Lung ultrasound images used for aeration and B-line count scores. A: Example of lung ultrasound (LUS) images used for 8- and 12-region aeration scores using linear array probe (5.0–12.0 MHz). Left image: a line indicated by # (A pattern, 0 points); center image: ≥ 3 well-spaced B-lines indicated by * (B1 pattern, 1 point) with thickened pleura; right image: coalescent B-lines (B2 pattern, 2 points) with irregular, fragmented pleura. B: example of LUS images used for the B-line score using curved array probe (2.5–5.0 MHz). Left image: five B-lines, resulting in 5 points; right image: confluent B-lines taking up 100% of the intercostal space, resulting in 8 points. LUS  lung ultrasound
