Transpulmonary thermodilution using femoral indicator injection: a prospective trial in patients with a femoral and a jugular central venous catheter

Table 3 Predictive capabilities of uncorrected and corrected femoral global end-diastolic volume index

	Uncorrected GEDVIfem	GEDVIfem - mean bias (GEDVIfem - GEDVIjug)	GEDVIfem corrected by the correction formula
Diagnostic accuracy	67%	90%	88%
Sensitivity elevated GEDVIjug	100	100	100
Specificity elevated GEDVIjug	61	91	96
PPV elevated GEDVIjug	74	93	96
NPV elevated GEDVIjug	100	100	100
Sensitivity decreased GEDVIjug	31	100	81
Specificity decreased GEDVIjug	100	91	94
PPV decreased GEDVIjug	100	84	87
NPV decreased GEDVIjug	74	100	91

Diagnostic accuracy, sensitivity, specificity, positive predictive value, negative predictive value for the prediction of jugular global end-diastolic volume based on uncorrected femoral global end-diastolic volume index, femoral global end-diastolic volume index corrected by subtraction of the mean bias and femoral global end-diastolic volume index corrected by the correction formula.
GEDVIfem, femoral global end-diastolic volume index; GEDVIjug, jugular global end-diastolic volume index; PPV, positive predictive value; NPV, negative predictive value. Elevated GEDVI means GEDVI >800 mL/m² and decreased GEDVI means GEDVI <680 mL/m²
