综合类C级：阅读理解First Aid
First aid is emergency care for a victim of sudden illness or injury until more skillful medical treatment is available. First aid may save a life or improve certain vital signs including pulse， temperature， an unobstructed airway， and breathing. In minor emergencies， first aid may prevent a victims condition from worsening and provide relief from pain. First aid must be administered as quickly as possible. In the case of the critically injured， a few minutes can make the difference between complete recovery and loss of life.
First-aid measures depend upon a victims needs and providers level of knowledge and skill. Knowing what not to do in an emergency is as important as knowing what to do. Improperly moving a person with a neck injury， for example， can lead to permanent spinal injury and paralysis.
Despite the variety of injuries possible， several principles of first aid apply to all emergencies. The first step is to call for professional medical help. The victim， if conscious， should be reassured that medical aid has been requested， and asked for permission to provide any first aid. Next， assess the scene， asking other people or the injured persons family or friends about details of the injury or illness， any care that may have already been given， and preexisting conditions such as diabetes or heart trouble. The victim should be checked for medical bracelet or card that describes special medical conditions. Unless the accident scene becomes unsafe or the victim may suffer further injury， do not move the victim.
First aid requires rapid assessment of victims to determine whether life-threatening conditions exist. One method for evaluating a victims condition is known by the acronym ABC， which stands for：
A- Airway： is it open and unobstructed?
B- Breathing： is the person breathing? Look， listen， and feel for breathing.
C- Circulation： is there a pulse? Is the person bleeding externally? Check skin color and temperature for additional indications of circulation problems.
Once obvious injuries have been evaluated， the injured persons head should be kept in a neutral position in line with the body. If no evidence exists to suggest potential skull or spinal injury， place the injured person in a comfortable position. Positioned on one side， a victim can vomit without choking or obstructing the airway.
