Course Synopsis

The Emergency Diving Accident Management (EDAM) course is designed to produce more thoroughly educated and competent participants who will leave the course with a deeper understand of the causes, effects, recognition, treatment, and prevention of diving accidents from the planning of dives to the hyperbaric treatment of diving casualties.

Demonstration on the water.If you are a physician, work in emergency medical services; teach, lead, or work in recreational or commercial diving; are interested in volunteering with the Catalina Chamber Crew; or are just an interested diver, the EDAM course at the Catalina Hyperbaric Chamber will provide you with information that all divers, and people who manage diving accidents need to know.

Learn about diving accidents that have occurred and what type of events, equipment, or errors lead to the problem. Get an in-depth look at how decompression tables and dive computers are put together and what Doppler bubble detection has to do with current decompression research. Understand the problems and research associated with flying after diving.

Grasp the physiology and pathology of decompression sickness and air embolism injuries. Discover about the effects of nitrogen narcosis and oxygen toxicity and how they play a major role in technical diving operations.

Practice neurological assessments of a diving casualty and understand the importance of oxygen administration, information gathering and efficient communication and coordination with local rescue agencies. Find out what is done with an accident victim upon arrival at a hyperbaric chamber and how hyperbaric treatments are performed and benefit divers.
