An estimated 40,000 plus in-flight medical events occur worldwide on commercial airlines each year. Holiday travelers can take steps to reduce the risk of a potential health problem occurring during flights.

If a medical event occurs, emergency evaluation and medical care are provided by a physician volunteer on the flight.

“Many in-flight medical events occur when a traveler has a serious medical condition that is aggravated by airline travel,” explained Dr. Raymond Bertino, clinical professor of radiology and surgery, University of Illinois College of Medicine. “If you have a serious illness, check with your doctor to be sure air travel does not pose an increased risk.”

Bertino is the lead developer of airRx, the only smartphone app to prepare and help physicians volunteering to assist fellow travelers experiencing a medical event on a flight. Physicians who volunteer to assist, can help travelers use the app to access 23 scenarios of the most common medical emergencies. The app provides concise treatment algorithms and quick reference information to help treat and evaluate the patient. AirRx provides a real-time checklist and handbook to improve the way emergent medical air situations are addressed. The app is provided by a non-profit organization and are available for full use in Airplane mode. Download the app at the Apple Store or Google Play store for $4.99

“Staying hydrated is essential, especially on long flights,” said Bertino. “I myself experienced a medical event while traveling because I neglected to follow that simple advice.”
