Primeros Auxilios Básicos is a free Android app developed by Proyecto-TIC.es that serves as a guide and reminder for trained volunteers in basic first aid and life support techniques. The app covers a wide range of emergency situations including constant vitals, RCP, OVACE, shock, hemorragias, and many more. It also includes a basic first aid kit, the PAS behavior, and what first aid means. The app is designed to be used as a reference guide and not to replace formal training or professional medical advice. It is strongly recommended for volunteers of rescue groups, the Red Cross, and any first responder who has received formal training in first aid and basic life support.
