5.2 AED Procedure
• Anterior - lateral placement for adult patients, and anterior-posterior placement for pediatric
patients are recommended placements for defibrillation with electrode pads.
• For defibrillation of pediatric patients under 8 years, pediatric electrode pads should be used.
• If pediatric electrode pads are not available, the adult electrode pads may be used instead, and set
Patient Category to Ped.
• The Shock button must be pressed to deliver a shock. The equipment will not automatically deliver a
shock.
• Impedance is the resistance found between electrode pads or external paddles. To deliver an
effective discharge of energy, the impedance must be overcome. The degree of impedance varies
with the patient. It is affected by other factors, such as the presence of chest hair, moisture, and
lotions or powders on the patient skin. If the “Impedance too high. Shock not delivered” message
appears, make sure that the patient’s skin has been dried and that any chest hair has been clipped. If
the message persists, replace the electrode pads or the pads cable with a new one.
