First aid is the initial assistance given to a person who has been injured or who is in sudden physical distress. It is typically provided by a bystander or layperson, rather than by trained medical personnel. First aid can be administered for a wide range of conditions, from minor injuries and illnesses to life-threatening emergencies.
The main goal of first aid is to preserve life, prevent further injury or illness, and promote recovery. First aid is generally performed in three steps: assessment, intervention, and re-evaluation. In assessment, the first aider assesses the situation and decides what kind of care is needed. Intervention is the second step, in which the first aider provides care based on the assessment. Re-evaluation is the third and final step, in which the first aider reassesses the situation and, if necessary, intervenes again.
First aid is a valuable skill that everyone should know. It can mean the difference between life and death in an emergency situation.
