In a situation where you are a lone BLS provider and the patient is unresponsive with occasional gasping, what should you do if there is no carotid pulse?

In a scenario where a lone BLS provider encounters an unresponsive patient with occasional gasping and there is no carotid pulse, the immediate action should be to recognize this as a critical situation indicating that the patient is experiencing cardiac arrest.

Starting CPR, particularly with chest compressions, is a foundational response in such emergencies. This action is crucial because continuous chest compressions help maintain blood flow to vital organs, significantly improving the chances of survival until advanced help can arrive.

Activating the AED as soon as possible is essential, as it will provide the necessary analysis of the heart rhythm and potentially deliver a shock if indicated. By powering on the AED and applying adult pads, the provider sets up to deliver appropriate care rapidly if the device identifies a shockable rhythm. This step works in conjunction with CPR, as the AED can be used as soon as it is available, allowing for immediate lifesaving actions.

Reassessing the patient's responsiveness and pulse can lead to unnecessary delays in care, and placing the patient in the recovery position is not suitable in this case, as it could compromise the airway and prevent effective CPR.

Therefore, powering on the AED and preparing for its use is the correct response aligned with BLS protocols in the face of suspected cardiac arrest
