– B Lines: indicates the number of B lines of the current frame. The number can be 1, 2, 3,
4, or ≥5. When the number is equal to or greater than 5, the system does not display a
specific number.
– Percent: indicates the percent of the B lines area against the total sampling area.
– Score: the score is among 0 to 3.
Normal: when there are a lung sliding sign and A line, or isolated B lines (<3), it is
marked as N in the brackets and the score is 0.
Moderate: when there are multiple clearly-distributed B lines, it is marked as B1 in the
brackets and the score is 1.
Severe: when there are intensively fused B lines, it is marked as B2 in the brackets and the
score is 2.
Lung consolidation: when the lung has a symptom that is similar to the liver lesion
structure and air bronchogram, it is marked as C in the brackets and the score is 3. When
the lung consolidation and pleural effusion occur at the same time, it is marked as C/P in
the brackets and the score is 3.
–Dist n (B Line distance): indicates the distance between the 2 neighboring lines and is
measured in the pleura line area, among which, n corresponds to the number between the
2 B lines.
– Avg Dist (B Line average distance): indicates the average distance of all B lines.
