Unique Parameters and Indicators
- Signal IQ® (SIQ)
- Located under the plethysmographic waveform. The height of the vertical line provides an assessment of the confidence in the SpO2 value displayed.
- Plethysmographic (Pleth) Waveform
- Real-time graphical representation of changes in volume of arterial blood with each pulse.
- Perfusion Index (Pi)
- The ratio of the pulsatile blood flow to the non-pulsatile blood in peripheral tissue used to measure peripheral perfusion.
- Pleth Variability Index (PVi)
- A measure of the dynamic changes in the perfusion index (Pi) that occur during the respiratory cycle.
- Respiration Rate from the Pleth (RRp)
- A measure of respiration rate based on changes in the plethysmographic waveform. The unit of measure is respiration per minute (RPM).
