Perfusion Index (PI) Delta Alarm Overview
The PI Delta Alarm is a user-selectable feature which allows a clinician to request an audible
and visual alarm if perfusion at the monitored site decreases by a specified level (delta) over
a specific period of time.
Perfusion Index gives an indication of the level of perfusion at the monitored site. The
Radical-7 measures perfusion at the SpO2 site by comparing the pulsatile signal to the
non-pulsatile signal, and expressing that ratio as a percentage. PI has been clinically proven
to be useful as a predictor of the level of illness in neonates and adults and that PI may
change dramatically in response to sympathetic changes caused by inhalational agents and
pain stimulation*. If PI decreases over time, there may be underlying physiological reasons
that may need to be addressed.
The PI Delta provides an audible and visual alert to important changes in perfusion compared
to the patient’s baseline PI rate. The baseline is set by the Radical-7 once the user has
enabled the alarm. The baseline is 30 seconds of currently averaged PI. The feature includes
a user-selectable PI Delta Alarm. This allows the clinician to request an audible and visual
alarm if perfusion at the monitored site decreases by a specified level (delta) over a specified
window of time. Three of the variables are selectable by the user within established ranges as
noted in PI Delta Settings on page 103.
