What is the most common cause of a blocked airway in an unconscious victim?

• A. Choking
• B. Allergic reaction
• C. Fluid in lungs
• D. Bite

Answer: (A)

When someone becomes unconscious, the muscles that normally keep the airway open relax, and the tongue can fall back and partially or completely block the airway. This immediate blockage is what first aid courses refer to as choking in an unconscious person, making it the most common cause of a blocked airway in that situation. While allergic swelling, fluid in the lungs, or bites can cause breathing problems, they’re less likely to create a complete airway obstruction right after loss of consciousness. The key idea is that loss of muscle tone lets soft tissues block the airway, so choking is the typical culprit. If you’re caring for an unconscious person, check for breathing and be prepared to clear the airway and provide resuscitation if needed.
