Labored Breathing Index (LBI) and percentage change of this parameter from baseline injury (BI) over time (post injury-50% FIO2 and over hour 1 through 4) in Heliox group (solid line with open triangles) vs Nitrox group (dashed line with open squares). (a) Heliox group compared to Nitrox group had significantly lower LBI values over time (* P < 0.01). (b) Percentage change in LBI normalized to baseline injury on y-axis plotted against time from post injury and over 4 hours of spontaneous breathing. Heliox group has significantly greater percentage drop in LBI over time (* P < 0.01).
