SECTION 5
AUTOMATED EXTERNAL
DEFIBRILLATOR (AED) OPERATION
Introduction
This section describes the recommended method of
operation. If your local protocol requires a different
procedure, follow that protocol.
The unit is capable of analyzing a patient’s ECG rhythm
in two different ways. The first mode of analyzing is
always active in the background of the semi-automatic
mode (continuous analysis) when MFE Pads or ECG
cable and electrodes are in use. The other mode of
analyzing is user activated analysis, initiated by pressing
the ANALYZE button.
User activated analysis of a patient’s ECG can only be
performed when:
• MFE Pads are connected.
• MFE Pads are firmly attached to the patient to reduce any
electrode noise or artifact.
• SELECTOR SWITCH is turned to ON.
In semi-automatic mode, pressing the ANALYZE button
causes the unit to begin an analysis of the patient’s ECG
in order to determine if a shockable rhythm is present.
This analysis consists of 3 consecutive 3-second ECG
rhythm analyses. If at least 2 of the 3 analyses determine
that the patient has a shockable rhythm, the unit will
automatically charge to the pre-configured energy level
and prompt the operator to shock the patient. If 2 or more
of the three 3-second ECG analyses do not detect a
shockable rhythm, the unit will alert the operator that no
shock is advised.
Following each shock, the continuous analysis function
resumes operation and will issue a “CHECK PATIENT”
message and audio prompt if a shockable rhythm is
detected. (Continuous analysis runs on a sliding
12 second window of ECG data, producing a result every
3 seconds. If 3 out of 4 3-second segments are
shockable, the “CHECK PATIENT” message is issued.)
The “CHECK PATIENT” message and voice prompt will
be inhibited for 70 seconds, however, following the
completion of a user activated analysis or discharge.
AED Semi-Automatic Operation
Determine Patient Condition Following Medical Protocols
Verify:
• Unconsciousness
• Absence of breathing
• Absence of pulse
Begin CPR following medical protocols
Request additional assistance.
Prepare Patient
Remove all clothing covering the patient's chest. Dry
chest if necessary. If the patient has excessive chest
hair, clip it to ensure proper adhesion of electrodes.
Attach the MFE Pads according to instructions on the
electrode packaging.
Ensure that all MFE Pads are making good contact with
the patient’s skin and are not covering any part of the
ECG electrodes.
Connect MFE Pads to the multi-function cable if not
preconnected.
The message “CHECK PADS” will be displayed and
energy will not be delivered if the MFE Pads are not
When Multi-function Electrode (MFE) Pads are used, the patient
connection is considered to be defibrillation protected Type BF.
WARNING
• Do not use the unit’s Advisory function on patients under
8 years of age.
