The respiratory system is made up of organs involved in the gas exchange of oxygen and carbon dioxide. As a paramedic, you will look after many people experiencing a compromised respiratory system. You will have to assess and treat these patients quickly and correctly. If you have ever had the wind knocked out of you, you can appreciate the panic that these patients feel. As you work through your PCP program, you will have to understand how these structures work and how they can fail. You will also be inserting various pieces of plastic into these structures. The first section details the anatomy of the respiratory system and includes many high return facts. The second section provides an overview of the topics that you must understand to graduate as a Primary care Paramedic. These topics have been selected by the Paramedic Association of Canada (PAC) as required knowledge. The Canadian Organization of Paramedic Regulators (COPR) will use these same topics to write the exam that you must pass to be licensed in Canada.
