Step-by-Step Guide to Operating an AED | Wellbeing

1. Power On & System Check

• Open the AED lid.

• Turn on the power switch.

• (Note: Ensure the victim's chest is dry, the pad placement area is free of excessive hair, and remove any metal jewelry or devices from the victim.)

2. Attach Electrode Pads

• Peel the backing off the electrode pads.

• Attach the pads to the victim's chest following the AED's voice prompts:

  • Place the first pad on the upper right chest, directly below the collarbone.

  • Place the second pad on the lower left side (below the armpit), as shown on the pad diagram.

• (Note: Pad placement positions differ for small children compared to adults.)

3. Heart Rhythm Analysis

• The AED will automatically begin analyzing the victim's heart rhythm.

• This process takes a few seconds.

• The device will announce the analysis result via voice and visual prompts.

• (Crucial Note: During the analysis phase, the rescuer and bystanders must NOT TOUCH the victim.)

4. Deliver Shock (If Necessary)

• If a shockable rhythm (fibrillation) is detected, the AED will instruct the user to deliver a shock.

• Ensure no one is touching the victim while the shock is being prepared.

• Press the Shock button (usually flashing) as instructed by the AED.

• The AED will deliver an electrical pulse to stop the fibrillation, allowing the heart to re-establish an effective rhythm.

5. CPR Guidance and Monitoring

• Immediately after the shock (or if "No Shock Advised"), the AED will instruct the user to perform CPR (Cardiopulmonary Resuscitation) until medical help arrives.

• The device may provide a metronome to count chest compressions and guide breathing to ensure CPR is performed effectively.

• Some advanced AED models provide real-time feedback to ensure the rescuer is performing compressions at the correct depth and rate.

6. Power Off

• Once the victim shows signs of recovery or when emergency medical personnel arrive and take over, the AED can be turned off. Data recorded during the rescue can be saved/exported for medical review.

⚠️ Important Safety Notes:

• Read the user manual carefully before use (if possible).

• Do not use the AED if the victim is submerged in water or lying on conductive metal surfaces.

• Call Emergency Services (115) immediately after assessing the victim's condition if any abnormalities are detected.
