Within the compressed gas diving arena there is a risk of cerebral damage with deleterious neuropsychological sequelae in association with decompression illness (DCI), hypoxia, gas toxicity, as well as the cumulative subclinical effect of 'silent' paradoxical gas embolisms, the last being an area of growing concern. However, within diving medicine ...
