“Analyzing heart rhythm”
“Analyzing”
Analyzing Rhythm
Analyzing
Purpose:
The DDU-2000 Series AED is actively analyzing the patient’s ECG signal. The AED will continue analyzing
until it has determined whether a rhythm is shockable or non-shockable or if analyzing is interrupted for some reason.
“Do not touch the patient”
Do Not Touch Patient
Purpose:
The DDU-2000 Series AED is trying to analyze the patient’s heart rhythm. The operator should not touch
the patient. This prompt will be spoken at the beginning of the analysis period.
“Analyzing interrupted”
Analyzing Interrupted
Purpose:
The DDU-2000 Series AED has determined that accurate ECG analysis is not possible and has ceased
analyzing. The operator is prompted to resolve the problem. (Refer to the “
Motion/Interference Prompts
” and the
“
Pad Connection/Pad Application Related Prompts
” section in this chapter.) Once the problem is resolved, the unit
will enter analysis mode again.
“No shock advised”
No Shock Advised
Purpose:
The DDU-2000 Series AED has determined that a shock is not required. The unit will
NOT
charge and
the SHOCK button on semi-automatic units will
NOT
be enabled. The user will be prompted to begin CPR.
“Shock advised”
Shock Advised
Purpose:
The DDU-2000 Series AED has determined that a shock is recommended and the unit will begin
charging in anticipation of delivering a defibrillation shock.

“Charging”
Charging
Purpose:
The DDU-2000 Series AED has determined that a shock is recommended and is charging the unit in
anticipation of a defibrillation shock. Analysis will continue during this phase. A tone may sound to indicate
charging progress. If the unit detects a rhythm change to a non-shockable one, charging will abort and the user
will be prompted to begin CPR.
Note:
At any time during the charging process or after the AED has been charged, the operator may disarm the
unit by pressing the ON/OFF button for approximately 2 seconds to power off the AED.
“Stand clear”
Stand Clear
Purpose:
The DDU-2000 Series AED is charging and the operator and others should stand clear of the patient.
Analysis will continue during this phase and analyzing prompts will continue to be displayed. A tone may sound
to indicate charging progress. If the unit detects a rhythm change to a non-shockable one, charging will abort
and the user will be prompted to begin CPR.
“Press flashing SHOCK button”
(DDU-2300 and DDU-2450 ONLY)
Press SHOCK Button
Purpose:
The semi-automatic AED has fully charged, the heart rhythm analysis algorithm still indicates that a
shock is recommended, and the unit is ready to deliver a shock. The operator should press the SHOCK button to
deliver the shock. The SHOCK button will flash during this phase and will cancel after 30 seconds.
Important
: Semi-automatic AEDs will not automatically deliver a shock – the user must press the SHOCK button.
“Shocking in 3, 2, 1”
(DDU-2200 ONLY)
Delivering Shock
Purpose:
This indicates that the DDU-2200 AED has fully charged, that the heart rhythm analysis algorithm still
indicates a shock is recommended, and the unit is about to deliver a shock. The SHOCK Required Indicator will
flash during this time. The shock will automatically be delivered after the count reaches "1."
Do not touch the
patient during this time.
“Shock ‘x’ delivered”
Shock “x” Delivered
Purpose:
The DDU-2000 Series AED has delivered the shock. The ‘x’ indicates the number of shocks that have
been delivered since the unit was turned on. After each shock, the AED will enter Post-Shock CPR mode.
