Open Access Abstract Introduction This study was designed to test the hypothesis of equivalence in cardiac output CO and stroke volume SV monitoring capabilities of two devices non invasive transthoracic bioreactance NICOM and a pulse contour analysis PICCO PC coupled to transpulmonary thermodilution PICCO TD . Methods We included consecutive patients of a single ICU following cardiac surgery. Continuous minute-by-minute hemodynamic variables obtained from NICOM and PICCO PC were recorded and compared in 20 patients at baseline during a lung recruitment maneuver 20 cmH2O of PEEP and following withdrawal of PEEP. PICCO TD measurements were also determined. We evaluated the accuracy of these two technologies at baseline using PICCO TD as reference and we estimated the precision by the fluctuation around the mean value 2SD mean . Then we assessed time response amplitude response and reliability for detecting expected decreases when PEEP was applied. Type I and type II errors were analyzed. Results CO values PICCO TD ranged from 1.6 to 8.0 L.min-1.
