Correlation between ultrasound reaeration score and lung inflation induced by early (A) and late (D) prone positioning (upper panel). Lung inflation was measured as end-expiratory lung volume (EELV) using the multibreath nitrogen-wash-out technique. Accuracy of lung ultrasound score for estimating early (B) and late (E) prone positioning induced lung inflation. Correlation between ultrasound reaeration score and early (C) and late (F) prone positioning induced increase in PaO2. Early and late time points correspond to study assessments made at 1 h and 16 h after prone positioning onset, respectively. Each closed circle represents an individual patient. Gray lines represent 95% confidence intervals. Black circles represent patients with diffuse loss of aeration; open circles represent patients with focal loss of aeration. Anatomical mapping of lung ultrasound reaeration score changes induced by prone positioning (lower panel). Graphical representation as a two-dimensional polar coordinate system of LUS reaeration score across the prone positioning session for each group (responders vs. not responders). Patient’s response to prone positioning was defined by EELV equal or greater than 500 ml. Comparison between groups was made using a Mann–Whitney test. Significant difference correspond to a p value < 0.05. LUS lung ultrasound, PP prone position
