Note: If no compressions have been detected for at least 3 seconds or if the compressions fall
below the display range of rate and depth indicators, the rate Depth and Rate fields
display dashes (----).
Rate and Depth Measurements
The rate and depth measurements are displayed in green (good) while the operator meets or
exceeds the respective rate and depth targets. When CPR performance is diminished, the rate
measurement is displayed in yellow (needs improvement) when it drops below the target rate.
Likewise, the depth measurement is displayed in yellow when it drops below the target depth.
This color coding is intended to assist the rescuer in determining whether chest compression
rate or depth should be increased or maintained.When an appropriate rate and depth are
achieved, these labels return to green.
CPR Release Indicator
The CPR Release Indicator is intended to provide feedback on the rescuer’s ability to fully lift
his hands off the sternum during the upstroke of the compression. The release indicator is filled
when rescuers release compressions more quickly, whereas the indicator will only fill partially
if chest compression release is slow. In addition, a text prompt to FULLY RELEASE is
periodically displayed while compressions are being performed.
Chest Compression Indicator
This diamond-shaped figure provides a quick, overall indicator of how well the rescuer's
combined rate and depth of chest compressions match the AHA/ERC recommendations for
adult CPR.
The CPR Compression Indicator, also known as Perfusion Performance Indicator (PPI), is first
displayed as an empty diamond. This indicator starts to fill as compressions begin (filling from
the inside), and becomes completely filled when consistent chest compression depth exceeding
(AHA/ERC 2005: 1.75, AHA/ERC 2010: 2.0) inches and rate exceeding 90 compressions per
minute (cpm) are achieved simultaneously. Should the chest compression rate or depth begin to
fall below the configured target levels, the indicator will only partially fill to indicate the need
for more rigorous efforts. Following the cessation of compressions, the indicator’s fill level
gradually decreases until a hollow outline is displayed after a short period of time.
