The Defibtech DDU-120E is an automated external defibrillator (AED) designed to be easy to use in emergency situations. Here's a step-by-step procedure:
1. Ensure Scene Safety and Assess the Victim
- Ensure scene safety: Before approaching, make sure the area is safe for you and the victim.
- Check for responsiveness: Gently tap the person's shoulder and shout, "Are you okay?"
- Activate emergency response: If the person is unresponsive, immediately call 911 (or your local emergency number) or ask a bystander to do so.
- Check for breathing: Look for chest rise and fall for no more than 10 seconds. Gasping is not considered normal breathing.
2. Turn on the AED
- Press the green "ON" button. The AED will begin providing voice prompts to guide you through the process.
3. Prepare the Victim's Chest
- Expose the chest: Remove or cut away any clothing covering the person's chest.
- Dry the chest: If the chest is wet, quickly wipe it dry with a towel or cloth.
- Remove excessive hair: If there is excessive chest hair that may prevent the pads from sticking, quickly shave the area where the pads will be placed (if a razor is available).
4. Apply the AED Pads
- Open the AED pad package.
- Peel off the backing from the pads.
- Place the pads on the person's bare chest as shown in the diagrams on the pads themselves.
- One pad should be placed on the upper right chest, below the collarbone.
- The other pad should be placed on the lower left side of the chest, below the armpit.
- Firmly press the pads onto the skin.
5. Follow the AED Prompts
- "Analyzing heart rhythm": The AED will analyze the person's heart rhythm. During this time, ensure no one is touching the person.
- "Shock advised": If the AED detects a shockable rhythm, it will instruct you to deliver a shock.
- Ensure no one is touching the person.
- Press the flashing "Shock" button.
- "No shock advised": If the AED determines that a shock is not needed, it will instruct you to begin CPR.
6. Perform CPR as Instructed
- The AED will provide voice prompts to guide you through CPR.
- Typically, this involves cycles of 30 chest compressions and 2 rescue breaths.
- Continue CPR until:
- The person shows signs of life (e.g., breathing).
- Emergency medical services (EMS) arrive.
- The AED instructs you to stop.
Important Considerations:
- Do not touch the person while the AED is analyzing or delivering a shock.
- If the person starts to show signs of life (e.g., breathing), do not remove the AED pads. Wait for EMS to arrive.
- If the first shock is unsuccessful, the AED will typically prompt you to continue CPR and may advise further shocks.
- For children under 8 years old or weighing less than 55 pounds (25 kg), use child/infant pads if available.
