Hypobaric-hypoxic ventilatory response (HHVR) (A) Representative traces of ventilatory flow from one Veh rat and one OXY rat (left panel) during normobaric normoxia (NN) (sea level, pO2 155 mmHg) and hypobaric hypoxia (HH). (B) Both animal groups display similar HHVR without significant differences (right panel) (n = 6 for each group)
