The primary purpose of first aid treatment is to provide initial care to a sick or injured person until professional medical help arrives. The goals of first aid are to:

• Preserve Life: To prevent immediate death by addressing critical issues such as airway obstruction, lack of breathing, or severe bleeding.
• Prevent Further Harm: To protect the person from additional injury or complications, such as moving them from a dangerous situation or stabilizing a fracture.
• Promote Recovery: To offer comfort, support, and basic care that can aid in the healing process and prevent the condition from worsening.

First aid can involve a wide range of interventions, from cleaning and bandaging a small wound to performing CPR on someone who has stopped breathing. The specific actions taken depend on the nature and severity of the injury or illness.
