Unit 5　First Aid Period1　Warming-up and Reading 眩暈是我們生活中經(jīng)常發(fā)生的事情，在其發(fā)生前，人們會(huì)有不同感覺(jué)；在其發(fā)生后，必須馬上進(jìn)行急救，以免造成更大傷害！ First aid for fainting Fainting is a brief loss of consciousness. Someone who faints may pass out for several seconds or up to an hour. There are many reasons why people faint. Medical reasons include: Low blood sugar. Any condition in which there is a rapid loss of blood. Heart attack. Heatstroke (中暑) or heat exhaustion. A sudden change in body position like standing up too quickly. Extreme pain. Sudden emotional stress or fright. Anxiety. Just before fainting, a person may: Feel a sense of dread (恐懼). Feel dizzy. Have nausea (反胃). Here are some dos and don’ts to remember if someone is about to faint or faints: Dos: Catch the person before he / she falls. Have the person lie down with the head below the level of the heart. Raise the legs 8 to 12 inches. This promotes blood flow to the brain. If a victim who is about to faint can lie down right away, he / she may not lose consciousness. Turn the victim’s head to the side. Loosen any tight clothing. Apply slightly wet towels to the person’s face and neck. Keep the victim warm, especially if the surroundings are very cold. Don’ts: Don’t slap (拍) or shake anyone who’s just fainted. Don’t try to give the person anything to eat or drink, not even water, until he / she is fully conscious. Don’t allow the person who’s fainted to get up until the sense of physical weakness passes. Then be watchful for a few minutes to be sure he / she doesn’t faint again. Fill in the blanks: 1.
