Is There a Doctor on Board?: In-Flight Sudden Cardiac Arrest and Automated External Defibrillator Use

Area of Science:

• Aviation Medicine
• Emergency Medical Services
• Public Health

Background:

• In-flight sudden cardiac arrest (IFCA) is a rare but highly fatal event on commercial flights, causing up to 86% of in-flight casualties.
• Key risk factors include male sex, advanced age, pre-existing cardiac conditions, and prolonged flight duration.
• Prompt intervention with cardiopulmonary resuscitation and automated external defibrillators (AEDs) is crucial for survival.

Purpose of the Study:

• To highlight the challenges and propose solutions for managing IFCA in the unique airline environment.
• To emphasize the importance of AEDs and standardized training for improving patient outcomes.
• To advocate for legislative and procedural changes to enhance in-flight cardiac arrest response.

Main Methods:

• Review of existing research on IFCA risk factors, outcomes, and current response protocols.
• Analysis of challenges posed by the confined airline environment on emergency response.
• Examination of the role of technology like telemedicine and legal frameworks like Good Samaritan laws.

Main Results:

• AED use dramatically increases survival rates from approximately 6% to 21-70%.
• Significant challenges exist in aircraft, including limited space, delayed equipment access, and extended diversion times.
• Lack of mandated AED legislation and standardized CPR training represents a critical gap in care.

Conclusions:

• Universal AED placement on commercial flights is recommended.
• Standardized airline-specific CPR and AED training, telemedicine integration, and clear legal protections are essential.
• These measures can significantly improve passenger survival rates from IFCA.
