Hypoxia-induced relaxation (HIR) response of isolated rat aorta rings in the CTRL, A-HBO2, 24H-HBO2, and 4D-HBO2 groups. HIR was significantly lower in A-HBO2 compared to all other groups of rats. The 24-HBO2 and 4D-HBO2 groups exhibited significantly increased HIR compared to CTRL and A-HBO2 groups of rats.
