Defibrillator Troubleshooting
Table 2-3 lists common issues with defibrillation and their associated corrective action.
Table 2-3. Defibrillator Issues
Symptom Corrective Action
Defibrillator does not charge. (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
μV.
Confirm that the defibrillation cable is plugged in and
the pads are attached to the patient.
Install a fully charged battery pack.
Defibrillator takes more than 15 seconds
to charge. Install a fully charged battery pack.
Energy does not discharge when the
Shock button is pressed. 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.
No apparent energy delivery to patient. 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.
;
CHECK DEFIB PADS
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.
;
ANALYSIS HALTED
KEEP PATIENT STILL
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.
