To stratify the severity of inhalation injury on chest CT.

Use in patients with suspected or diagnosed inhalation injury and conjunction with flexible bronchoscopy. Instruction: RADS requires chest CT to calculate. This tool computes RADS for a single slice; to obtain a full score (average RADS per slice), add RADS for all slices and divide by a number of slices. Variables and assigned points (Normal=0, Increased interstitial markings=1, Ground glass opacification=2, Consolidation=3): - Worst finding, 1st quadrant left lung - Worst finding, 2nd quadrant left lung - Worst finding, 3rd quadrant left lung - Worst finding, 4th quadrant left lung - Worst finding, 1st quadrant right lung - Worst finding, 2nd quadrant right lung - Worst finding, 3rd quadrant right lung - Worst finding, 4th quadrant right lung RADS Formula: Addition of the selected points. Interpretation: - RADS ≤8 associated with a lower risk of composite endpoint including pneumonia, acute lung injury/ARDS, and death. - RADS >8 associated with 12.7x increased risk of composite endpoint including pneumonia, acute lung injury/ARDS, and death.
