First aid requires rapid assessment of victims to determine whether life-threatening conditions exist. One method for evaluating a victim#39;s 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 person#39;s 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.
It is very important in first aid to
A．move the injured person from the scene of accident immediately.
B．spend a few minutes for making the difference between recovery and death.
C．know what to do and what not to do according to the condition of the victim.
D．remove the medical bracelet or card from the victim.
