The Star of Life is a symbol used to identify emergency medical services. It features a blue six-pointed star, outlined by a white border. The middle contains a Rod of Asclepius – an ancient symbol of medicine. The Star of Life can be found on ambulances, medical personnel uniforms, and other objects associated with emergency medicine or first aid. Elevators marked with the symbol indicate the lift is large enough to hold a stretcher. Medical bracelets sometimes use the symbol to indicate one has a medical condition that emergency services should be aware of.

Emergency medical services (EMS), also known as ambulance services or paramedic services, are emergency services that provide urgent pre-hospital treatment and stabilisation for serious illness and injuries and transport to definitive care. They may also be known as a first aid squad, FAST squad, emergency squad, ambulance squad, ambulance corps, life squad or by other initialisms such as EMAS or EMARS.
