This report highlights the possibility of neurological insult, eg, stroke, due to cerebral arterial gas embolism as a consequence of decompression stress after deep breath-hold dives. Thus, stroke as a clinical presentation of cerebral arterial gas embolism should be considered another risk of extreme breath-hold diving.
After rescue and transport a patient with severe carbon monoxide poisoning (CO-Hb concentration 82%) was treated by hyperbaric oxygen (HBO) therapy in a pressure chamber. During decompression the patient suffered cardiac arrest due to massive acidosis, hyperpotassaemia, haemoconcentration and elevated CO-Hb level. After successful resuscitation and cardiopulmonary diagnostics, HBO therapy was continued for prophylactic treatment of delayed neurological sequelae. Three months after completing treatment and discharge from hospital there were no neurological sequelae.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
