Product catalog summary
Pleth Variability Index (PVI®) Overview
Pleth Variability Index (PVI®) is a noninvasive and continuous measurement tool designed to help clinicians assess the fluid status of patients. It is particularly useful in predicting fluid responsiveness in mechanically ventilated patients under general anesthesia during surgery and in the ICU.

Clinical Benefits
  • PVI aids in optimizing fluid administration, which is crucial for patient status improvement.
  • Traditional methods often fail to predict fluid responsiveness, whereas PVI provides a noninvasive alternative.
  • Studies have shown PVI's effectiveness in improving fluid management and reducing lactate levels compared to standard care.

Technology Platform
  • PVI is calculated based on the dynamic change in Perfusion Index (PI) during the respiratory cycle.
  • A PVI greater than 14% before volume expansion indicates a high likelihood of fluid responsiveness (81% sensitivity), while a PVI less than 14% indicates non-responsiveness (100% specificity).
  • PVI demonstrates high accuracy in distinguishing fluid responders from non-responders, with an area under the curve of 0.93, comparable to invasive methods.

Masimo rainbow SET® Platform
  • The platform offers noninvasive monitoring of multiple blood constituents and physiological parameters, reducing the need for invasive procedures.
  • It includes measurements such as Acoustic Respiration Rate (RRa™), Carboxyhemoglobin (SpCO®), Methemoglobin (SpMet®), and others.

Conclusion
PVI provides a unique opportunity for clinicians to manage patient fluid volume effectively, optimizing cardiac performance and organ perfusion.

CLINICAL BENEFITS Pleth Variability Index (PVI) Arterial Pulse Pressure (APP) Pulmonary Capillary Wedge Pressure (PCWP) Central Venous Pressure (CVP) Adapted from Cannesson M. et a I. Br J Anesth 2008;101(2):200-206. PVI showed a similar accuracy (0.93 area under the curve) vs. pulse pressure variation from an invasive arterial catheter (0.94) and superior accuracy vs. cardiac index (0.56), central venous pressure (0.42), and pulmonary capillary wedge pressure (0.40). PVI has been shown to help clinicians to predict fluid ventilated patients under general anesthesia, defined as a significant...
