Pleth Variability Index (PVI®) is a breakthrough measurement that may help clinicians noninvasively and continuously assess fluid status of patients.

• Fluid administration is critical.
• To increase cardiac output and optimise patient status, enabling end organ preservation.
• Unnecessary fluid administration associated with increased morbidity and mortality.
• Fluid administration causes hemodilution, which reduces Hb concentration and increases likelihood of transfusion.
• Traditional static measurements not reliable to predict volume responsiveness: CVP, SBP, DBP, Pulse Pressure, Wedge Pressure, Cardiac output.
• New dynamic monitoring technologies are effective. Proven to improve outcomes but are invasive or complex – and costlys.
• Examples: Pulse pressure variation, stroke volume variation.
• Appropriate for higher-risk patients.
• There is a large opportunity to improve care in moderate to low risk population.
• Using low cost, noninvasive technology.
