ABSTRACT:
From the global end-diastolic volume GEDV and the global ejection fraction GEF the patient monitor (4) determines a corrected global end-diastolic volume cGEDV according toin-line-formulae description="In-line Formulae" end="lead"?cGEDV=GEDV/ƒ(GEF)in-line-formulae description="In-line Formulae" end="tail"?which is used as a novel parameter for volume responsiveness of the patient (3). In the above formula, f(GEF) is a correction function depending on global ejection fraction GEF. Further, from the right ventricular end-diastolic volume RVEDV and the right ventricular ejection fraction RVEF the patient monitor (4) determines a corrected right ventricular end-diastolic volume cRVEDV according toin-line-formulae description="In-line Formulae" end="lead"?cRVEDV=RVEDV1f(RVEF)in-line-formulae description="In-line Formulae" end="tail"?which is used as another novel parameter for volume responsiveness of the patient (3). In the above formula, f(RVEF) is a correction function depending on right ventricular ejection fraction RVEF.
