低溫傷病員:體溫過低的注意事項

低溫傷病員:體溫過低的注意事項

It's really, crazy, unbelievably cold outside. So why read another story about how chilly you feel? Why not learn a thing or two about the worst-case scenario that can happen when it's frigid -- hypothermia.

外面真是太冷了。那么，為什么要讀另一個關于你有多冷的故事呢?為什么不了解一下在寒冷的天氣里可能發(fā)生的最壞的情況——體溫過低呢?

How many people die of hypothermia?

有多少人死于體溫過低?

The U.S. Centers for Disease Control and Prevention reports that, on average, at least 1,000 people die each year from the condition that strikes when a person's core temperature dips below 95 degrees Fahrenheit.

美國疾病控制與預防中心報告稱，平均每年至少有1,000人死于當人體核心溫度降至95華氏度以下時出現(xiàn)的疾病。

The stages of hypothermia begin when the body is losing heat faster than it can produce it. The condition typically affects people who abuse alcohol or drugs, elderly and very young people and the generally unhealthy, the National Institutes of Health says. Even babies who sleep in cold rooms can develop hypothermia, the CDC says.

當身體失去熱量的速度超過產(chǎn)生熱量的速度時，體溫過低的階段就開始了。美國國立衛(wèi)生研究院表示，酗酒或吸毒的人、老年人和非常年輕的人以及通常不健康的人通常會患上這種疾病。美國疾病控制與預防中心表示，即使是睡在寒冷的房間里的嬰兒也會發(fā)生體溫過低。

How do I know if hypothermia has set in?

我如何知道體溫過低?

Whether it's caused by exposure to cold weather or immersion in cold water, someone with hypothermia first begins to shiver to move muscles and generate heat, experts say. When the body stops shivering, that's a sign of significant trouble.

專家說，無論是暴露于寒冷的天氣還是浸泡在冷水中，體溫過低的人首先會顫抖，活動肌肉并產(chǎn)生熱量。當身體停止顫抖時，這是嚴重問題的跡象。

When hypothermia begins, the body's core functions work harder, pulling blood into extremities. Shivering is the body's involuntary survival instinct to jump-start muscles to maintain warmth.

當體溫過低開始時，身體將血液輸送到四肢的核心功能會更加困難。顫抖是身體不自覺的生存本能，是為了啟動肌肉來保持體溫。

If you start to shiver, shake it out.

如果你開始發(fā)抖，抖動吧。

"You should try to run, jump, move around. ... You should do anything you can to increase your body heat," said Jesse Schomberg, who works to educate Minnesotans about hypothermia at the Minnesota Sea Grant.

“你應該試著跑步，跳躍，四處走動……你應該盡你所能增加你的體溫，”明尼蘇達海洋基金會的杰西·熊伯格說。

It was zero degrees at 10 a.m. Wednesday in Minneapolis. Cold contributed to the deaths of 26 people in Minnesota between January and March 2014, the Minneapolis Star-Tribune reported.

周三上午10點，明尼阿波利斯的氣溫為零度。據(jù)《明尼阿波利斯星論壇報》報道，2014年1月至3月間，寒冷導致明尼蘇達州26人死亡。

Mild hypothermia can make a person dizzy, hungry, nauseous and make it harder to speak clearly. Motor skills will start to fail and a person may feel tired.

輕微的體溫過低會使人頭暈、饑餓、惡心，而且說話也很難清楚。運動技能會開始下降，人會感到疲勞。

Children typically develop bright red, cold skin. Babies' crying will grow weak. On the rare occasion that someone survives hypothermia, they describe being in a state of extreme confusion.

兒童的典型癥狀是皮膚變紅、變冷。嬰兒的哭聲會變?nèi)?。在極少數(shù)情況下，體溫過低的人幸存下來，他們描述自己處于極度混亂的狀態(tài)。

If there are few survivors, and they were confused, how do we know so much?

如果幸存者很少，而且他們很困惑，我們怎么知道這么多?

Gordon Giesbrecht and his assistants have artificially lowered his body temperature to the point of hypothermia at least 30 times, he said.

戈登·吉斯布雷希特和他的助手們已經(jīng)人工將他的體溫降低了至少30次，他說。

The associate dean of kinesiology and recreation management at University of Manitoba in Canada studies the effects of extreme weather and physical exertion on the body.

加拿大馬尼托巴大學運動機能學和娛樂管理副院長研究極端天氣和體力活動對身體的影響。

"When we took people into the woods, they always wanted to know about hypothermia and frostbite," Giesbrecht told CNN.

“當我們把人們帶到森林里的時候，他們總是想知道什么是低溫和凍傷，”吉斯布雷希特告訴CNN。

For a long time, medical experts believed that it would hurt a hypothermia victim to warm them right away, that might it might cause cardiac arrest or some other shock to the system, he said.

他說，很長一段時間以來，醫(yī)學專家一直認為，立即給體溫過低的患者保暖會對他們造成傷害，可能會導致心臟驟停或其他一些系統(tǒng)休克。

Giesbrecht's experiments have also given hope to the survival odds for someone who falls into cold water and develops hypothermia.

吉斯布雷希特的實驗也給那些掉進冷水并體溫過低的人帶來了生存的希望。
