Cardiac arrest from gas embolism in scuba diving.
The case of a scuba diver who suffered a cardiac arrest is presented. The history of a short, lucid interval after surfacing followed by cardiac arrest, the finding of hemoptysis, and the characteristic response to recompression therapy are consistent with the diagnosis of gas embolism. The clinical presentation and pathophysiology of gas embolism are discussed, and an approach to emergency stabilization and definitive management of gas embolism is reviewed, with emphasis on cardiac arrest.
