Using Real CPR Help
®
The CPR-D•padz include a sensor that detects the rate and depth of CPR chest compressions. This
sensor is placed (as part of the electrodes application) on the victim’s chest so that it is located between
the rescuer’s hands and the victim’s lower sternum during chest compressions. When the rescuer
performs CPR compressions, the sensor detects their rate and depth and sends the information to the
AED Plus unit. When used with CPR-D•padz, the AED Plus monitors the depth and rate of CPR chest
compressions. It provides a CPR metronome function designed to encourage rescuers to perform chest
compressions at the AHA/ERC recommended rate of 100 compressions per minute (CPM) as well as
voice and visual prompts to encourage a minimum compression depth of 2 inches for adult victims.
WARNING! Real CPR Help is intended for use on adult victims only; do not use on victims
under 8 years of age.
The adaptive metronome function is disabled during periods when CPR should not be performed (for
example, during ECG analyses and defibrillation shock sequences). During periods when CPR may be
indicated, the metronome begins issuing audible beeps following detection of the rescuer’s first few
compressions. The beeps continue automatically (at rates described below) until a few seconds after
chest compressions are halted by the rescuer or until the recommended “CPR period” ends (2 minutes
for AHA and ERC protocols). If the rescuer ceases chest compressions during the CPR period,
metronome beeps stop within a few seconds after compressions are halted. Audible beeps resume
during the CPR period following any re-initiation of CPR compressions. If no CPR compressions are
detected during “CPR periods”, the AED Plus periodically re-issues the CONTINUE CPR prompt.
The rate of beeps issued by the AED Plus adaptive metronome function adapts to the rescuer’s actual
chest compression rate. The metronome will beep at 100 CPM when chest compressions are delivered
at greater than 80 compressions per minute (CPM). Should the rescuer fail to deliver compressions at
80 CPM or greater, the metronome will beep at a rate that is approximately 15 CPM higher than the
rescuer’s actual rate. This increased metronome rate is intended to encourage the rescuer to increase
his/her chest compression rate until the recommended 100 CPM rate is achieved. The metronome beeps
at a minimum rate of 60 CPM in cases where the rescuer’s compression rate is substantially below
60 CPM.
During CPR, the AED Plus may issue one or more audible prompts based on the depth of chest
compressions detected. When Real CPR Help determines that compression depth is consistently less
than 2 inches, a PUSH HARDER prompt will be issued. A GOOD COMPRESSION prompt will be
issued if the rescuer responds by increasing compression depth to 2 inches or more.
The AED Plus unit can be configured to display the FULLY RELEASE text prompt to remind the user
to lift the hands off the chest during CPR. By default, this text prompt is not enabled.
