Corrective Action
(Semiautomatic mode only) The patient's ECG rhythm
is not shockable because it is not either ventricular
fibrillation (VF) or wide-complex ventricular tachycardia
(VT), or is VF with amplitude less than 100 V.
Confirm that the defibrillation cable is plugged in and
the pads are attached to the patient.
Install a fully charged battery pack.
Install a fully charged battery pack.
A fully charged defibrillator automatically disarms itself
after 60 seconds in manual mode or 30 seconds in
semiautomatic mode. Charge the defibrillator again and
deliver the shock while the charge-ready tone sounds.
The Shock button was pressed before the unit was fully
charged. Wait for the charge-ready tone and a flashing
Shock button before pressing and holding the Shock
button.
Under certain circumstances, a patient might not
display a physical reaction when energy is delivered.
Replace the electrodes if they are dried out or expired.
Ensure that the electrodes are making proper contact
with the patient's skin.
Test the defibrillator.
If the prompt CHECK DEFIB PADS appears, check and
correct the attachment or position of the electrodes.
Ensure that the defibrillation electrode pads are making
proper skin contact and that the patient does not have
excessive hair beneath electrodes.
If message persists, change the defibrillation cable.
Check for proper application and adhesion of the
defibrillation electrode pads.
Ensure that no one is touching the patient and that the
patient is motionless during ECG analysis.
