systematic review of uncalibrated arterial pressure waveform analysis to determine cardiac output and stroke volume variation
BJA: British Journal of Anaesthesia, 2014Co-Authors: Cornelis Slagt, Ignacio Malagon, A B J GroeneveldAbstract:Summary The FloTrac/Vigileo™, introduced in 2005, uses arterial pressure waveform analysis to calculate cardiac output (CO) and stroke volume variation (SVV) without external calibration. The aim of this systematic review is to evaluate the performance of the system. Sixty-five full manuscripts on validation of CO measurements in humans, published in English, were retrieved; these included 2234 patients and 44 592 observations. Results have been analysed according to underlying patient conditions, that is, general critical illness and surgery as normodynamic conditions, cardiac and (post)cardiac surgery as hypodynamic conditions, and liver surgery and sepsis as hyperdynamic conditions, and subsequently Released Software versions. Eight studies compared SVV with other dynamic indices. CO, bias, precision, %error, correlation, and concordance differed among underlying conditions, subsequent Software versions, and their interactions, suggesting increasing accuracy and precision, particularly in hypo- and normodynamic conditions. The bias and the trending capacity remain dependent on (changes in) vascular tone with most recent Software. The SVV only moderately agreed with other dynamic indices, although it was helpful in predicting fluid responsiveness in 85% of studies addressing this. Since its introduction, the performance of uncalibrated FloTrac/Vigileo™ has improved particularly in hypo- and normodynamic conditions. A %error at or below 30% with most recent Software allows sufficiently accurate and precise CO measurements and trending for routine clinical use in normo- and hypodynamic conditions, in the absence of large changes in vascular tone. The SVV may usefully supplement these measurements.

cardiac output measured by uncalibrated arterial pressure waveform analysis by recently Released Software version 3 02 versus thermodilution in septic shock
Journal of Clinical Monitoring and Computing, 2013Co-Authors: Cornelis Slagt, Marcel A De Leeuw, Jan Beute, Emmy Rijnsburger, Martijn Hoeksema, Jan W R Mulder, Ignacio Malagon, A Johan B GroeneveldAbstract:To evaluate the 3.02 Software version of the FloTrac/Vigileo™ system for estimation of cardiac output by uncalibrated arterial pressure waveform analysis, in septic shock. Nineteen consecutive patients in septic shock were studied. FloTrac/Vigileo™ measurements (COfv) were compared with pulmonary artery catheter thermodilution-derived cardiac output (COtd). The mean cardiac output was 7.7 L min−1 and measurements correlated at r = 0.53 (P 10 % in both COtd and COfv (n = 46) were in the same direction. Eighty-five percent of the measurements were within the 30°–330° of the polar axis. COfv with the latest Software still underestimates COtd at low SVR in septic shock. The tracking capacities of the 3.02 Software are moderate-good when clinically relevant changes are considered.
