Cardiac Arrest During Air Travel: An Important Citizen’s Role

Airports and planes should be relatively good locations for successful resuscitation, mainly due to the proximity of automated external defibrillators (AEDs) and responsive witnesses in the presence of cardiac arrest. It seems.

Researchers at the University of Washington School of Medicine reviewed 143 Cardiac arrest A case involving a traveler at Seattle-Tacoma International Airport from 2004 to 2019. Almost 40% of the 143 people survived the event. This is far higher than the 10% survival rate seen in all out-of-hospital cardiac arrests in the United States.

“I didn’t make a direct comparison in this white paper, but with the tools available, the life savings were four times higher. There’s still a long way to go in terms of 10% survival in other settings. It shows that. ” Dr. Thomas Rhea, a researcher and doctor at UW Medicine and King County, said.

The researchers wanted to understand the incidence, interventions, and consequences of cardiac arrest in the controlled environment of airports and planes, said Dr. Neil Chatterjee, a senior researcher at UW School of Medicine’s cardiologist.

“Our findings emphasize that traveler cardiac arrest can survive and early resuscitation intervention is important,” Chatterjee said. The treatise is today Journal of the American Heart Association..

The starting point for this study was based on the Federal Aviation Administration’s 2004 obligation to equip all commercial jets across the United States with AEDs. These portable machines can often be life-threatening if deployed shortly after cardiac arrest.

“AEDs help responders understand the fundamentals heart Rhythm at cardiac arrest. This is one of the important links in a series of behaviors that contribute to the survival of the patient. In our study, all survivors of in-flight arrests applied AEDs before EMS (Emergency Medical Services) and were shocked. ) Arrived. “

The 143 cardiac arrests were divided into two groups: on-plane (34) and off-plane (109) events.

Out-of-flight events were witnessed more often (89% to 74%) and more often “shockable” (72% vs. 50%) than in-flight events.

A shockable event is one in which the AED determines that the shock is potentially useful. But it’s also a function of the speed at which bystanders recognize cardiac arrest and apply an AED, Rea said.

“We chose the airport as the optimal setting,” he said. “Most of the arrests in this study were witnessed-this is the role of the citizens-and more than half of those events were presented in shocking rhythms, which meant a much better chance of resurrection. increase.”

Rapid recognition of cardiac arrest was more common onboard than onboard, and Chatterjee was found to be due to other leaflet assumptions that the victim was simply asleep.

“In the summary of the story of the incident on the plane, it was common to see phrases such as” the patient was most often seen at the end and was presumed to be asleep until the time of disembarkation, “” Chatterjee said. ..

Extrapolating their findings, researchers estimate 2,000 cardiac arrests each year around the world, involving travelers on airplanes, a quarter of which occur on airplanes.

“Recognizing the existence of arrests is the first step,” he added. “I don’t want to recommend waking up a sleeping flyer, but if you have an unresponsive neighbor or witness someone fall, it’s important to be aware of what’s going on. AED Look for and consider CPR. ”
