Can an automatic external defibrillator be used by someone who is not a trained medical professional?

An automatic external defibrillator (AED) is designed to be used by individuals with varying levels of training, and it often comes with visual and auditory prompts to guide users through the process of administering a shock. AEDs are particularly user-friendly, making them accessible for use in emergency situations.

In many emergency response scenarios, bystanders who may not be specifically trained medical professionals can effectively use AEDs as long as they follow the device's instructions. The emphasis on training and familiarity is important, but it's worth noting that even laypeople with minimal instruction can often use an AED correctly during emergencies.

In this case, while the option refers to trained medical professionals, it limits the AED's accessibility and utility. The critical aspect to remember is that the implementation of AEDs is encouraged among bystanders to save lives during cardiac emergencies, regardless of their formal medical training. Thus, the correct stance is that an AED can and should be used in emergencies by anyone willing to assist.
