Uncalibrated pulse contour-derived stroke volume variation predicts fluid responsiveness in mechanically ventilated patients undergoing liver transplantation.
BACKGROUND Stroke volume variation (SVV) is able to predict adequately the individual response to fluid loading. Our objective was to assess whether the SVV measured by a new algorithm (Vigileo; Flotrac) can predict fluid responsiveness. METHODS Forty mechanically ventilated patients undergoing liver transplantation, who needed volume expansion (VE), were included. VE was done with albumin (4...
متن کاملEvaluation of stroke volume variation obtained by arterial pulse contour analysis to predict fluid responsiveness intraoperatively.
BACKGROUND Fluid management guided by oesophageal Doppler monitor has been reported to improve perioperative outcome. Stroke volume variation (SVV) is considered a reliable clinical predictor of fluid responsiveness. Consequently, the aim of the present trial was to evaluate the accuracy of SVV determined by arterial pulse contour (APCO) analysis, using the FloTrac/Vigileo system, to predict fl...

Which means that SVV (%) ≈ pulse pressure variation (PPV; %) for FloTracTM. With the present mathematical equation, it can be demonstrated that the SVV calculated by FloTracTM (SVVFT) is not infl uenced by Khi, which means that SVVFT calculation does not include eff ective arterial elastance (Ea). Th e originality of Garcia and colleagues’ fi nding is that they realized that when measuring PPV ...
متن کاملEvaluation of the pulse-contour method of determining stroke volume in man.
one patients with ischemic heart disease and 21 patients with mitral valve disease were subjected to a variety of hemodynamic interventions. These included exercise, isoproterenol infusion, and practolol, morphine or pentazocine administration. The pulse-contour estimations, using three different formulae derived by Warner, Kouchoukos, and Herd, were compared with indicator-dilution outputs. Th...
