An AED should be used when someone is unresponsive and not breathing properly.
Understanding AED Use
An Automated External Defibrillator (AED) is a life-saving device designed to deliver an electrical shock to the heart, helping to restore a normal heart rhythm during cardiac arrest. Knowing when to use an AED is crucial for timely intervention.
Key Indicators for AED Use
Based on the reference, an AED should be used when:
-
The person is unconscious (not responsive).
-
The person is not breathing properly. This includes the absence of normal breathing or abnormal breathing such as agonal gasps.
- Agonal Breathing: It is important to note that sometimes individuals experiencing a sudden cardiac arrest may exhibit agonal breathing for a short period (seconds to minutes) after their heart has stopped beating. This is not considered normal breathing.
Practical Steps for AED Application
- Confirm Unresponsiveness: Gently tap the person on the shoulder and shout, "Are you okay?" If there is no response, proceed to the next step.
- Check for Breathing: Look, listen, and feel for normal breathing for no more than 10 seconds. If there's no breathing or only agonal breathing, proceed to the next step.
- Retrieve the AED: Send someone to get the AED while you begin CPR.
- Turn On the AED: Once you have the AED, turn it on and follow the voice prompts. The AED will guide you through the process.
- Attach Electrodes: Expose the person's chest and attach the AED electrode pads as indicated on the pads themselves.
- Follow AED Instructions: The AED will analyze the person's heart rhythm and advise whether a shock is needed. Follow the instructions carefully.
- Continue CPR Continue CPR between any necessary shocks or until Emergency Medical Services (EMS) arrive.
Important Considerations
- Early Intervention: The sooner an AED is used, the better the chance of survival for someone in cardiac arrest.
- Safety: Ensure the area is clear before delivering an electrical shock from the AED to prevent injury.
- Training: Proper training on using an AED is crucial for effective and safe usage. Consider enrolling in a CPR/AED course.
Summary
In summary, use an AED when a person is unconscious and not breathing properly, this includes agonal breathing. Always follow the AED's voice prompts, and continue CPR when appropriate. The key to saving a life during cardiac arrest involves recognizing the symptoms, retrieving the AED, and taking action.
