To properly prepare a chest for defibrillation, ensure a clear and dry surface for effective pad placement and electrical conduction.
Here's a step-by-step guide:
-
Expose the Chest: Remove all clothing from the patient's chest. This includes shirts, bras, and any other obstructive materials. Time is of the essence in a cardiac arrest situation.
-
Dry the Chest: If the chest is wet (due to sweat, water, or other fluids), quickly wipe it dry with a towel or cloth. Moisture can interfere with the defibrillator's ability to deliver the electrical shock effectively.
-
Remove Excessive Hair (If Necessary): Excessive chest hair can prevent good contact between the defibrillator pads and the skin. If necessary, quickly shave the areas where the pads will be placed. Many AEDs contain a small razor for this purpose. Consider using a towel to sweep away the loose hair.
-
Defibrillator Pad Placement: Correct pad placement is crucial for effective defibrillation.
-
Standard Placement (Adults):
- Pad 1: Upper right chest, below the collarbone.
- Pad 2: Lower left chest, below the armpit.
-
Alternative Placement (if necessary, e.g., pacemaker or ICD): Anterior-Posterior placement can be used if the standard placement is obstructed. Place one pad on the front of the chest and the other on the back, between the shoulder blades. Ensure pads don't touch each other.
-
-
Ensure Contact: Once placed, firmly press the pads onto the skin to ensure full contact. Good contact maximizes the chances of delivering an effective shock.
Key Considerations:
- Pacemakers/ICDs: Avoid placing defibrillator pads directly over implanted pacemakers or implantable cardioverter-defibrillators (ICDs). Place the pads at least one inch away from the device.
- Jewelry: Remove any jewelry or metal objects from the chest area, as these can interfere with the electrical current.
- Medication Patches: Remove any medication patches (e.g., nitroglycerin patches) from the chest before applying the defibrillator pads. These patches can cause burns or interfere with the electrical current.
- Oxygen: If possible, move any oxygen source away from the patient during defibrillation to minimize the risk of fire.
By following these steps, you can properly prepare the chest for defibrillation, increasing the chances of a successful outcome.
