Table 1. Selected pleuro-pulmonary conditions detectable by lung ultrasound.

Disorder	Lung ultrasound findings	Reported performance	References
Pneumothorax	Absence of lung sliding, absence of B lines, lung point	Sensitivity: 89% [88–91], specificity: 99% [98–99], diagnostic OR: 993	(4)
Pleural effusion	Anechoic fluid with posterior acoustic shadowing above diaphragm	Sensitivity: 93% [89–96], specificity: 96% [95–98]	(21)
Pneumonia	B’ profile, A/B profile, consolidation, irregular pleural surface, dynamic air bronchograms	Sensitivity: 94% [89–96], specificity: 96% [94–97], + LR: 16.8 (7.7–370), − LR: 0.07 (0.05–0.10)	(5,17)
COPD/asthma	A profile with lung sliding	Sensitivity: 89%, specificity: 97%	(5)
Pulmonary edema	Diffuse B lines with intact lung sliding	Sensitivity: 93% [82–98], specificity: 89% [79–95]	(16)
ARDS	Heterogeneous B lines, ± lung sliding, subpleural consolidation	Sensitivity: 93–98%, specificity:78–100%	(3,5)
Interstitial lung disease	B lines in affected zones, B-7 for fibrosis, B-3 for ground glass	Unknown	(18)

OR, odds ratio; LR, likelihood ratio; ARDS, acute respiratory distress syndrome.
