First-aid measures are immediate actions taken to help someone who is injured or suddenly ill. These measures can include assessing the situation, calling for help, and providing basic care such as applying pressure to a wound, performing CPR, or using an automated external defibrillator (AED) if necessary. The goal is to stabilize the person's condition until professional medical assistance arrives. It is important to have a basic understanding of first-aid techniques, as they can save lives in emergencies. Knowing how to treat common injuries, such as burns, cuts, or sprains, can make a significant difference. First-aid training courses are available to teach these essential skills.
