Effect of resuscitation gas on hemispheric flux. Median (with range) flux values for the ligated and unligated hemisphere during resuscitation with 21% oxygen or 100% oxygen, and subsequent recovery. Median values for each animal, over both time periods, were compared between groups

Period	Cerebral blood flux (au)
	21% Oxygen		100% Oxygen
	Ligated	Unligated	Ligated	Unligated
Resuscitation	274 (228–539)	442 (327–657)	396 (260–592)*	501 (342–736)
Recovery	278 (182–462)	478 (290–651)	368 (236–520)	441 (328–679)

*Denotes P < 0.05 compared to ligated hemisphere in the 21% oxygen group.
