When a victim of any age group with a Foreign Body Airway Obstruction (FBAO) becomes unresponsive, what is the next step after the rescuer has sent someone to call 911?

If a victim with a Foreign Body Airway Obstruction becomes unresponsive, the rescuer should start Cardiopulmonary Resuscitation (CPR) and use an Automated External Defibrillator (AED) while waiting for emergency services.

Explanation:

When a victim of any age group with a Foreign Body Airway Obstruction (FBAO) becomes unresponsive, the next steps after having sent someone to call 911 include:

Lowering the individual to the ground, if they are not already lying down.
Beginning Cardiopulmonary Resuscitation (CPR) if the person is not breathing or only gasping, which might be the case if the obstruction is not completely cleared.
For a trained person, using an Automated External Defibrillator (AED) if available, as this can provide potentially life-saving defibrillation in the event of a cardiac arrest.

CPR should be administered as per the current guidelines with modifications that include performing chest compressions and checking the mouth for the obstruction before delivering rescue breaths. If an AED is on hand, the unit can provide vocal guidance during the resuscitation process.
