from haemodynamic and metabolic investigation of 65 comatose subjects following cranial traumatism or cerebral vascular accident , the following prognostic and therapeutic indications emerged : the isolated increase in oxygen pressure in the jugular vein to above 50 mm hg , the simultaneous decrease in circulation of the brain to below of 30 ml/100g/min. , and of the brain consumption of oxygen to below 1.5 ml/100g/min. , combined with a loss of autoregulation and a decrease in carbon dioxide reactivity indicate that prognosis is very poor .
