Administering emergency oxygen is the preferred first aid for scuba diving injuries, and early administration can drastically improve the outcome for an injured diver. The DAN Emergency Oxygen for Scuba Diving Injuries course teaches divers how to administer life-saving oxygen first aid to divers who may be suffering from decompression illness (DCI). Additionally, this course will teach divers how to recognize the signs and symptoms of decompression illness and respond to them accordingly. The emergency response skills taught in this course are not unique to scuba diving; they’re applicable to many other watersports and other activities.  Teaching this course will enable others to save lives and reduce the impact of DCI.
