Primary Care Paramedics (PCP) are the entry-level of paramedic practice in Canadian provinces. The scope of practice includes performing semi-automated external defibrillation, interpretation of 4-lead ECGs, administration of Symptom Relief Medications for a variety of emergency medical conditions (these include oxygen, epinephrine, dextrose, glucagon, salbutamol, ASA and nitroglycerine), performing trauma immobilization (including cervical immobilization), and other fundamental basic medical care. Primary Care Paramedics may also receive additional training in order to perform certain skills that are normally in the scope of practice of Advanced Care Paramedics. This is regulated both provincially (by statute) and locally (by the medical director), and ordinarily entails an aspect of medical oversight by a specific body or group of physicians. This is often referred to as Medical Control, or a role played by a base hospital. For example, in the provinces of Ontario and Newfoundland and Labrador, many paramedic services allow Primary Care Paramedics to perform 12-lead ECG interpretation, or initiate intravenous therapy to deliver a few additional medications.
