5: AED Mode Option Using AED Mode to Defibrillate
68
Step 1 - Turn the Therapy Knob to AED
When the Efficia DFM100 is turned to AED, it announces and displays the patient category.
Confirm you have the correct category active for the patient. If not, use the Patient Category button
to select the correct category.
The device also checks to see if the Therapy cable and multifunction electrode pads are properly
connected. If the:
• Therapy cable is not properly attached, you are prompted to “
Plug in Connector” with a
prompt and graphic illustration on the screen.
• Multifunction electrode pads are not connected to the Therapy cable, pads are not applied
to the patient or pads are not making proper contact with the patient’s skin, you are
prompted to “
Insert connector firmly. Apply pads.”
Follow the audio and visual prompts to correct the issues. When properly connected, AED Mode
automatically begins shock analysis. If the patient category is changed when shock analysis is in
progress, you do not need to abort the analysis in progress and restart a new one. The algorithm is
not sensitive to patient category.
Step 2 - Follow Screen and Voice Prompts
Once an ECG is detected through the multifunction electrode pads, the Efficia DFM100 warns you
not to touch the patient and automatically analyzes the patient’s heart rhythm.
NOTE: The AED algorithm only looks at the ECG for analysis. It does not use any other data, even if the
option is active in AED Mode.
WARNING: Handling or transporting the patient during ECG rhythm analysis can cause an incorrect or delayed
diagnosis. Under these circumstances, if the Efficia DFM100 issues a “
Shock Advised” command,
keep the patient as still as possible for at least 10 seconds so the device can reconfirm the rhythm
analysis before pressing the orange Shock button to deliver a shock.
The AED Mode algorithm can return one of the following results:
• Shock Advised - If a shockable rhythm is detected, the Efficia DFM100 automatically charges
to the preconfigured Joule setting (default is 150J) if the Adult patient category is selected (see
“AED Settings” on page 154) or 50J if in the Infant/Child category. Charging is accompanied
by voice and screen prompts. When the device is fully charged, a steady high-pitched tone
sounds, and the orange Shock button flashes.
Heart rhythm analysis continues while the Efficia DFM100 charges. If a rhythm change is
detected before the shock is delivered, and a shock is no longer appropriate, the defibrillator
disarms itself.
NOTE: When fully charged, you can disarm the device at any time by turning the Therapy knob off the
AED position. Resume AED monitoring by turning the Therapy knob back to AED.
• No Shock Advised (NSA) - If a shockable rhythm is not detected, the Efficia DFM100 tells you
“No shock advised.” Follow your institution's protocol for a No Shock Advised alert. The device’s
next steps are determined by the No Shock Advised Action configuration choice. If the
configuration is set to:
- Monitor - The Efficia DFM100 monitors the ECG and automatically resumes analysis if
a potentially shockable rhythm is detected. You are periodically prompted to press
and to begin CPR if CPR is indicated. The frequency of these prompts is defined in the
Monitor Prompt Interval configuration choice. You may press
to suspend monitoring
and administer CPR. The pause period is defined by the CPR Timer configuration choice.
