Understanding Defibrillators: When to Use and When Not to Use One

Defibrillators are crucial for saving lives in cases of sudden cardiac arrest, but they can be confusing to use, especially in situations where seizures are mistaken for cardiac emergencies. It's essential to know the correct scenarios for using a defibrillator, specifically if you're dealing with someone who's having a seizure.

Key Points to Remember When Deciding Whether to Use a Defibrillator

What Happens with Public Access Defibrillators (AEDs):

When it comes to Public Access Defibrillators (AEDs), it's crucial to understand what they do and what they don't do. AEDs are designed to treat specific heart rhythms that lead to sudden cardiac arrest. If a person is having a seizure, the defibrillator will not deliver a shock. AEDs will indicate 'no shock advised' and the device will not power up or deliver a shock. This is because seizures are a result of the brain misfiring, not a problem with the heart.

“If this is a Public Access Defibrillator… NOTHING. It will only defibrillate a very specific lethal heart rhythm…”

Red Cross Basic Life Saving Course:

These misconceptions can be dangerous. If you have access to an AED in a public space, it’s important to understand its limitations. If you accidentally trigger the device when it’s not necessary, you could cause harm. Therefore, it's advised to take a Red Cross Basic Life Saving Course to learn the correct procedures and understand the limitations of these devices.

“To prevent you from accidentally causing harm you should take a Red Cross Basic Life Saving Course.”

Clinical Defibrillators for Professionals:

While AEDs are designed for public use and will not deliver a shock, clinical defibrillators used by professionals can indeed deliver a shock to someone having a seizure. However, this would be incorrect and potentially harmful as the seizure is not a cardiac issue.

“Using a defibrillator that’s available to the general public an AED absolutely nothing will happen. It is programmed to shock only two heart dysrhythmias neither of which are present when someone is having a seizure. It will say ‘no shock advised’ and will not shock the patient.”

On the other hand, if you have a heart monitor such as those used in emergency medical services (EMS) or in hospital settings, you would be able to manually shock someone, but again, this should not be done during a seizure.

“But we wouldn’t shock someone having a seizure because their heart is not having issues— it’s a brain misfire. Doing so could create a serious dysrhythmia/cardiac issue.”

Conclusion:

Clearly understanding the differences between heart issues and neurological conditions like seizures is crucial when using defibrillators. In cases of seizure, the focus should not be on using a defibrillator but rather on providing support and assistance to prevent injury and ensure the person regains consciousness safely. If in doubt, always err on the side of caution and seek professional help immediately.

Key Takeaways

AEDs are specifically designed for cardiac emergencies and will not deliver a shock for non-cardiac issues such as seizures. Public and clinical defibrillators differ in their capabilities, with AEDs being more limited in their use. Accredited courses, such as those offered by the Red Cross, are essential for understanding appropriate use and care.
