROGRAM FOR ASSESSING A PATIENT'S EXTRAVASCULAR LUNG WATER VOLUME

摘要

An apparatus for assessing extravascular lung water volume (EVLW) of a patient after lung resection is adapted to provide a transpulmonary thermodilution curve, is capable to derive the patient's intrathoracic thermal volume (ITTV) and approximated intrathoracic blood volume (ITBVapprox) from the transpulmonary thermodilution curve, and is capable to determine the extravascular lung water volume (EVLW) by correcting by the degree of lung resection (c), wherein making use of the equation EVLW = f(ITTV, ITBVapprox, c) , or EVLW = f(ITTV, GEDV, c). Further, a computer program for assessing extravascular lung water volume (EVLW) of a patient after lung resection, has instructions adapted to carry out the steps of generating a transpulmonary thermodilution curve on basis of provided measurement data collected at the patient, deriving the patient's intrathoracic thermal volume (ITTV) and approximated intrathoracic blood volume (ITBVapprox) from the transpulmonary thermodilution curve, and determining the extravascular lung water volume (EVLW) by correcting by the degree of lung resection (c), wherein making use of the equation EVLW = f (ITTV, ITBVapprox, c) or EVLW = f (ITTV, GEDV, c), when run on a computer.
