8.6 PI (Perfusion Index)*
PI is a numeric value indicating perfusion level. It reflects the perfusion level at the monitoring site.
As the measurement of SpO
2
is based on the pulsation caused by the blood flow through the
vessel, PI is in relation to the strength of the pulse. Also, you can use PI as a signal quality
indicator for the measurement of SpO
2
.
PI is indicated by a value ranging from 0 to 10. The bigger the value is, the better the perfusion
and the signal quality will be. The perfusion level and the signal quality are at their maximum
when the value reaches 10. When PI is below 2, it indicates the low perfusion and the poor signal
quality at the monitoring site; you need to reposition the sensor or find a better site.
The PI value will be displayed on the SpO
2
waveform area.

Setup menu:
 Pulse Volume: Set it to level 0 ~ 5.
 Pitch Tone: Set it to ON or OFF. Pulse frequency has positive correlation with measurement
value.
 PI: If it is set to ON, the perfusion index will be presented on the main interface. If it is set to
OFF, the perfusion index is unavailable on screen.
