Physiological variables at certain time points in the control group (n = 6) and injury group (n = 5). Values represent the median [interquartile range]. HR, heart rate; MAP, mean arterial blood pressure; PaO₂, arterial oxygen tension; PaCO₂, arterial carbon dioxide tension; pH, arterial pH; RR, respiratory rate; SpaO₂, arterial oxygen saturation; T, body temperature; T₀, baseline; T₂₀, 20 minutes after acid aspiration (injury group) or after baseline (control group); T₁₁₀, 110 minutes after acid aspiration (injury group) or after baseline (control group). ^aP < 0.05 vs. T₀; ^bP < 0.05, Control vs. Injury.
