PI
Perfusion Index, or PI, is a relative assessment of the
perfusion at the monitoring site. PI is displayed on a 10
segment LED bar, ranging from < .1% (very weak perfusion)
to >5% (strong perfusion). The highest LED will remain lit
continuously to allow a PI level to be viewed. The Perfusion
Index is the ratio of the AC (pulsatile) to DC (non-pulsatile)
components of the IR (Infrared) signal where the AC and DC
components correspond to the pulsatile and non-pulsatile
amounts of blood, respectively.
