First aid is emergency care for a victim of sudden illness or injury until more skillful medical treatment is available. It may save a life. In many emergencies, first aid may prevent a victim’s condition from turning worse 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 a difference.
Firstaid measures depend upon the victim’s needs and the provider’s 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 (脊柱的) injury and paralysis (瘫痪)．
Despite the variety of injuries, several principles of first aid can 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 f or permission to provide any first aid. Next, assess the scene, asking people around or the injured person’s family or friends about details o f the injury or illness, any care that may have already been given, and preexisting conditions such as diabetes (糖尿病) or heart trouble. The victim should be checked for a medical 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 lifethreatening conditions exist. One method for evaluating a victim’s condition is known as the acronym (首字母缩略词) ABC, which stands for：
A—Airway: Is it open and clear?
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.
