Perfusion index pvi
Perfusion index (PI) is a relative assessment of the pulse strength at the monitoring site. The plethysmographic variability index (PVI, pleth variability index) is a The calculation of PVi (Pleth Variability Index) is based on the measured changes in Pi (Perfusion Index). Improper titration of fluid can lead to hypovolemia or Perfusion Index (PI) and Pleth Variability Index (PVI) in Patients With Interscalene Blocks in Orthopedic Surgery (PI-PVI).

PVi ® is a measure of the dynamic changes in the Perfusion Index (Pi) that occur during one or more complete respiratory cycles. Pi reflects the amplitude of the pulse oximeter waveform and is calculated as the pulsatile infrared signal (AC or variable component), indexed against the non-pulsatile infrared signal (DC or constant component).

Pleth variability index (PVI) is a measure of the variability of the perfusion index, which occurs during breathing cycles. Mathematically it is calculated as (Pi max - Pi min )/Pi max × 100% , where the maximum and minimum Pi values are from one or many breathing cycles. [54]

The pleth variability index (PVI), which is derived from respiratory variations in the peripheral perfusion index (PI), provides clinicians with a numerical value obtained noninvasively, automatically, and continuously [6–8]. However, whether the changes in PVI detected at the end of the finger can mirror the changes of intravascular volume or cardiac preload remains unclear. Perfusion Index or PI is the ratio of the pulsatile blood flow to the non-pulsatile static blood flow in a patient's peripheral tissue, such as finger tip, toe, or ear lobe. Perfusion index is an indication of the pulse strength at the sensor site. condition, or who are anesthetized, undergoing surgery, or in labor. The perfusion index (PI) is the ratio of the pulsatile blood flow to the nonpulsatile or static blood in peripheral tissue. Perfusion Index thus represents a noninvasive measure of peripheral perfusion that can be continuously and noninvasively obtained from a pulse oximeter. Perfusion Index (Pi) – Strength of blood flow to the finger to indicate changes in blood circulation. Respiration Rate (RRp™) – Number of breaths per minute to indicate how well your heart and lungs are functioning or how quickly you recover after exercise. "PVI demonstrated high accuracy in discriminating fluid responders from non-responders—providing a unique opportunity to better manage a patient's fluid volume to optimize cardiac performance and organ perfusion."
