First aid refers to the immediate and basic medical help given to someone who has been injured or suddenly became ill. It involves simple techniques and procedures that can be performed with minimal equipment and training. The main goals of first aid are to protect life, prevent the condition from becoming worse, and help in recovery. Common first aid practices include evaluating the situation, applying bandages to wounds, performing CPR if needed, and providing comfort and emotional support to the person until professional medical help arrives. Learning basic first aid skills can be crucial in emergencies and everyday situations.
