CMAS Oxygen Provider

Course Overview & Training Objectives

The CMAS Oxygen Provider certification trains divers to recognize pathological symptoms of dysbarism, severe hypoxia, and near-drowning, and to administer emergency normobaric oxygen safely. The course details hyperbaric gas physiology, the biological mechanism of nitrogen off-gassing under pure O2, and potential physiological hazards. Students gain operational fluency in deploying demand valves for spontaneously breathing patients and constant-flow reservoir masks for non-breathing victims.
