Percent change in te from baseline was calculated before (A, n = 7; B, n = 9) and after administration of vehicle (A, n = 8) or dizocilpine at low (A, n = 7) or high (B, n = 9) dose at following 5 points: before hypoxia (baseline), during peak breathing frequency (Pk f) and last 3 breaths in hypoxia (end), during maximal prolongations in te after hypoxia (max te), and 30 s later. Respiratory response to hypoxia in low-dose group was similar to pattern before treatment and after vehicle administration, except that te during peak hypoxic frequency had significantly increased compared with baseline te (* P = 0.02). After high dose of dizocilpine, peak frequency te was not significantly different, but percent change in te at maximal te and 30 s later was significantly decreased compared with baseline level (B; ** P = 0.003 and 0.003, respectively).
