Modified Lung Ultrasound Score for Assessing and Monitoring Pulmonary Aeration

Lung Ultrasound Score (LUSS)  is a useful tool for lung aeration assessment but presents two theoretical limitations.  Standard LUSS is based on longitudinal scan and detection of number/coalescence of B lines. But in the longitudinal scan pleura visualization is limited by intercostal space width. Moreover, coalescence of B lines to define severe loss of aeration is not suitable for non-homogeneous lung pathologies where focal coalescence is possible. We therefore compared longitudinal vs. transversal scan and also cLUSS (standard coalescence-based LUSS) vs. qLUSS (quantitative LUSS based on % of involved pleura).
