Analyze the clinical scenario

The question asks which steps are modified when a single rescuer treats an unresponsive, apneic adult patient. This scenario falls under the standard AHA Guidelines for Basic Life Support (BLS).

Evaluate the options

• Option 1: CPR is done at a different compression to ventilation ratio.

For adult CPR, the compression-to-ventilation ratio remains \(30:2\) regardless of whether there is 1 rescuer or 2 rescuers. Thus, this step is not modified.

• Option 2: Compressions can be omitted and just use ventilations.

If an adult is unresponsive and apneic (and has no pulse or only gasping), full CPR (compressions and ventilations) is required. Compressions cannot be omitted.

• Option 3: The rescuer should summon an AED and activate EMS.

When a single rescuer encounters an unresponsive adult, they must first activate the emergency response system (EMS) and retrieve an AED before starting CPR (unless the collapse was asphyxial/drowning-related, where they give 2 minutes of CPR first). This sequence is a critical modification of the immediate action plan for a lone rescuer to ensure help is on the way.

• Option 4: Single rescuers do not attempt BVM ventilations.

While bag-valve-mask (BVM) ventilation is difficult for a single rescuer, it is not a universally modified protocol step in the same way as the immediate activation of EMS and retrieval of an AED.

Confirm the correct protocol

Under AHA Guidelines, the immediate priority for a lone rescuer of an unresponsive adult is to activate EMS and get the AED.
