This chapter explains how to prepare for and perform defibrillation or asynchronous cardioversion
on the Efficia DFM100 using multifunction electrode pads, external paddles and internal paddles.
Chapter 7 "Synchronized Cardioversion"
on page 85 for information on synchronized
Defibrillation therapy is the definitive method for termination of lethal arrhythmias.The Efficia
DFM100 provides this therapy through the application of a biphasic pulse of current to the heart.
This electrical energy is transferred through attached paddles or disposable multifunction electrode
pads applied to the patient's bare chest. Internal paddles for open-chest intrathoracic defibrillation
can also be used.
In Manual Defibrillation Mode, the entire defibrillation process is under your control. You must
assess the ECG, decide if defibrillation or cardioversion is indicated, select the appropriate energy,
charge the Efficia DFM100 and deliver the shock. Text messages on the display provide relevant
information throughout the process. Be attentive to these messages when displayed.
The ECG strip and Event Summary are easily annotated with information using the Mark Event
on page 43.
Monitoring alarms are available in Manual Defibrillation Mode but they are turned off by default.
To activate alarms, press the Alarm button
. Alarms are reactivated once the Therapy knob is
moved to Monitor, an energy setting or Pacer or the Sync button is pressed.
The Efficia DFM100 Manual Defibrillation Mode can be used on both adult and infant/child
patients. Use the Patient Category
button to switch categories.
