4、 you 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.

5、pital. 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.

6、ake you drowsy, dont drive yourself to the ER (急诊室).ChokingRichard Stennes, MD, was home alone in La Jolla Shores, California, eating a steak, when the phone rang.

8、n, 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.

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, try f

12、orcing 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 recommends

13、CPR without the mouth-to-mouth: Call 911, then push hard and fast on the persons chest until help comes.Bear AttackIf 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 shouting

17、 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.

Do it quickly, though, as the electrical systems on automatic windows can get damaged and stop working when wet. A life hammer can shat

22、ter 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 BuildingIf youre in an of
