Heart Rhythm Analysis Prompts
Voice Text
“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 and also if motion or interference
has been detected.
“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 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.
Shock Related Prompts
Voice Text
“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 will 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.
“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 will 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”
Press SHOCK Button
Purpose: The DDU-2000 Series 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: The DDU-2000 Series AED will not automatically deliver a shock – the user must press the SHOCK button.
“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.
(AHA/ERC 2010 Protocol)
“Shock cancelled”
Shock Cancelled
Purpose: The DDU-2000 Series AED has aborted shock mode. If while waiting for the SHOCK button to be
pressed, the unit detects a rhythm change to a non-shockable rhythm, the unit will cancel the shock. Also, if the
SHOCK button is not pressed within 30 seconds of the initial “press flashing SHOCK button” prompt, the unit
will automatically cancel the shock.
