Regions of ultrasound examination. A: Figure depicting the positions for lung ultrasound (LUS) examination of the anterior (points 1 and 2), lateral (points 3 and 4) and posterior (points 5 and 6) regions (example using the right hemithorax). Regions were used for obtaining images for the global LUS score (6 regions per hemithorax, score range 0–36 points) and LUS–ARDS score (6 regions per hemithorax, score range 0–91 points). B: Ventral view of the thorax, depicting the 8 regions used for the anterior–lateral score (4 regions per hemithorax, score range 0–24 points). The four anterior points (R1, R2, L1, L2) were used for the aggregation of the B-line count score (2 regions per hemithorax, score range 0–32 points)
