NOTE

Use the defibrillator pads before the expiration date. If the pads are found expired, by checking either the
expiration date on the pads package or the alarm message displayed on the screen, replace the pads
immediately. In emergency, if there are no spare pads nearby, proceed patient treatment with the pads
and ignore pads related alarm messages.

Do not use anterior-posterior pads placement (multifunction electrode pads placed on the patient’s chest
and back) for adult patients. The AED algorithm used by the equipment has not been validated using this
placement.

Use pediatric pads for pediatric patients. If you are using adult pads for pediatric patients, select
and set the patient type to pediatric and follow the instructions on the screen to apply pads.

Motion artifact may delay analysis or affect the ECG signal resulting in an inappropriate shock or no shock
advised message. Keep the patient still during ECG rhythm analysis.

The Shock button must be pressed to deliver a shock. The equipment will not automatically deliver a
shock.

Impedance is the resistance between the defibrillator’s pads hat 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
“Impedance too high. Charge removed” message appears, make sure that the patient’s skin has been
washed and dried and that any chest hair has been clipped. If the message persists, change the pads.

Most pediatric cardiac arrests are asphyxial, and the resuscitation from asphyxial arrest is best
accomplished by a combination of ventilations and chest compressions. Make sure proper CPR is
performed on the patient when waiting for defibrillation equipments or advance life support. Or follow
your local protocol.
5.5 Shock Advised
If a shockable rhythm is detected, the equipment automatically charges to the pre-configured energy level for the
current patient type. A charging tone is sounded, and the Shock button flashes when the equipment is fully charged.
Heart rhythm analysis continues while the equipment charges. If a rhythm change is detected before the shock is
delivered and a shock is no longer appropriate, the stored energy is removed internally.
If the patient type is changed or pads malfunction detected during charging, the charge will be removed.
Once you are prompted "Do Not Touch Patient! Press Shock Button", if you do not do so within 30 seconds, the
equipment disarms itself and resumes analyzing.
