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
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
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
