Progress in the Application of Lung Ultrasound for the Evaluation of Neonates with Respiratory Distress Syndrome

Figures & data

Table 1 Brat lung ultrasound scoring

0 Point	1 Point	2 Points	3 Points
Presence of only an “A-line”	Presence of ≥ 3 well-spaced B-lines	AIS with or without consolidation localized beneath the pleura	Widespread consolidation

Table 2 12-zone lung ultrasound scoring

0 Point	1 Point	2 Points	3 Points
Normal ventilation: Presence of A-line with occasional sporadic B-lines	Moderate reduction in lung ventilation with interstitial lung syndrome and localized pulmonary edema (with merged B-lines occupying < 50% of the intercostal space when viewed in a cross-section)	Severe reduction in lung ventilation: Alveolar edema (with merged B-lines occupying the entire intercostal space when viewed in a cross-section)	Lung consolidation

Table 3 14-zone lung ultrasound scoring

0 Point	1 Point	2 Points	3 Points	4 Points	5 Points
Mainly A-line with sporadic (< 3) B-lines	Presence of scattered, non-confluent B-lines	Dense, partially confluent B-lines	Completely merged B-lines	Abnormal pleural line with small range (depth < 1 cm) subpleural lung consolidation	Abnormal pleural line with extensive (depth > 1 cm) lung consolidation
