According to The American Heritage Medical Dictionary, advanced life support (ALS) is defined as "emergency medical care for sustaining life, including defibrillation, airway management, and drugs and medications."
In Oklahoma, prehospital ALS providers include EMT-Intermediate (EMT-I), Advanced EMT (AEMT), and Paramedic. According to the 2014 Oklahoma State EMS Protocols, EMT-I and AEMT perform very similar interventions. The Paramedic Scope of Practice is the widest of all EMS providers.
