Defibrillator Troubleshooting
Table 7-3 lists common issues with defibrillation and their associated corrective action.
Table 7-3. Defibrillator Issues
Symptom Corrective Action
Defibrillator does not charge. 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 (semiautomatic mode only). Verify the
rhythm.
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. (Refer to “Optional Maintenance
for Technical Professionals” on page 7-7.)
If the message CHECK DEFIB PADS appears, check
and correct the attachment or position of the
electrodes.
Message:
CHECK DEFIB PADS Ensure that the defibrillation electrode pads are making
proper skin contact and that patient does not have
excessive hair beneath electrodes.
If message persists, change the defibrillation cable.
Message:
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.
