Abstract
PVI (Plethysmography variability index) and PPV (pulse pressure variation) using cardiac index as a reference parameter. PVI showed accurate fluid responsiveness in comparison with PPV in responders with mean ranging from (-6.66 ± 0.90) and (-5.89 ± 1.93) respectively ,with a P-value<0.01
Conclusion: This study revealed that after giving a fluid challenge of 500 ml of saline over 30 minutes, a rise in PVI and PPV was demonstrated using cardiac index as a reference for reliability for comparing the effectiveness and accuracy between PVI and PPV.PVI and PPV can be used in assessment of fluid responsiveness of the intubated ventilated sedated patients with sinus rhythm in ICU, and both methods can be performed at the bedside, but PVI has advantage of being continuous, operator independent, and more reliable than PPV.
