Comparison of two recompression profiles in treating experimental cerebral airembolism. Undersea Biomed Res 1992; 19(3):171-185.-The standard treatment for cerebral arterial gas embolism (CAGE) is an initial recompression to 6 atm abs on air for 30 min followed by oxygen breathing at 2.8 and 1.9 atm abs. It has been suggested that initial recompression to 2.8 atm abs on 02 may be as beneficial, thus avoiding potential treatment complications associated with the deeper depth. To test this hypothesis, we measured the recovery of the somatosensory evoked potential (SEP) following air embolism in anesthetized, ventilated cats. Air was infused into the carotid artery in increments of 0.08 mi until the SEP amplitude was reduced to less than 10% of the baseline value for 15 min. Three groups were studied. A control group (n = 10) received no further treatment after SEP suppression. The second group (6 atm abs/HBO) (n = 8) was compressed to 6 atm abs on air for 30 min followed by 0, breathing at 2.8 atm abs for 100 min. The third group (HBO) (n = 8) was compressed to 2.8 atm abs on 02 for 130 min. The control
