The incident report at http://www.mikey.net/aue/incidentreport.htm (thanks Xavier Merlin for posting the link) is well written and clearly reveals a clonic-tonic seizure by the victim. The differential diagnoses are now, in order of probability: 1) oxtox seizure, or 2) cerebral arterial gas embolism, or 3) primary seizure disorder. Syncope (fainting) from ascent or from postural hypotension should not produce a seizure. Xavier, you are correct in recognizing that the preferred rescue position is supine, with the legs not elevated, but it probably does not matter greatly. The victim is undoubtedly being evaluated by a neurologist for any seizure disorder, and the fact that he has already had a seizure would lead some physicians to advise against returning to diving. Furthermore, if CAGE is felt to be the final diagnosis, then pulmonary barotrauma has likely occurred, and again some physicians would advise against returning to diving. Sorry folks, but a seizure for any reason is felt by some docs to be an absolute contraindication to further diving. Gotta watch the O2 (keep the pO2's below MOD and watch the CNS O2 clock). Hopefully this diver only suffered an oxtox seizure, has a full recovery without residual problems, and maybe someday will be cleared to return to diving.
