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   16  only once — for a woman who had merely fainted. But the   17  made me quite curious about how   18  this kind of thing happens. I wondered what I would do if   19  with a real midair medical emergency — without access   20  a hospital staff and the usual emergency equipment. So   21  the New England Journal of Medicine last week   22  a study about in-flight medical events, I read it   23  interest.

　　The study estimated that there are a(n)   24  of 30 in-flight medical emergencies on U.S. flights every day. Most of them are not   25 ; fainting and dizziness are the most frequent complaints.  26  13% of them — roughly four a day — are serious enough to   27  a pilot to change course. The most common of the serious emergencies   28  heart trouble, strokes, and difficulty breathing.

　　Let’s face it: plane rides are   29 . For starters, cabin pressures at high altitudes are set at roughly      30  they would be if you lived at 5,000 to 8,000 feet above sea level. Most people can tolerate these pressures pretty   31 , but passengers with heart disease   32  experience chest pains as a result of the reduced amount of oxygen flowing through their blood.   33  common in-flight problem is deep venous thrombosis — the so-called economy class syndrome (综合症).   34  happens, don’t panic. Things are getting better on the in-flight-emergency front. Thanks to more recent legislation (立法), flights with at      35  one attendant are starting to install emergency medical kits to treat heart attacks.
