EMS has evolved significantly since the Good Samaritan provided first aid in 1500 BC. The Flying Ambulance designed in 1797 helped treat soldiers on the battlefield. Baron Larrey is considered the father of triage and modern EMS, designing medical supply kits and ambulances. The first official ambulance services began in the US in the 1860s-1870s. Advancements like CPR in the 1960s improved pre-hospital care. Today, paramedics can perform many advanced life-saving procedures in the field like intubation, chest tubes, and medications that were once only done in hospitals. EMS now brings emergency medical care directly to the patient.
