Precautions for Cardioversion

WARNINGS: Cardioversion should only be delivered by trained healthcare professionals.
When performing synchronized cardioversion through external paddles, you should not use paddles
as your monitoring lead in Wave Sector 1. Artifact introduced by paddle movement may resemble an
R-Wave arrow and trigger a defibrillation shock. Use external paddles as a monitoring lead for
Synchronized Cardioversion only if no other lead source is available and you are in an emergency
Incorrect timing of Synchronized Cardioversion could occur if the patient has an internal pacemaker
with pacemaker tails large enough to be detected as an R-Wave.
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.
Remain attentive to the patient during the delivery of therapy.
Keep hands and feet clear of the paddle electrode edges. Use your thumbs to depress the shock
buttons on the paddle handles.
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 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 during defibrillation.
NOTES: Successful cardioversion 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.
Synchronized Cardioversion should be turned off unless you specifically intend to perform
synchronized cardioversion. Sync Mode can prevent the delivery of defibrillation in situations
involving cardiac arrest.
If you enter Pacing Mode, Sync settings are turned off.
Use only approved lead sets with the Efficia DFM100. Failure to do so may introduce noise and
result in intermittent
