Arterial Gas Embolism
Diagnosis of Arterial Gas Embolism
Based on diving history and loss of consciousness Divers who lose consciousness during ascent or very shortly afterward are assumed to have arterial gas embolism. They must be treated promptly. Imaging tests are sometimes done but are not always reliable. Any diver who loses consciousness shortly after surfacing should be assumed to have arterial gas embolism and should be treated with hyperbaric oxygen as quickly as possible.
