Have you ever wondered what happens if there's a medical emergency on a plane? Well, the flight attendants are given enough training to act as first responders! They can perform the Heimlich maneuver or administer CPR if needed. There are also first aid kits and any plane that carries over thirty passengers has defibrillators on board. Some aircrafts even have a facility called 'MedLink' where the flight crew can establish direct contact with a medical professional on the ground to gain advice.
Also, whenever there's an emergency, the cabin crew asks if there's a doctor on board. Research has shown that there are doctors onboard as many as 70% of all commercial flights, so the chances of someone being present are pretty high.
