What happens when the dreaded “Is there a doctor on board?” call rings out at 35,000 feet? On this high-altitude episode, we’re joined by Dr. Ann Marshburn, pediatric hospitalist, former NASA researcher, and pilot, to explore the unique world of in-flight medical emergencies. We cover what you need to know before stepping forward, the equipment and resources available on planes, the medical conditions you’re most likely to encounter, and how to keep your cool when turbulence isn’t the only problem.
