        Purpose: It has been reported that the Pulse Contour Cardiac Output (PiCCO) is very useful mainly in the field of intensive care and treatment to grasp the pathophysiologicalconditions of pulmonary edema because of its capability of obtainingdata such as Pulmonary Vascular Permeability Index (PVPI) and Extra VascularLung Water (EVLW). Furthermore, a high degree of usability of various markers has been reported for better understanding of the pathological conditions in cases with septicemia. Materials and Methods: The correlation between the cardiorespiratory status based upon the PiCCO monitor (EVLW and PVPI) and inflammatorymarkers including C reactive protein, procalcitonin (PC), and EndotoxinActivity Assay (EAA) were evaluated in 11 severe cases that required treatmentwith a respirator in an intensive care unit. Results: The EAA values were significantly higher in patients with abnormal EVLW at 0.46±0.20 compared to the normal EVLW group at 0.21±0.19 (p=0.0064). In a similar fashion, patients with abnormal PVPI values tended to have higher PC levels at 18.9±21.8 comparedto normal PVPI cases at 2.4±2.2 (p=0.0676). On the other hand, PVPI was significantly higher in the abnormal EAA group at 3.55±0.48 in comparison with the normal EAA group at 1.99±0.68 (p=0.0029). The abnormal EAA group tended to have higher PVPI values than the normal EAA group. Conclusion: The EAA is a measurement method designed to estimate the activity of endotoxins in the whole blood. Our results suggest that the EAA value, which had the greatest correlationwith lung disorders diagnosed by the PiCCO monitoring, reflects inflammatoryreactions predominantly in the lungs.
