First aid is the initial assistance given to someone who is injured or suddenly ill. It involves assessing the situation, protecting the victim from further harm, and treating them for shock while waiting for emergency medical help to arrive. The key aims of first aid are to preserve life, prevent the condition from worsening, and promote recovery. It is important to act quickly but remain calm, check if the victim is breathing, ensure their comfort, and never give them food or drink without medical approval. Basic first aid supplies include bandages, antiseptic, scissors, and other materials for treating wounds and providing initial care.
