Continuous Noninvasive Monitoring with Plethysmograph Variability Index

Masimo’s Plethysmograph Variability Index (PVI), a noninvasive measurement that quantifies changes in the plethysmographic waveform derived from pulse oximetry, can provide clinicians with a noninvasive way to monitor functional hemodynamics in their patients.
Clinicians who have evaluated PVI believe this technology will prove to be a valuable clinical tool with significant advantages over currently available indicators of changes in functional hemodynamics that are invasive, operator dependent, often inaccurate and expensive.
PVI displays a numeric representation of the changes to the pleth waveform on the pulse oximeter and allows clinicians to track and trend these changes over time as well as a Diagnostic Plethysmograph that maintains the morphology of the true pleth for clinicians to view.
