As a physician who travels quite a lot, I spend a lot of time on planes listening for that dreaded “Is there a doctor on board?” announcement. I’ve been  36 only once-for a woman who had merely fainted. But the   37 made me quite curious about how  38 this kind of thing happens. I wondered what I would do if  39 with a real mid-air medical emergency-without access  40 a hospital staff and the usual emergency equipment. So   41 the New England Journal of Medicine last week   42 a study about in-flight medical events, I   43 it with interest.
The study estimated that there are a(n)  44 of 30 in-flight medical emergencies on U.S. flights every day. Most of them are not   45 ; fainting and dizziness are the most frequent complaints.  46 13% of them-roughly four a day-are serious enough to   47 a pilot to change course. The most common of the serious emergencies   48 heart trouble, strokes, and  difficult breathing.
Let’s face it: plane rides are   49 . For starters, cabin pressures at high altitudes are set at roughly   50 they would be if you lived at 5,000 to 8,000 feet above sea level. Most people can tolerate these pressures pretty   51 , but passengers with heart disease   52 experience chest pains as a result of the reduced amount of oxygen flowing through their blood.  53 common in-flight problem is deep venous thrombosis（血栓）-the so-called economy class syndrome（综合症）.  54 happens, don’t panic. Things are getting better on the in-flight emergency front. Thanks to more recent legislation（立法）, flights with at   55 one attendant are starting to install emergency medical equipments to treat heart attacks.
