When Should the Rescuer Operating an AED Clear the Patient?
The question of when to clear the patient during AED use is crucial for successful resuscitation. It's not about clearing the patient in the sense of physically moving them, but rather ensuring everyone is clear of the patient before delivering the shock. This critical step prevents accidental injury and ensures the AED functions correctly.
The simple answer is: Always clear the patient before pressing the shock button on an AED. This applies to every shock delivered during the resuscitation process.
Here's a more detailed breakdown, addressing common questions:
What Does "Clear the Patient" Mean?
"Clear the patient" means ensuring absolutely no one is touching the patient while the AED is analyzing their heart rhythm and delivering a shock. This includes:
- The rescuer: Don't be in contact with the patient's chest or body.
- Bystanders: Everyone else in the vicinity needs to move away from the patient, including those offering assistance.
- Medical equipment: Ensure no medical equipment is touching the patient, as this can interfere with the AED's operation.
Why is Clearing the Patient So Important?
Accidental contact with the patient during a shock can lead to serious injury or even death for the person making contact. The electrical current needs to pass through the patient's heart to be effective; any alternative pathway can cause harm to someone else. Additionally, external contact can interfere with the AED's ability to accurately read the heart rhythm, potentially leading to an incorrect analysis or an inappropriate shock.
How to Effectively Clear the Patient Before Shocking:
-
Announce Clearly: Before pressing the shock button, shout "Clear!" or "Everyone clear!" loud and clearly to ensure everyone understands what's about to happen.
-
Verify: Visually check that everyone is clear of the patient before delivering the shock. Don't rely solely on hearing responses; actively look to confirm everyone is safe.
-
Maintain Distance: Maintain a safe distance (at least a few feet) from the patient throughout the AED process.
-
Repeat for Each Shock: Repeat steps 1-3 before each shock administered by the AED.
What Happens if Someone is Touching the Patient During a Shock?
If someone accidentally makes contact with the patient during a shock, the current can pass through that person, potentially causing burns, muscle contractions, or even cardiac arrest. The shock may also be less effective in treating the patient's arrhythmia.
How Often Should I Clear the Patient?
Every time the AED analyzes the heart rhythm and advises a shock, you MUST clear the patient before pressing the shock button. Clearing the patient is not just a one-time procedure; it's a critical step repeated throughout the entire defibrillation process.
By diligently following the procedure for clearing the patient before each shock, rescuers can minimize risks and improve the chances of successful resuscitation. Remember, the safety of both the patient and all those involved is paramount.
