The Montana coup

4、le who fought off a bear. The guy in Utah who cut off his arm to free himself from under a fallen rock. Youve probably read many stories like this and wondered how to keep yourself out of the dangers. Heres what to do in some life- threatening emergencies when no ones around to help. Allergic Reacti

5、on Bee stings, food allergies, and medications can be deadly, even if you think you dont have allergies. Symptoms include itching in one spot or all over your body, sometimes accompanied by a rash, swelling, and, in the extreme, swelling of the airways, which hampers your ability to breathe. If you

6、know you have a life-threatening allergy, form an action plan with your doctor, who will probably prescribe an EpiPen, which comes in child and adult doses. It delivers the drug epinephrine (肾上腺素 ), which keeps the heart pumping, improves breathing, and gives you about 20 minutes to get to a hospita

7、l. Even if you dont have severe allergies, you can still be prepared for a spontaneous reaction. Slip a few maximum-strength antihistamines (抗组胺剂 ), into your wallet. The fast-acting tablets will begin to fight an allergic reaction while you wait for help to arrive. But since antihistamines can make

8、 you drowsy, dont drive yourself to the ER (急诊室 ). Choking Richard Stennes, MD, was home alone in La Jolla Shores, California, eating a steak, when the phone rang. The 64-year-old swallowed down the bite still in his mouth and answered the call. But the steak was stuck, and he couldnt talk or breath

9、e. He put his finger down his throat to grab the meat, but he couldnt reach it. Gagging (使呕吐 ) didnt help either. So he walked over to the couch and forcefully thrust his abdomen on the hard arm of the couch, sending the meat flying and allowing him to breathe again. If youre ever in the same situat

10、ion, quickly find a chair or other piece of furniture or a kitchen counter, says Maurizio Miglietta, MD, chief of trauma at New York Presbyterian Hospital/Columbia University Medical Center. Aim to hit the top of the chair or edge of the counter against your upper abdomen, in the soft part below the

11、 bony upside-down V of the ribs. Thrust up and inward. If you still cant breathe after six tries, call 911 from a landline, even if you cant talk. Theyll find you. Write the word choking somewhere nearby, and leave the line open until help arrives. Heart Attack If youre experiencing crushing chest p

12、ain with or without pain in your left arm, are short of breath, or have a sense of impending doom, you may be having a heart attack. (Women are more likely to have atypical symptoms like severe fatigue, nausea, heartburn, and profuse sweating. ) Call 911 and chew one 325 mg uncoated aspirin, to get

13、it into your bloodstream fast. This will thin your blood, often stopping a heart attack in its tracks. While waiting, lie down so that your heart doesnt have to work as hard, says Sandra Schneider, MD, a spokeswoman for the American College of Emergency Physicians. If you think you might pass out, t

14、ry forcing yourself to cough deeply. It changes the pressure in your chest and can have the same effect as the thump given in CPR, says Dr. Schneider, “Sometimes it can jolt the heart into a normal rhythm.“ If someone else goes into cardiac arrest, note that the American Heart Association now recomm

15、ends CPR without the mouth-to-mouth: Call 911, then push hard and fast on the persons chest until help comes. Bear Attack If you surprise a bear, dont run away. That invites an attack. Instead, stand up and back away slowly, without looking the bear in the eyes. Speak softly to the animal (no loud s

16、houting). If it does charge at you, try to make yourself look as large as possible: Stick out your chest, raise your arms, and spread your legs. Now you can yell at the bear, to frighten it. If its going to attack, lie facedown, with your hands clasped behind your neck. Play dead and dont get up unt

17、il youre sure the bear is gone. Leave the area immediately in case it returns. If youre in bear country, carry a bear-deterrent pepper spray. Make sure the wind isnt blowing toward you, and spray for one to two seconds when the bear is 30 to 40 feet away. Severe Bleeding Youre bleeding severely and

18、getting scared. Forget about tourniquets (止血带 ), says Dr. Schneider of the American College of Emergency Physicians. Use your hand or a clean cloth, paper towels, a scarf, or any fabric you can grab, and push down on the wound until the bleeding stops. Tourniquets, which every Boy Scout learned how

19、to make back in the day, are now a first-aid no-no. “If you have a cut on your upper leg and you put pressure on it, youre just closing that vessel. But if you put a tourniquet on, youre going to close the vessels to the entire leg,“ says Dr. Schneider, “You could lose your foot.“ The only time to u

20、se a tourniquet, says Charles Pattavina, MD, chief of emergency medicine at St. Joseph Hospital in Bangor, Maine, is when you know that everything below the wound is beyond repair (say, the accident has severed your finger, arm, or leg). Rising Water Rule No. 1: Never drive through standing water. A

21、s thousands of stranded motorists can attest, what looks like a small puddle can be much deeper. “It takes just 12 inches of water to carry a car away,“ says Robert Sinclair, Jr., of AAA New York. If you do get stuck, step out of the car, which will likely stop when the water reaches the vehicles el

22、ectronic controls. If the water is higher than the bottom of your knees or is moving too quickly for you to wade (涉水 ) through, climb on top of your car and wait for help. Otherwise, get to higher ground. If you suddenly become immersed (say, you drive off a bridge or into a lake or river), roll dow

23、n the windows as soon as you can. Yes, it allows water to rush in, but thats a good thing, says Sinclair. It equalizes the pressure, so you can open the door or swim out the window. Do it quickly, though, as the electrical systems on automatic windows can get damaged and stop working when wet. A lif

24、e hammer can shatter automotive glass and cut through seat belts; Sinclair keeps one between the drivers seat and the center console in case of such emergencies. Break the side windows (windshields are usually thicker and harder to crack), and swim toward high, dry land. Trapped in a Burning Buildin

25、g If youre in an office building and cant get out, dont panic. “In any emergency situation, the difference between survivors and non-survivors is that survivors remain calm and fight through their fear to find out, What can I do?“ says Dr. Schneider. So think back to those fire-safety lessons you le

26、arned in grade school. Call 911. Close yourself in a smoke-free room and place a wet towel underneath the door to prevent any smoke from entering, says Dan McBride, a firefighter in New York City. Then get low to the ground, where you can breathe and see better, until help arrives. If youre in a hou

27、se, get as low as you can and crawl outside as fast as possible. Dont stop until youre well away from the fire.
