What should the lone BLS Provider do first upon recognizing a possible adult cardiac arrest?

In a situation where a lone BLS Provider suspects an adult cardiac arrest, the first step involves ensuring that life-saving measures can be implemented as quickly as possible. Powering on the AED (Automated External Defibrillator) and applying the pads is essential because the AED is a critical tool for evaluating the patient’s heart rhythm and administering a shock if necessary. This early intervention can significantly increase the chances of survival, as it prepares the responder to act immediately once EMS arrives.

The AED can provide audio and visual prompts to assist in assessing the situation further and guide the responder in next steps after the initial rhythm check. While chest compressions and calling for additional assistance are vital components of the resuscitation process, activating the AED and positioning it for immediate use takes precedence, as it ensures that the provider is ready to deliver a shock if indicated, which is crucial for restoring a normal heart rhythm in an arrested individual.
