4.7 No Shock Required
If the DDU-120 AED ECG analysis algorithm has determined that a shock is not required, the
operator will be prompted to begin CPR, if needed, for a period of two minutes. The unit will not be
monitoring the patient’s ECG rhythm during this two minute CPR period.
During this two-minute period, the AED will not advise the user to “stop motion” even if motion
is present. During the two-minute period, the AED will announce time remaining in 15-second
intervals. At the end of the two-minute period, the unit will enter normal Analyzing mode.
No Shock Required Voice Prompts:
“It is safe to touch the patient” – This indicates that the DDU-120 AED analysis algorithm
has determined that no shock is required.
The user will be prompted to begin CPR, if needed, for
a period of two minutes. The “analyzing” LED will remain off to indicate that background rhythm
monitoring has been suspended.
“Check airway”, ”Check breathing” – This indicates that the user should check the condition
of the patient in order to determine if it is appropriate to perform CPR.
“If needed, begin CPR” – This indicates that the user should begin CPR, if needed, for two
minutes. The unit will not be monitoring the patient’s ECG rhythm during this two minute CPR
period. The “analyzing” LED will remain off to indicate that background rhythm monitoring has been
suspended.
“Continue for ‘x’ seconds” or “Continue for 1 minute ‘x’ seconds” – This indicates
that the user should continue CPR, if needed, for ‘x’ more seconds or, for 1 minute and ‘x’ more
seconds, respectively. The unit will not be monitoring the patient’s ECG rhythm during this two
minute CPR period. The “analyzing” LED will remain off to indicate that background rhythm
monitoring has been suspended.
“Continue” – This indicates that the user should continue CPR, if needed. This phrase is spoken
between the “continue for ‘x’ seconds” or “continue for 1 minute ‘x’ seconds” prompts to let the
operator know that the unit is still operating normally. The unit will not be monitoring the patient’s
ECG rhythm during this two minute CPR period. The “analyzing” LED will remain off to indicate that
background rhythm monitoring has been suspended.
“Continue for 5, 4, 3, 2, 1,” “Stop CPR” – This indicates that the user should finish
performing CPR. This phrase is spoken during the last several seconds of the two-minute CPR
period to let the operator know that the unit is still operating normally and that the two-minute
period is ending.
