Changes in Lung Function Parameters in PBLI. (A) PO₂ (F = 8.893, p < 0.001) showed statistically significant differences between injury grades, with PO₂ levels decreasing in minor PBLI at 0.5 h (p < 0.001) and 12 h (p = 0.011); in moderate PBLI, PO₂ decreased at 0.5 h (p < 0.001), 3 h (p = 0.008), 6 h (p = 0.001), 12 h (p = 0.004), and 24 h (p = 0.017); in severe and serious PBLI PO₂ decreased at 0.5 h (p < 0.001), 3 h (p = 0.006), 6 h (p < 0.001), 12 h (p < 0.001), and 24 h (p = 0.001) . (B) PCO₂ (F = 1.997, p = 0.026) showed that in minor PBLI PCO₂ decreased at 0.5 h (p = 0.001) and 6 h (p = 0.011), in moderate PBLI PCO₂ decreased at 0.5 h (p < 0.001), 3 h (p = 0.006), 6 h (p = 0.001), 12 h (p < 0.001), and 24 h (p = 0.001), in severe and serious PBLI PCO₂ increased at 0.5 h (p < 0.001), while it decreased at 3 h (p = 0.008), 6 h (p = 0.001), 12 h (p = 0.004), and 24hs (p = 0.017). (C) AaDO₂ (F = 17.107, p < 0.001) showed that in minor PBLI AaDO₂ decreased at 0.5 h (p < 0.001), 3 h (p = 0.009), 6 h (p < 0.001), and 12 h (p = 0.005), in moderate PBLI AaDO₂ decreased at 0.5 h (p < 0.001), 3 h (p < 0.001), 6 h (p < 0.001), 12 h (p < 0.001), and 24 h (p < 0.001),in severe and serious PBLI AaDO₂ decreased at 0.5 h (p < 0.001), 3 h (p = 0.001), 6 h (p < 0.001), 12 h (p < 0.001), and 24 h (p < 0.001). *p < 0.05, †p < 0.01, $p < 0.001. Comparisons were made using RM ANOVA between groups and within groups at each time point post-injury vs. pre-injury.
