You spin around and see the little girl clutching her hand, her tears streaming from her eyes, the telltale pot of hot water spilled on the ground. Do you know what to do?Step Pre-readingT: Today we ar

83、 then answer the questions about their own various experiences. After a few minutes.T: Now stop talking. We are going to get the answers from the text. Lets read the text and try to find the answers.Step While-readingT: The passage is a text from a book called First Aid for the Family. It is a quick
84、-reference book which is organized under headings in such a way that readers can quickly find the information they want. In this type of text, it is common for information to be in note form. It is also common that ellipsis is used in giving instructions. The article the is often omitted in the inst
85、ructions under First aid treatment, for example, cover burnt area instead of cover the burnt area; hold bandage in place instead of hold the bandage in place. While reading you should pay more attention to this kind of ellipsis. SkimmingAsk the Ss to read the title of the text and the headings withi

94、 a hospital at once.T: Very good. Most good readers survey texts in this way before they start to read the text in detail. If you survey a text, it makes it easier to understand it because you already know something about the content and the organization. Now read Ex. 2. You dont have to read the wh
95、ole text to find the information you need to answer this question. Which part of the text do you need to look at? S: The section under the heading Characteristics of burns.

96、 with them. And then do Ex. 4.T: After reading, lets answer some questions. You may discuss in groups for 5 minutes, then we will check the answers.1. Why should you put cold water on a burn?The cold water stops the burning process, stops the pain and prevents or reduces swelling. 2. Why doesnt a th
97、ird degree burn hurt?Because the nerves have been damaged. If there are no nerves, there is no pain.3. Why do you think clothes and jewellery near burns should be removed?Because this may break any blisters and the wound may get infected. / Bacteria from the clothes and jewellery could infect the bu

101、is trying to tell us first aid is important. People who have witnessed an accident often wish that they had done things differently. Seconds count in an emergency, and knowing what to do can mean the difference between life and death. The most important thing to keep in mind when dealing with an eme
102、rgency is to stay calm. If we were to panic, we could not be able to help. By staying calm we will be able to think what to do and make better decisions. We can also prepare for an emergency by learning more about first aid. Calling an ambulance or the police is important, but there is more we can a
103、nd should do. If we know how to respond, we can save lives. This passage does not contain enough information for you to do first aid correctly! You have to study with a teacher. However, after a few hours of study you will manage to know enough to save other peoples lives. So much for today. Here I

Lets learn “Learning about Language”.First lets do Discovering useful words and expressions. Complete the table with the correct verbs,
108、 nouns or adjectives. You are to explain the words on the screen in English and then fill in the blanks.Ask students to explain or guess the meanings of the words.injury, poisonous, burn, swollen, damage, treatment, wounded, infect injury n. physical damage done to a person or a part of their body a

Complete the questions with words from the text. The students will try to complete the exercises. Later the
113、teacher will ask some of them to read each of the sentences and tell the class the answers.Step GrammarT: Lets look at the next, Grammar Present some sentences and encourage the students to find out which words have been left out.T: Observe the following sentences and discuss with your partner to fi
114、nd out what have been left out. Let me show you an example. As we know, when people want the speaker to repeat what he said, they usually say “Beg your pardon.” Then it is called Ellipsis. The subject “I” has been left out, without changing the meaning of the sentence. OK, now its your turn to find
115、out what have been left out.1. Thank you.2. Some more tea?3. Sounds like a good idea.4. Doesnt matter.5. Sorry to hear that.6. Pity you couldnt come7. This way, please.8. Terrible weather!9. Joining us for a drink? 10. Going to the supermarket?11. Dr. Robertson?12. Any news?Suggested answers:1. I th
116、ank you.2. Would you like some more tea?3. That / It sounds like a good idea.4. It doesnt matter.5. Im sorry to hear that.6. Its / What pity you couldnt come.7. Step this way, please.8. What terrible weather it is!9. Are you joining us for a drink? 10. Are you going to the supermarket?11. Are you Dr
117、. Robertson?12. Is there any news?T: About the omission:1.In a familiar speech, the subject is sometimes left out when it is a pronoun;2.Sometimes even more than the subject may be dropped at the beginning of a sentence if the meaning is clear; Though the preparatory there is not a subject, it behav
118、es like one and is often omitted;3.To avoid repetition, a verb is frequently left out when the same verb has appeared in an earlier part of the sentence: Then winter came and with it (came) the snow.4.Omission of the auxiliary or the principal part of the verb compound is very frequent: Summer had c
119、ome and (had) gone. Can you do that? Yes, I can (do it).5.The verb do/does/did frequently stands for another verb which has appeared earlier. This is a very important use of this auxiliary, which comes in very handy at times. As there is no counterpart of it in Chinese, it should be thoroughly maste
120、red through constant practice. Eg. Do you go there every day? Yes, I do (= go there every day). Did you see her? Yes, I did ( = saw her).Shall I read it? Please do (= read it).I like Beijing very much, as everybody does (= likes it) who has been there.Step PractisingDiscovering useful structures (pa
121、ge 37)1. In groups, look at these pairs of sentences. Discuss the difference between A and B in each pair. Also discuss which is the better sentence, A or B and Why. 2. Rewrite these sentences taking out the unnecessary parts.3. These sentences are correct. However, one or more words have been left

130、knowledge of first aid can save lives. Let the Ss discuss the following scenario (=situation) in groups.T: Now boys and girls, imagine you can hear someone screaming. You find him sitting on the ground, bleeding heavily from deep knife wounds in his hands. What would you do? Will you help him? Will
131、you call the police and ambulance, or whether you perform first aid? After a few minutes, the discussion is over.T: Today we are going to learn a story Heroic Teen-ager Receives Award. Skim the newspaper article and put the events in the correct order in Ex. 1.Five minutes later, check the answers.T
132、: Good. From the answer, we know the main idea of the news. Often we readers only want to get a quick idea of a newspaper article and do not want to know all the details. For this reason they might read just the headline and the first paragraph. This is because the headline gives readers a clue abou
133、t the content and the first paragraph gives the most important information. So we should pay attention to the first paragraph. It may give us a lot of information that answers the five “W” Questions: Who? What? When? Where? Why? And also How?Let the Ss read the headline of the newspaper article on p
134、 38.T: What do you think the story is about by reading this headline?S: From the headline, we can guess that the story is about a young man who sets us a good example because he could save ones life using his knowledge of first aid. Ask students to read the first paragraph and write the following qu
135、estion words on the Bb.T: Now, read the headline and the first paragraph to see if you can find the answer to the 5 W Questions. Who? What? When? Where? Why? Ss: Yes, I can find: Who? John Janson; What? was honoured at the Lifesaver Awards; When? last night;Where? in Rivertown; Why? for carrying out
136、 lifesaving first aid on his neighbour after a shocking knife attack.T: Right. So we should pay more attention to the head-line and the first paragraph.Step While readingAsk the Ss to read the news from beginning to end. And then listen to the tape and answer the questions.1. What did John do when h
137、e heard the screaming?He was studying in his room.2. What happened to Anne?She had been stabbed repeatedly with a knife. She was lying in her front garden bleeding very heavily. Her hands had almost been cut off.3. What saved Ms Slades life?It was Johns quick action and knowledge of the first aid th
138、at saved her life.4. What first aid did John perform on Anne?John dressed Ms Slades in juries with tea towels and applied pressure to the wounds to slow the bleeding.5. What adjectives would you use to describe Johns actions? Give at least three.Brave, heroic, courageous, quick-thinking, quick-minde
139、d, helpful, fearless, unselfish, confident Step DiscussionDivide the class into groups to discuss the issues in Ex. 4. Make the discussions more lively by encouraging the Ss to think of different scenarios such as:1. Do you think John was silly or brave to get involved in the situation? Give reasons
140、.2. Would you have done the same as John? Give reasons.3. Do you think it is worthwhile to take a course in first aid? Give reasons.4. What if the attacker had still been at the scene of the stabbing?5. What if the attacker had gone but had then returned to the woman?6. What if the woman had AIDS?7.
141、 What if John had performed first aid on the woman but she died anyway? How would he feel about having tried to help her?Show the above on the screen. T: Now lets discuss the above questions. The students discuss for 5 minutes in groups and then share their ideas. Encourage the students to express t
142、heir ideas. Have each group appoint a spokesperson to present their views to the class. Different answers are welcome.For example:Sa: John was silly: he could have been attacked also, it was none of his business, the woman might have had AIDS.Sb: He was brave: he could have been attacked too, but he
143、 didnt think about his own safty. All he thought about was how to help the victim.Sc: The Chinese saying Saveing one life is better than building up a 7-floor tower. I think anyone who is in that situation should help her.T: From the discussion, we can draw a conclusion that learning first aid knowl
144、edge is very important. You can use it to help others, even save ones life. So try to do first aid before the doctor comes.Step TaskShow the following passages on the screen. Let the Ss read them and then talk about how to do first aid for drowning.Most children enjoy playing in water in hot summer.
145、 Its messy and noisy and fun. Water can also be dangerous. Its hard to remember that something so enjoyable can also be deadly. Take the time to protect your children from the dangers of water a playful friend that can steal their lives in mere minutes. More than 1,000 American youngsters drown each
146、 year. Neighborhood swimming poolsAbout 300 children under the age of 5 drown each year in U.S. swimming pools. At the time of the incidents, most victims were being supervised by one or both parents. Nearly 70 percent of the children were not expected to be near the pool when they were found in the
147、 water.It takes only a few minutes for a child to drown. More than three-quarters of children who drown at neighborhood pools are missing from sight for less than five minutes. Drowning is also a silent death. There is no splashing to alert anyone that the child is in trouble.The key to preventing t
148、hese tragedies is to have multiple levels of protection. The following precautions can help keep children safer around swimming pools:Fence it in. Pools should be completely surrounded by fencing material at least 4 feet tall. Chain link works well. A slatted fence should have no gaps wider than 4 i
149、nches, so kids cant squeeze through. Gates should be self-closing and self-latching. The latch should be out of a childs reach. Install alarms. If your house is one of the walls of your pool enclosure, doors leading to the pool area should be protected with alarms. In addition, add an underwater poo
150、l alarm that sounds when something hits the water. Make sure you can hear the alarm inside the house. Cover it up. A motor-powered safety cover can provide a barrier over the water when the pool is not in use. The cover should withstand the weight of two adults and a child in case a rescue is needed
151、. Choose an above-ground pool. Above-ground pools are much safer than in-ground pools, because the height of the pool serves as a barrier. However, you should remove the steps or lock them behind a fence when the pool is not being used. Teach children to swim. But remember that swimming lessons wont
152、 drown-proof your child. The age to teach children to swim is the same as to ride a bike, age 5. Children under the age of 4 usually arent developmentally ready for formal instructions in swimming. Remove toys. Dont leave pool toys bobbing in the water when no one is using the pool. Children may try
153、 to retrieve a toy and fall in. Keep your eyes peeled. Never leave a child un-supervised near a pool. During social gatherings near pools, adults can take turns being the “designated watcher.” Natural bodies of waterSwimming conditions are unpredictable in lakes, rivers and oceans. The depth can cha
154、nge rapidly, as can water temperature, currents and the weather. Murky water may conceal hazards. Follow these tips to be safer:Dont swim alone. Teach children never to swim alone or without adult supervision. Wear a life jacket. Children should be required to wear a personal flotation device whenev
155、er riding in a boat or fishing, even along a river bank. Air-filled swimming aids, such as water wings, are no substitute for a life jacket. Jump before you dive. The first rapid descent into any body of water should be a jump feet first. Diving into unknown water can result in a smashed skull or a
156、broken neck. Avoid alcohol. Accidents increase with the amount of alcohol consumed. Teenage boys are at highest risk. Beware of thin ice. Drownings can occur in the winter, too. Avoid walking, skating or riding on weak or thawing ice on any body of water. Look at the two pictures on the screen. Imag
157、ine that you are at the scene. What should you do? What first aid will you perform on the drowning? A possible answer:Your first priority is to get a drowning child out of the water as soon as possible. If she isnt breathing, place her on her back on a firm surface. Immediately begin rescue breathin
158、g, below, and have someone call for help. Dont assume its too late to save a childs life even if shes unresponsive, continue performing CPR and do not stop until medical professionals take over.1. To open your childs airway gently tilt her head back with one hand, and lift her chin with the other. P
159、ut your ear to the childs mouth and nose, and look, listen, and feel for signs that she is breathing.2. If your child doesnt seem to be breathingInfants under age 1: Place your mouth over infants nose and lips and give two breaths, each lasting about 1/2 seconds. Look for the chest to rise and fall.
160、Children 1 and older: Pinch childs nose and seal your lips over her mouth. Give two slow, full breaths (1/2 to 2 seconds each). Wait for the chest to rise and fall before giving the second breath. 3. If the chest rises, check for a pulse (see number 4). If the chest doesnt rise, try again. Retilt th
161、e head, lift the childs chin, and repeat the breaths.4. Check for a pulse Put two fingers on your childs neck to the side of the Adams apple (for infants, feel inside the arm between the elbow and shoulder). Wait five seconds. If there is a pulse, give one breath every three seconds. Check for a pul
162、se every minute, and continue rescue breathing until the child is breathing on her own or help arrives.5. If you cant find a pulse Infants under age 1: Imagine a line between the childs nipples, and place two fingers just below its center point. Apply five half-inch chest compressions in about three
163、 seconds. After five compressions, seal your lips over your childs mouth and nose and give one breath. Children 1 and older: Use the heel of your hand (both hands for a teenager or adult) to apply five quick one-inch chest compressions to the middle of the breastbone (just above where the ribs come
164、together) in about three seconds. After five compressions, pinch your childs nose, seal your lips over his mouth, and give one full breath.All ages: Continue the cycle of five chest compressions followed by a breath for one minute, then check for a pulse. Repeat cycle until you find a pulse or help

Do you know what such a letter would include?S: The letter should: say we have done a unit on first aid say why the unit was useful explain the importance of doing a first aid course say what we would like the principal to doAsk th
178、e Ss to write the letter individually. Circulate and help the Ss with grammatical structures and written expression.Sample answers:Dear Mr Chen,Our class has been studying a unit on first aid. We have realized first aid is very helpful and very necessary, because it can be used whenever or wherever
179、we are in emergency. Even though the unit has been very interesting and useful, the ways it provides us are just too limited to certain situation. We can not protect us in any other dangerous situations. So we want to learn more about first aid. We would like to request that you could offer us a fir
180、st aid course a week. We think that a first aid course at the school can also teach us more about different kinds of first aid. In future we can stay calm and prepare for an emergency. If we know how to respond, we can save lives. Yours sincerely, Shirley Dear Mr Wang,Our class has been studying a u
181、nit on first aid. It tells us some basic knowledge of first aid. Therefore, when something emergent happens, we will not be at a loss.Even though the unit has been very interesting and useful, it only contains some safety measures at home. The information is limited. We are eager to know more about
182、first aid from other aspects.We would like to request that our school can provide us a first aid course. We think a first aid course at the school is quite important and necessary. In this way, we can learn how to protect ourselves and help others in the future. Yours sincerely, Ashley 附 件1. Animal
183、bitesDomestic pets cause most animal bites. Dogs are more likely to bite than cats. Cat bites, however, are more likely to cause infection. If an animal bites you or your child, follow these guidelines:For minor wounds. If the bite barely breaks the skin, treat it as a minor wound. Wash the wound th
184、oroughly with soap and water. Apply an antibiotic cream to prevent infection and cover the bite with a clean bandage. For deep wounds. If the bite creates a deep puncture of the skin or the skin is badly torn and bleeding, apply pressure to stop the bleeding and see your doctor. For infection. If yo
185、u notice signs of infection such as swelling, redness, increased pain or oozing, see your doctor immediately. For suspected rabies. If you suspect the bite was caused by an animal that might carry rabies any bite from a wild or domestic animal of unknown immunization status see your doctor immediate
186、ly.2. SnakebitesMost snakes arent poisonous. A few exceptions include the rattlesnake, coral snake, water moccasin and copperhead. Most poisonous snakes have slit-like eyes. Their heads are triangular, with a depression or pit midway between the eyes and nostrils.Other characteristics unique to cert
187、ain poisonous snakes:Rattlesnakes make a rattling sound by shaking the rings at the end of their tails. Water moccasins have a white, cottony lining in their mouths. Coral snakes have red, yellow and black rings along the length of their bodies. To reduce your risk of snakebites, avoid picking up or
188、 playing with any snake unless youre properly trained. Most snakes usually avoid people if possible and bite only when threatened or surprised.If youre bitten by a snake: Remain calm. Dont try to capture the snake. Immobilize the bitten arm or leg and try to stay as quiet as possible. Remove jewelry
189、, as swelling tends to progress rapidly. Dont cut the wound or attempt to remove the venom. Dont use a tourniquet or apply ice. Seek medical attention as soon as possible, especially if the bitten area changes color, begins to swell or is painful. 3. ChokingIn adults, choking is often the result of
190、inadequately chewed food becoming lodged in the throat or windpipe. Solid foods such as meat are frequently the cause.These factors increase the risk of choking: Talking while simultaneously chewing a piece of meat. Drinking alcohol while eating. Wearing dentures. Because dentures exert less chewing
191、 pressure than natural teeth and they interfere with the way food feels in the mouth, they make it more difficult to thoroughly chew food. Young children tend to put into their mouths almost anything that fits, so choking can occur unassociated with a meal.Panic accompanies choking. The choking vict
192、ims face often assumes an expression of fear or terror. At first the victim may turn purple, the eyes may bulge, and he or she may wheeze or gasp.If the person can cough freely, has normal skin color and can speak, he or she is not choking. If the cough is more like a gasp and the person is turning
193、blue, he or she is probably choking. If in doubt, ask the choking person if he or she can talk. If the person can speak, then the windpipe is not completely blocked and oxygen is reaching the lungs. If choking is occurring, begin to perform the Heimlich maneuver.To perform the Heimlich maneuver on s
194、omeone else:Stand behind the choking person and wrap your arms around his or her waist. Bend the person slightly forward. Make a fist with one hand and place it slightly above the persons navel. Grasp your fist with the other hand and press hard into the abdomen with a quick, upward thrust. Repeat t
195、his procedure until the object is expelled from the airway. To perform the Heimlich maneuver on yourself:Position your own fist slightly above your navel. Grasp your fist with your other hand and bend over a hard surface a countertop or chair will do. Shove your fist inward and upward. Clearing the
196、airway of a pregnant woman or obese person:Position your hands a little bit higher than with a normal Heimlich maneuver, at the base of the breastbone, just above the joining of the lowest ribs. Proceed as with the Heimlich maneuver, pressing hard into the chest, with a quick thrust. Repeat until th
197、e food or other blockage is dislodged or the person becomes unconscious. Clearing the airway of an unconscious person:Position the person on his or her back, look inside the mouth and sweep the area with your finger to see if you can remove the blockage. If not, kneel over the person and apply upwar
198、d thrusts to the upper abdomen. Repeat the process as necessary. Look inside the mouth again and sweep the area with your finger to try to remove the blockage. Then kneel over the person and apply upward thrusts to the upper abdomen. Clearing the airway of a choking infant:Assume a seated position a
199、nd hold the infant facedown on your forearm, which is resting on your thigh. Thump the infant gently but firmly five times on the middle of the back using the heel of your hand. The combination of gravity and the back blows should release the blocking object. If this doesnt work, hold the infant fac
200、eup on your forearm with the head lower than the trunk. Using two fingers placed at the center of the infants breastbone, give five quick chest compressions. If breathing doesnt resume, repeat the back blows and chest thrusts. Call for emergency medical help. If one of these techniques opens the air
201、way but the infant doesnt resume breathing, begin mouth-to-mouth resuscitation. The universal sign for choking is a hand clutched to the throat, with thumb and fingers extended. If a person displays this sign, dial 911 or call for emergency medical assistance. Dont leave the person unattended.4. Cut
202、s and scrapesMinor cuts and scrapes usually dont require a trip to the emergency room. Yet proper care is essential to avoid infection or other complications. These guidelines can help you care for simple wounds:Stop the bleeding. Minor cuts and scrapes usually stop bleeding on their own. If they do
203、nt, apply gentle pressure with a clean cloth or bandage. Hold the pressure continuously for 20 to 30 minutes. Dont keep checking to see if the bleeding has stopped because this may damage the fresh clot thats forming and cause bleeding to resume. If the blood spurts or continues to flow after contin
204、uous pressure, seek medical assistance. Clean the wound. Rinse out the wound with clear water. Soap can irritate the wound, so try to keep it out of the actual wound. If dirt or debris remains in the wound after washing, use tweezers cleaned with alcohol to remove the particles. If debris remains em
205、bedded in the wound after cleaning, see your doctor. Thorough wound cleaning reduces the risk of tetanus. To clean the area around the wound, use soap and a washcloth. Theres no need to use hydrogen peroxide, iodine or an iodine-containing cleanser. These substances irritate living cells. If you cho
206、ose to use them, dont apply them directly on the wound. Apply an antibiotic. After you clean the wound, apply a thin layer of an antibiotic cream or ointment such as Neosporin or Polysporin to help keep the surface moist. The products dont make the wound heal faster, but they can discourage infectio
207、n and allow your bodys healing process to close the wound more efficiently. Certain ingredients in some ointments can cause a mild rash in some people. If a rash appears, stop using the ointment. Cover the wound. Exposure to air speeds healing, but bandages can help keep the wound clean and keep har

If youre allergic to the adhesive used in most bandages, switch to adhesive-free dressings or sterile gauze held in place with paper tape, gauze roll or a loosely applied elastic bandage.
209、These supplies generally are available at pharmacies. Get stitches for deep wounds. A wound that cuts deeply through the skin or is gaping or jagged-edged and has fat or muscle protruding may require stitches. A strip or two of surgical tape may hold a minor cut together, but if you cant easily clos
210、e the mouth of the wound, see your doctor. Proper closure minimizes scarring and infection. Watch for signs of infection. See your doctor if the wound isnt healing or you notice any redness, drainage, warmth or swelling. Get a tetanus shot. Doctors recommend you get a tetanus shot every 10 years. If
211、 your wound is deep or dirty and your last shot was more than five years ago, your doctor may recommend a tetanus shot booster. Get the booster within 48 hours of the injury.5.

The value of 98.6 F (37 C) listed as normal body temperature is only a general guide. Isolated temperature elevations usually arent dangerous in an adult until the temperature reaches 103 F
213、 (39.4 C). Taking aspirin or acetaminophen (Tylenol, others) usually reduces a fever in adults. Dont give aspirin to children younger than 17 years of age. The use of aspirin has been linked with Reyes syndrome a rare but serious illness that can affect the blood, liver and brain of children and tee
214、nagers after a viral infection. How to take a temperatureYou can choose from several types of thermometers. Today, most have digital readouts. Some take the temperature quickly from the ear canal and can be especially useful for young children and older adults. Others can be used rectally, orally or
215、 under the arm. If you use a digital thermometer, be sure to read the instructions, so you know what the beeps mean and when to read the thermometer. Under normal circumstances, temperatures tend to be highest around 4 p.m. and lowest around 4 a.m.Due to the potential for mercury exposure or ingesti
216、on, glass mercury thermometers are being phased out.Rectally (for infants)To take your childs temperature rectally: Place a dab of petroleum jelly or other lubricant on the bulb. Lay your child on his or her stomach. Carefully insert the bulb one-half inch to one inch into the rectum. Hold the bulb
217、and child still for three minutes.To avoid injury, dont let go of the thermometer while its inside your baby. Remove and read the temperature as recommended by the manufacturer. A rectal temperature reading is generally 1 degree F higher than an oral reading. OrallyTo take your temperature orally: P

Heart attack
222、: First aidA heart attack occurs when one or more arteries supplying your heart with blood and oxygen become blocked. This loss of blood flow injures your heart muscle. A heart attack generally causes chest pain for longer than 15 minutes, but it can also be silent and have no symptoms at all.About
223、half the people who suffer a heart attack have warning symptoms hours, days or weeks in advance. The earliest predictor of an attack may be recurrent chest pain thats triggered by exertion and relieved by rest.The American Heart Association lists these warning signs and symptoms of a heart attack. B
224、e aware that you may not have all of them and that symptoms may come and go. Uncomfortable pressure, fullness or squeezing pain in the center of your chest, lasting more than a few minutes Pain spreading to your shoulders, neck or arms Lightheadedness, fainting, sweating, nausea or shortness of brea
225、th If you suspect a heart attack, even if it feels like indigestion, act immediately:1. Call 911 or emergency medical assistance. The operator contacts the emergency medical services (EMS) system. In areas without 911 service, call the emergency medical response system. Its usually better to call th
226、ese emergency numbers first. Calling your doctor may add unnecessary time. When you call, describe symptoms such as severe shortness of breath or chest pain. This ensures a priority dispatch of EMS responders (paramedics) trained in basic and advanced cardiac life support. Most EMS units carry a por
227、table defibrillator, a device that restores normal heart rhythm by delivering electrical shocks. Defibrillators can be critical to early successful treatment and survival. Many police and fire rescue units also carry defibrillators and may respond before an ambulance does. 2. Begin cardiopulmonary r
228、esuscitation (CPR). If the person youre calling about is unconscious, an emergency dispatcher may advise you to begin emergency treatment. If youre not trained in emergency procedures, doctors recommend skipping mouth-to-mouth rescue breathing and proceeding directly to chest compression. The reason
229、 is that if youre distracted by trying to perform unfamiliar breathing techniques, valuable lifesaving minutes might be lost for the person who needs help. The most important thing you can do is to proceed directly to chest compression to move blood to vital organs, particularly the brain and heart.
230、 If youre trained in emergency procedures, its important to do both mouth-to-mouth rescue breathing and chest compression. 3. Decide on the fastest method of transportation. A dispatcher automatically notifies the closest well-equipped EMS unit. Ideally, EMS responders should reach you within 4 to 5
231、 minutes. If you live in a rural or large metropolitan area, however, you may get to the hospital faster by having someone drive you. Dont drive yourself! 4. Go to the nearest emergency cardiac care facility. Identify in advance the nearest center staffed 24 hours a day with doctors trained to provi
232、de emergency cardiac care. 5. Chew aspirin. Aspirin inhibits blood clotting, which helps maintain blood flow through a narrowed artery. If you think youre having a heart attack, take one regular-strength aspirin and chew it to speed absorption. Avoid aspirin if you are allergic to it or if you have
233、bleeding problems. Dont delay calling for emergency help just because youve taken aspirin. Aspirin alone wont treat your heart attack. 7. Severe bleedingTo stop severe bleeding:1. Have the injured person lie down. If possible, position the persons head slightly lower than the trunk or elevate the le
234、gs. This position reduces the risk of fainting by increasing blood flow to the brain. If also possible, elevate the site of bleeding. 2. Remove any obvious dirt or debris from the wound. Dont remove any large or more deeply embedded objects. Dont probe the wound or attempt to clean it at this point.
235、 Your principal concern is to stop the bleeding. 3. Apply pressure directly on the wound. Use a sterile bandage, clean cloth or even a piece of clothing. If nothing else is available, use your hand. 4. Maintain pressure until the bleeding stops. When it does, bind the wound tightly with a bandage (o
236、r even a piece of clean clothing) and adhesive tape. 5. Dont reposition displaced organs. If the wound is abdominal and organs have been displaced, dont try to reposition them. Cover the wound with a dressing. 6. Dont remove the gauze or bandage. If the bleeding continues and seeps through the gauze
237、 or other material you are holding on the wound, dont remove it. Instead, add more absorbent material on top of it. 7. Squeeze a main artery if necessary. If the bleeding doesnt stop with direct pressure, apply pressure to the artery delivering blood to the area of the wound. Pressure points of the
238、arm are on the inside of the arm just above the elbow and just below the armpit. Pressure points of the leg are just behind the knee and in the groin. Squeeze the main artery in these areas against the bone. Keep your fingers flat. With your other hand, continue to exert pressure on the wound itself
239、. 8. Immobilize the injured body part once the bleeding has stopped. Leave the bandages in place and get the injured person to the emergency room as soon as possible.8. ToothacheTooth decay is the primary cause of toothaches for most children and adults. Bacteria that live in your mouth thrive on th
240、e sugars and starches in the food you eat. These bacteria form a sticky plaque that clings to the surface of your teeth.Acids produced by the bacteria in plaque can eat through the hard, white coating on the outside of your teeth (enamel), creating a cavity. The first sign of decay may be a sensatio

A toothache often indicates that your dentist will need to work on your teeth.Until you can see your dentist, try these self-care tips: Use dental floss to remove any food particles wedged between your teeth. Try sucking on an ice cube p
242、laced in the area of irritation. Sometimes ice may not help, though, and may even make pain worse. Take an over-the-counter (OTC) pain reliever to dull the ache. Apply an OTC antiseptic containing benzocaine directly to the irritated tooth and gum to temporarily relieve pain. Direct application of o
243、il of cloves (eugenol) also may help. Dont place aspirin or other painkiller directly against your gums as it may burn your gum tissue.Swelling, pain when you bite, a foul-tasting discharge and redness indicate infection. See your dentist as soon as possible.Call your dentist if: The pain persists f
244、or more than a day or two You have fever with the toothache You have trouble breathing or swallowing 9. NosebleedsNosebleeds are common. Most often they are a nuisance and not a true medical problem. But they can be both. Why do they start, and how can they be stopped?Among children and young adults
245、, nosebleeds usually begin on the septum, just inside the nose. The septum separates your nasal chambers.In middle aged and older adults, nosebleeds can begin on the septum, but they may also begin deeper in the noses interior. This latter form of nosebleed is much less common. It may be caused by h
246、ardened arteries or high blood pressure. These nosebleeds begin spontaneously and are often difficult to stop. They require a specialists help.To take care of a nosebleed: Sit upright. By remaining upright, you reduce blood pressure in the veins of your nose. This discourages further bleeding. Pinch
247、 your nose. Use your thumb and index finger and breathe through your mouth. Continue the pinch for 5 or 10 minutes. This maneuver sends pressure to the bleeding point on the nasal septum and often stops the flow of blood. To prevent re-bleeding after bleeding has stopped, dont pick or blow your nose
248、 and dont bend down until several hours after the bleeding episode. Keep your head higher than the level of your heart. If re-bleeding occurs, sniff in forcefully to clear your nose of blood clots, spray both sides of your nose with a decongestant nasal spray containing oxymetazoline (Afrin, Dristan
249、, others). Pinch your nose again in the technique described above and call your doctor.Seek medical care immediately if: The bleeding lasts for more than 15 to 30 minutes You feel weak or faint, which can result from the blood loss The bleeding is rapid or if the amount of blood loss is great Bleedi
250、ng begins by trickling down the back of your throatIf you experience frequent nosebleeds, make an appointment with your doctor. You may need to have the blood vessel thats causing your problem cauterized. Cautery is a technique in which the blood vessel is burned with electric current, silver nitrat
251、e or a laser. Sometimes, your doctor may pack your nose with special gauze or an inflatable latex balloon to put pressure on the blood vessel and stop the bleeding.10. Special ProblemsWhen part of the body has been torn off. Try to find the part Wrap it in a clean dressing and place in a plasctic ba
252、g. Put the bag on ice, but dont freeze. Take the part to the hospital. When an object is impaled in a wound. Do not remove it. You could reveal an open artery which would then be awfully hard to deal with, a.k.a. nearly impossible. Bandage many dressings around the object to immobilize it and suppor
253、t it in its position in the wound. Splinters. A small splinter in the skin should be removed with tweezers. For a splinter in the eye, seek emergency help immediately, do not touch it. Nosebleeds. Have the victim sit with his or her head tilted a little bit foward while pinching his or her nostrils
254、together. One could also place an ice pack on the bridge of the nose. Injury to the mouth. If the injury does not involve the head, neck, or spine, have the victim sit with the head slightly tilted foward. If the victim is unable to reach this position, place the victim on his or her side. This ensu
255、res that blood drains from the mouth. If the injury has broken the lip, place a cleanrolled dressing between the lip and gum. Applying cold can also help. If a tooth is knocked out . Place a small roll of sterile gauze in the gap left by the tooth that was knocked out. Pick up the tooth not by the r
256、oot, but by the crown, the part you see when you smile in the mirror. If you can, place the tooth back how it belongs in the socket. If you cant put the tooth back in, put the tooth in a container with cool, fresh milk. If this cannot be done, use water. Caring for a Minor Open Wound Stop the bleedi
257、ng by applying pressure with a clean, absorbant cloth, or if cloth is unavailalble, your fingers. If the blood soaks through, apply a second bandage on top. Do not take off the first bandage because it will disturb the clotting that has already taken place. If bleeding still doesnt stop, raise the w
258、ound above heart level. Once bleeding stops, clean the wound gently with soap and water, or just water. It is very important to get all debris or dirt out. Apply an antibiotic ointment such as bacitration or a triple antibiotic ointment. Remember, some people are allergic to these ointments, so cont
259、act your doctor if you have any doubts. Wrap the wound firmly in a cloth or a bandage. Do not cut off circulation! Covering the wound with a clean dressing, press against it firmly with your hand. Elevate the wound above the level of the heart. The clean dressing should then be covered over with a r
260、oll bandage (like an Ace) to hold the dressings in place. If bleeding still does not stop, add additional dressings over the roll bandage. Squeeze a pressure point, the artery against the bone. This is in the bottom upper arm, or where the leg bends at the hip. Once the bandages and pressure point a
261、re being maintained, have someone call EMS if they have not already. Types of Wounds Name DescriptionavulsionIn an avulsion, a portion of skin is torn.
