  • Many pulse oximetry technologies display a processed and filtered representation of the photoplethysmosgraphic waveform. Each manufacturer uses unique proprietary algorithms to calculate the waveform displayed on the pulse oximeter. Masimo has extracted and processed information from the waveform to create two physiologic indices, perfusion index (PI) and pleth variability index (PVI). PI is calculated by indexing the infrared (IR) pulsatile signal against the nonpulsitile signal and expressing… CONTINUE READING
