What is the treatment for severe anaphylactic symptoms?

• A. Evacuate passengers
• B. Administer oral antihistamines
• C. Medical assistance/MedLink; O2; lay flat 8-12 in; blanket; check ID bracelet
• D. Sit upright and monitor

Answer: (C)

Severe anaphylaxis on board requires rapid medical involvement and stabilization to support breathing and circulation while professional help is obtained. The best on-board action is to call for medical assistance (MedLink) and provide supportive care: administer oxygen, place the passenger flat to help maintain blood pressure and perfusion, cover with a blanket to keep them warm, and check for a medical ID bracelet to quickly identify allergies or relevant history. This approach directly addresses the life-threatening nature of the reaction and coordinates expert guidance, which is crucial in the constrained in-flight environment.

Evacuating passengers isn’t the immediate therapeutic step and delays stabilization. Oral antihistamines don’t reverse airway swelling or shock and are far too slow for severe reactions. Sitting upright can worsen airway compromise and hypotension, whereas lying flat helps stabilize circulation.
