Commercial in-flight medical emergencies
From WikEM
Contents
Background
- Incidence of in-flight emergencies: 1 per 604 flights[1] (0.3% of cases died)
- For reference, there are ~29,000 commercial flights per day in the US alone[2]
- As the population ages and people travel longer distances, this number is likely to increase[3]
Epidemiology[1]
- Syncope or presyncope (37.4%)
- Respiratory symptoms (12.1%)
- Nausea or vomiting (9.5%)
- Cardiac symptoms (7.7%)
- Seizures (5.8%)
- Abdominal pain (4.1%)
- Infectious disease (2.8%)
- Agitation or psychiatric symptoms (2.4%)
- Allergic reaction (2.2%)
- Possible stroke (2.0%)
- Trauma, not otherwise specified (1.8%)
- Diabetic complication (1.6%)
- Headache (1.0%)
- Arm or leg pain or injury (1.0%)
- Obstetrical or gynecologic symptoms(0.5%)
- Ear pain (0.4%)
- Cardiac arrest (0.3%)
- Laceration (0.3%)
Emergency Medical Kit
- The FAA requires all aircraft with >30 passengers to carry an Emergency Medical Kit and an AED[4]
- This requirement is the "minimum acceptable", but some airlines carry more extensive kits

Management
General Approach
- Flight crew is responsible for responding to medical emergencies in flight - your role is to offer assistance, not to take control[6]
- Identify yourself and level of medical training to the crew
- Ask a flight attendant to obtain the emergency medical kit (EMK)
Patient Assessment
- Identify chief complaint and perform HPI and appropriate focused physical exam
- Obtain vital signs - emergency medical kit will have sphygomomanometer
- Measuring BP by palpation may be easier than auscultation in flight
- If the patient is unresponsive or in cardiac arrest, obtain and apply an automated external defibrillator (AED)
Management Options
- Goal is to keep patient stable until the flight lands[6]
- Management should be based on your assessment and evidence-based best practices, but within the confines of the resources available on board
- e.g. angina/chest pain may be given aspirin (± NTG), hypoglycemic episodes may be given PO or IV dextrose, vasovagal syncope may be given PO fluids or placed in leg-elevated position, etc.
- Be aware of available options
- Emergency medical kit, oxygen, and AED
- May ask crew to lower altitude of plane (increases cabin pressure)[6]
- May request to speak with ground-based physician consult service
- May request diversion of flight to closer airport (ultimate decision rests with captain)
Medicolegal Issues
- Responding to a request for assistance creates a "doctor-patient" relationship[7]
- Duty to respond[4]
- There is no legal duty for a physician to respond to an in-flight emergency in the USA, Canada, and the UK (in the absence of a pre-existing doctor-patient relationship)
- In Australia and many European countries, there is a legal duty to respond
- Legal jurisdiction is usually determined by the country in which the aircraft is registered, but the location of the incident may apply as well[7]
United States
- The Aviation Medical Assistance Act (AMAA) of 1998 provides liability coverage for "medically qualified individuals" who provide medical care aboard an aircraft and imposes a standard of "gross negligence or willful misconduct"
- Covers a wide range of medically trained passengers, including physicians, nurses, PAs, paramedics, EMTs, etc.
- Provider is not prohibited from accepting compensation in order to receive liability protection under the AMAA[7]
"An individual shall not be liable for damages in any action brought in a Federal or State court arising out of the acts or omissions of the individual in providing or attempting to provide assistance in the case of an in-flight medical emergency unless the individual, while rendering such assistance, is guilty of gross negligence or willful misconduct."—Aviation Medical Assistance Act of 1998, Public Law 105–170—April. 24, 1998.pdf
