Effects of etorphine (0.1 mg.kg −1 ) injected intramuscularly (time = 0) on measured arterial partial pressure of oxygen (PaO 2 , solid symbols) and the theoretical value of arterial partial pressure of oxygen calculated assuming that alveolar-arterial oxygen partial pressure gradient P(A-a)O 2 remained constant (Expected-PaO 2 , open symbols) (A), arterial partial pressure of carbon dioxide (B) and alveolar-arterial oxygen partial pressure gradient P(A-a)O 2 (C) in goats (mean ± SD, n = 12). # P < 0.05 pre-etorphine vs. post-etorphine (repeated measures two-way ANOVA with post hoc Sidak’s multiple comparison test (A) and repeated measures one-way ANOVA with post hoc Dunnett’s test (B&C)), * P < 0.05 PaO2 vs. expected-PaO2 (repeated measures two-way ANOVA with post hoc Sidak’s multiple comparison test (A)) at time 2, 6, 10 and 14 min.
