In a scenario where you are a lone BLS provider and find an unresponsive adult who is occasionally gasping with no carotid pulse, what should you do first?

In the scenario where you encounter an unresponsive adult who is gasping and has no carotid pulse, the priority is to initiate actions that will provide the best chance of survival. The correct action is to immediately begin CPR, starting with chest compressions.

When a person is unresponsive and in cardiac arrest, the lack of a pulse indicates that the heart is not effectively pumping blood, which can lead to irreversible brain damage and death if not addressed swiftly. Although gasping can sometimes be mistaken for breathing, it is not adequate to sustain life and should not delay resuscitation efforts.

Activating the AED (Automated External Defibrillator) is indeed crucial, but it should typically occur after starting CPR in such a scenario. The primary focus should always be on delivering effective chest compressions as quickly as possible since they help to circulate oxygenated blood to vital organs until advanced care can be provided. Time is critical in these situations, and immediate CPR is the foundation of effective BLS practices.
