• Impedance is the resistance between the electrode pads that the defibrillator must overcome to
deliver an effective discharge of energy. The degree of impedance differs from patient to patient
and is affected by several factors including the presence of chest hair, moisture, and lotions or
powders on the skin. If the “Shock canceled. Press pads firmly to patient's bare skin” voice prompt is
provided, make sure that the patient’s skin has been dried and chest hair has been clipped. If the
prompt persists, change the electrode pads.
