First aid measures are immediate actions taken to help someone who is injured or ill before professional medical help arrives. These measures can include assessing the situation, calling for emergency services, and providing basic care such as CPR, controlling bleeding, or treating burns. Knowing how to perform these actions can save lives and reduce the severity of injuries. It is important to stay calm and ensure your own safety before assisting others. Basic first aid training can equip individuals with the skills needed to respond effectively in emergencies, making it easier to help those in need, whether it's a child, adult, or elderly person.
