Introduction. Nexfin (Bmeye, Amsterdam, Netherlands) is a noninvasive cardiac output (CO) monitor based on finger arterial pulse contour analysis. The aim of this study was to validate Nexfin CO (NexCO) against thermodilution (TDCO) and pulse contour CO (CCO) by PiCCO (Pulsion Medical Systems, Munich, Germany).Patients and Methods. In a mix of critically ill patients (n=45), NexCO and CCO were measured continuously and recorded at 2-hour intervals during the 8-hour study period. TDCO was measured at 0–4–8 hrs.Results. NexCO showed a moderate to good (significant) correlation with TDCO (R20.68,P<0.001) and CCO (R20.71,P<0.001). Bland and Altman analysis comparing NexCO with TDCO revealed a bias (± limits of agreement, LA) of 0.4 ± 2.32 L/min (with 36% error) while analysis comparing NexCO with CCO showed a bias (±LA) of 0.2 ± 2.32 L/min (37% error). NexCO is able to follow changes in TDCO and CCO during the same time interval (level of concordance 89.3% and 81%). Finally, polar plot analysis showed that trending capabilities were acceptable when changes in NexCO (ΔNexCO) were compared toΔTDCO andΔCCO (resp., 89% and 88.9% of changes were within the level of 10% limits of agreement).Conclusion. we found a moderate to good correlation between CO measurements obtained with Nexfin and PiCCO.

Traditional, static measures of resuscitation, such as vital signs, central venous pressure, and pulmonary arterial pressure, provide momentary glimpses evolving hemodynamic states. In patients with shock, these measures of resuscitation are poor indicators of response to therapy. As a result, dynamic assessments of cardiovascular status are now used in critically ill patients to facilitate resuscitation. Some of these approaches focus on fluid responsiveness. These assessments allow care to be tailored to each patient’s response to interventions. An evolving aspect of hemodynamic monitoring is evaluation of the adequacy of tissue perfusion and oxygen delivery. In this review, we consider the use of arterial, central venous, and pulmonary arterial blood pressure monitoring; echocardiography; transesophageal Doppler technology; pulse contour analysis; bioimpedance and bioreactance; and partial rebreathing monitoring modalities to assess hemodynamic status in critically ill patients.  This review contains 22 figures, 5 tables, and 38 references. Key words: echocardiography, esophageal Doppler technology, invasive and noninvasive hemodynamic monitoring, pulse contour analysis, shock
