Pleth Variability Index (PVi) is dynamic index between 0-100 which measures the relative variability of the pleth waveform noninvasively detected from a pulse oximetry sensor. It uses the detected pleth amplitudes to automatically calculate the dynamic changes that occur during the respiratory cycle.
