Quick Answer
Use an AED before starting CPR. This is because the Automated External Defibrillator (AED) is specifically designed to analyze and correct life-threatening arrhythmias. By using the AED first, you can potentially restore a normal heartbeat and avoid unnecessary CPR.
Understanding the AED Process
When responding to a cardiac emergency, the American Heart Association (AHA) recommends following the chain of survival: call 911, perform CPR, use an AED if available, and continue CPR if the AED does not shock the heart. If you have access to an AED, use it as soon as possible, ideally before initiating CPR. This is because the AED can quickly analyze the heart’s rhythm and deliver an electric shock if needed, increasing the chances of successful resuscitation.
Using the AED Before CPR
When using an AED, follow these steps: (1) turn on the device and follow the voice prompts, (2) attach the electrode pads to the victim’s bare chest, (3) analyze the heart’s rhythm and wait for the device to determine if a shock is needed, (4) if a shock is required, the AED will deliver it, and (5) continue to follow the device’s prompts. After the AED has been used, begin CPR with chest compressions and rescue breaths. The AHA recommends 30 chest compressions followed by two breaths, at a rate of 100 to 120 compressions per minute.
Key Considerations
It is essential to remember that the AED is not a substitute for CPR but rather a complement to it. CPR should continue to be performed according to established guidelines, even if the AED is used. Additionally, always follow local protocols and guidelines for using defibrillators.
