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(綜合癥).
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.
