Table 1 Quantitative evaluation of the lung injury after BTT based on alveolar hemorrhage (infiltration of red blood cells (rbcs)), alveolar infiltration (intra-alveolar cells), intra-alveolar fibrin and congestion of alveolar septae

From: Influence of obesity on remodeling of lung tissue and organization of extracellular matrix after blunt thorax trauma

Tissue 0 1 2 3
Alveolar hemorrhage None At least 5 rbcs/alveolus in 1–5 alveoli At least 5 rbcs/alveolus in 5–10 alveoli At least 5 rbcs/alveolus in > 10 alveoli
Alveolar infiltration No infiltration < 5 intra-alveolar cells/field 10–20 intra-alveolar cells/field > 20 intra-alveolar cells/field
Intra-alveolar fibrin None Fibrin in < 1/3 Fibrin in 1/3–2/3 Fibrin in > 2/3
Alveolar septae All thin and delicate Congested in < 1/3 Congested in 1/3–2/3 Congested in > 2/3
