Highlights
There are six LUS image patterns can be found in infants who just birth, including four “low-risk” patterns and two “high-risk” patterns.
The number of scanning regions with “high-risk” patterns has a great predictive value for respiratory support.(AUC = 0.95, optimal cut-off value is 2 with a sensitivity of 87.10% and specificity of 88.02%)
The predictive value of LUS is greater than that of assessment method based on respiratory symptoms.(e.g. respiratory rate)
