　　Being a physician who flies mh often, a lot of my time is spent on planes listening for that fearful “Is there a doctor on board?” announcement. I’ve been 41 only once --- for a woman who had merely fainted(昏厥). But the 42 made me quite curious about how 43 this kind of thing happens. I wondered what I would do if 44 with a real mid-air medical emergency --- without access 45 a hospital staff and the usual emergency equipment. So 46 the New England Journal of Medicine last week 47 a study about in-flight medical events, I read it with 48.

　　The study estimated that there are a(n) 49 of thirty in-flight medical emergencies on U.S. flights every day. Most of them are not 50; fainting and dizziness are the most frequent complaints. 51 13% of them --- roughly four a day --- are serious enough to 52 a pilot to change course. The most common of the serious emergencies 53 heart trouble, strokes, and difficult breathing.

　　Let’s face it: plane rides are 54. For starters, cabin pressures at high altitudes are set at roughly 55 they would be if you lived at 5,000 to 8,000 feet above sea level. Most people can tolerate these pressures pretty 56, but passengers with heart disease 57 experience chest pains as a result of the reduced amount of oxygen flowing through their blood. 58 common in-flight problem is deep venous thrombosis(静脉血栓) --- the so-called economy class syndrome. 59 happens, don’t panic. Things are getting better on the in-flight-emergency front. Thanks to more recent laws, flights with at 60 one attendant are starting to install(安装) emergency medical equipment to treat heart attacks.
