Relationship between neonatal respiratory distress syndrome pulmonary ultrasonography and respiratory distress score, oxygenation index, and chest radiography grading

Figure 2 X-ray grade 1 respiratory distress syndrome neonatal pulmonary ultrasonography images. A, B, E: Representative images showing increase in B-lines in the anterior chest of R1–R2/L1–L2. Real-time ultrasonography shows that B-lines and A-lines alternate with lung slip, resulting in 1 point each; C, D, F, G: Representative images showing ground-glass-like changes in each region of R3–R4/L3–L4 R5–R6/L5–L6, with 2 points each and a total ultrasonography score of 10 points.
