5: AED Mode Option
Precautions for AED Therapy
WARNINGS: The AED algorithm is not designed to handle erratic spiking problems caused by a properly or
improperly functioning pacemaker. In patients with cardiac pacemakers, the Efficia DFM100 may
have reduced sensitivity and not detect all shockable rhythms.
Use only pads that are approved for use with the Efficia DFM100. Use of non-approved pads could
affect performance and results. See
list of supported pads.
For adults in AED Mode, the multifunction electrode pads must be in the anterior-anterior position
shown on the packaging. For Infant/Child patients, the pads can be in the anterior-posterior
Do not allow multifunction electrode pads to touch each other or to touch other ECG monitoring
electrodes, lead wires, dressings, etc. Contact with metal objects may cause electrical arcing and
patient skin burns during defibrillation and may divert current away from the heart.
During defibrillation, air pockets between the skin and multifunction electrode pads may cause
patient skin burns. To help prevent air pockets, make sure the pads completely adhere to the skin.
Do not use dried out pads. Do not open pads package until just prior to use.
Never touch the patient or any equipment connected to the patient (including the bed or gurney)
during analysis and defibrillation.
Avoid contact between the patient and conductive fluids and/or metal objects such as the gurney.
Medical electrical equipment which does not incorporate defibrillator protection should be
disconnected before defibrillation.
NOTES: Successful resuscitation depends on many variables specific to the patient's physiological state and
the circumstances surrounding the patient event. Failure to have a successful patient outcome is not
a reliable indicator of defibrillator/monitor performance. The presence or absence of muscular
response to the transfer of energy during electrical therapy is not a reliable indicator of energy
delivery or device performance.
Impedance is the resistance found between the defibrillator's pads when applied to the patient's body
the device 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. The low-energy SMART biphasic waveform is an
impedance-compensating waveform that is designed to be effective across a wide range of patients.
However, if you receive a
washed and dried and that any chest hair has been clipped. If the message persists, change the pads
and/or Therapy cable.
The Efficia DFM100's SMART Analysis algorithm detects internal pacemaker pulses that are 2.5 ms
or less in duration and removes these pulses so that they are not counted by the algorithm.
Perform all routine diagnostic tests to verify that voice prompts are operational during Operational
Check and according to your organization's protocol.
