As a physician who travels quite a lot, I spend a lot of time on planes listening to that dreaded “Is there a doctor on board?” announcement. I’ve been 71 only once—for a woman who had merely fainted. But the 72 made me quite curious about how 73 this kind of thing happens. I wondered what I would do if 74 with a real mid-air medical emergency—without access 75 a hospital staff and the usual emergency equipment.

The most common of the serious emergencies 83 heart trouble, strokes, and difficult breathing. 外語(yǔ)學(xué)習(xí)網(wǎng)
