What should be the first response to a medical emergency onboard?

In a medical emergency onboard, the first response should be to call for assistance from qualified crew. This action ensures that those with specialized training and experience can quickly assess the situation and determine the best course of action. Crew members who are designated for medical emergencies often undergo specific training to handle various medical situations effectively and can utilize onboard medical equipment as needed.

This immediate response also helps in coordinating further actions, such as notifying medical personnel on the ground for when the aircraft lands. Their capability to evaluate the urgency of the situation ensures that the affected passenger receives appropriate care as quickly as possible.

Continuing with regular service could delay necessary medical attention and may worsen the individual's condition. Immediately landing the aircraft is not always the appropriate response unless the situation warrants it after professional assessment. Providing no response until instructed distracts from the urgency of the medical emergency, which could lead to negative outcomes for the patient. Therefore, calling for assistance from qualified crew is the most responsible and effective initial action in dealing with a medical emergency onboard.
