From: A novel large animal model of smoke inhalation-induced acute respiratory distress syndrome
Effect of smoke duration in large animal. A, B Peripheral oxygen saturation (SpO2) level was measured in 1 h- and 2 h-smoke inhalation groups designated as “SI 1 h” and “SI 2 h”, respectively, at different time points from 0 to 48 h. A Statistical analysis of the delta SpO2 (designated as ΔSpO2) between SI 1 h and SI 2 h groups (B). ΔSpO2 for each group represented the difference in SpO2 level between baseline and 48 h post smoke exposure. C, D The ratio of partial pressure of arterial oxygen (PaO2) and fraction of inspired oxygen (FiO2), designated as “PaO2/ FiO2” was measured in SI 1 h and SI 2 h group of animals (C). Statistical analysis of the delta PaO2/FiO2 (designated as ΔPaO2/FiO2) between SI 1 h and SI 2 h groups (D). ΔPaO2/FiO2 for each group represented the difference in PaO2/FiO2 level between baseline and 48 h post smoke exposure. Smoke inhalation started at 0 h time point A p value of < 0.05 was considered statistically significant
