Advanced Life Support (ALS) is the level of pre-hospital medical care provided by advanced emergency medical technicians, and which is reserved for patients with serious illnesses or injuries. ALS includes procedures such as starting intravenous lines and administering medications, passing breathing tubes to ventilate non-breathing patients, utilizing heart monitors and defibrillators to name a few. ALS providers not only provide care on 911 type calls, but also on patient transfers from one hospital to another. Paramedic training is approximately one to one and a half years in length, and one must first be an EMT.
