Medical Emergencies Happen

Medical emergencies can happen any time — even mid-flight! Luckily, flight attendants and the rest of the crew are trained accordingly to handle a series of situations that may be thrown their way.Flight attendants are trained to act as first responders in the event that there is a medical emergency during a flight. This includes things like CPR and the Heimlich maneuver. All planes are also equipped with defibrillators and first aid kits if a passenger may need care during a flight.

If there is a more grave situation, the flight attendants might ask if there is a doctor on board. A pilot may also choose to divert and ground the plane, which usually takes just 15 or so minutes, unless it is an overseas flight.
