Real CPR Help Field
Whenever OneStep CPR, or OneStep Complete electrodes are connected to the R Series
defibrillator, the unit illuminates the Real CPR Help field in the upper center portion of the
display. This field includes the indicators described in the next sections.
CPR Index (Optional/Adult Only)
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.
Before chest compressions begin (and after each shock), the CPR Index is displayed as a
hollow outline. This index starts to fill from the center out as compressions begin, and becomes
fully filled when consistent chest compression depth exceeding 1.5 or 2 inches, depending on
the configuration, and rate exceeding 90 compressions per minute (cpm) are simultaneously
achieved. Should the chest compression rate or depth begin to fall below the AHA/ERC
recommended levels, the Index will only partially fill to indicate the need for more vigorous
efforts. Following the cessation of compressions, the Index’s fill level gradually decreases until
a hollow outline is displayed after a short period of time.
When complete filling of the CPR Index has not been achieved due to diminished compression
rate or depth, and the CPR Dashboard is configured Off, the R Series will display the words
RATE and/or DEPTH to assist the rescuer in determining whether chest compression rate or
depth should be increased. When an appropriate rate or depth has been achieved, 80 cpm and
1.5 or 2 inches, respectively, one or both of these words will disappear from the display.
This feature is unavailable while using Pediatric CPR electrodes.
CPR Idle Time Display
This display indicates the elapsed time in minutes and seconds since the last detected chest
compression. When compressions are being delivered, this time display will be blanked. Three
seconds following the cessation of compressions, the display will illuminate and show the
elapsed time since the last detected compression. If no compressions have been delivered for
more than 20 minutes, dashes (---) will be displayed in this time field.
CPR Rate and Depth Display
If the CPR Dashboard is configured On and the CPR Idle Time is not displayed, the Rate and
Depth values will be displayed in the Real CPR Help field. The values will be highlighted and
displayed in red if they are below the appropriate values (adult CPR electrodes only).
