PaO₂/FiO₂ and total oxygen content reduced in smoke inhalation induced lung injury. A The ratio of PaO₂ and FiO₂, designated as “PaO₂/FiO₂” was measured in SI group of animals at baseline, 2 h, 24 h, and 48 h time points. B Delta PaO₂/ FiO₂ (ΔPaO₂/FiO₂) values were calculated between baseline and different time points. C Total arterial oxygen content (CaO₂) and total mixed venous oxygen content (CmvO₂) levels were measured in SI group at baseline, 2 h, 24 h and 48 h time points. D Delta CaO₂ (ΔCaO₂) and delta CmvO₂ (ΔCmvO₂) values were calculated between baseline and different time points (D). Delta value for each parameter represented the difference with the corresponding baseline values. PaO₂/FiO₂ and CaO₂ and levels were measured at 24 h for n = 8 and n = 6 respectively; CmvO₂ level was not measured at 24 h time line. Smoke inhalation started at 0 h time point. A p value of < 0.05 was considered statistically significant
