The present study shows that transpulmonary thermodilution with indicator injection via femoral instead of jugular CVC leads to an underestimation of the pulmonary permeability index (PVPI), since the correction applied by the manufacturer for the global end-diastolic volume (GEDV) is inconsistent with the calculation of the PVPI applied. As part of the study, two comparable correction approaches were developed, which, when applied to femoral indicator injections, result in corrected PVPI values for femoral indicator injection.
