11 Observe the patient and the ECG rhythm. If an additional shock is necessary, repeat the
procedure beginning at Step 6.
Note: If the
ABNORMAL ENERGY DELIVERY
message appears and the shock is not
effective, increase energy, if necessary, and repeat shock. (Also refer to page 4-24 .)
CPR Metronome
When CPR is required during cardiac arrest, the CPR metronome provides audible prompts that
guide the user to deliver CPR with proper timing in accordance with the 2010 American Heart
Association and European Resuscitation Council CPR guidelines.
CPR Metronome Warnings
Note: The CPR metronome is a tool to be used as a timing aid during CPR. Assess the
patient at all times and provide CPR only when indicated. Provide CPR according to your
training and protocols.
How the CPR Metronome Works
The metronome provides audible “tocks” at a rate of 100/minute to guide the rescuer in
performing chest compressions. The metronome also provides audible ventilation prompts
(either a tone or verbal “ventilate”) to cue the rescuer when to provide ventilations. The
metronome prompts the rescuer to perform CPR at the selected compression to ventilation (C:V)
ratio.
Age-Airway Considerations
The default C:V ratio for the metronome (in both AED and Manual modes) is Adult - No Airway
(30:2) because most patients in cardiac arrest are adults who have an initially unsecured airway.
In Manual mode, the user can choose the most appropriate C:V ratio based on the patient’s age
and current airway status. The Age-Airway selection determines the C:V ratio of the metronome
sounds. The default C:V ratios are shown in Table 4-2.
* No Airway = No artificial airway in place
** Airway = Advanced artificial airway in place
*** Youth = Pre-pubescent child
Note: The compression-to-ventilation ratio selections can be set up according to local
medical protocols. For more information, refer to "CPR Metronome Setup Menu," page 8-8 .
WARNING!
CPR Delivered When Not Needed.
The metronome sounds do not indicate information regarding the patient’s condition. Because
patient status can change in a short time, the patient should be assessed at all times. Do not
perform CPR on a patient who is responsive or is breathing normally.
