Intraoperative Pleth Variability Index (PVI) Variability

Stopped early

Conditions studied: Intraoperative Monitoring

In brief

Pleth Variability Index (PVI) is a variable that is derived from photoplethysmography (PPG) signal. It is used as a surrogate for intravascular volume status intraoperatively. PVI can have significant amount of baseline variability which appears to oscillate at a very low frequency (5-10 minute cycles). This study aims to investigate the origin of these baseline oscillations.
