From: Lung ultrasound response to awake prone positioning predicts the need for intubation in patients with COVID-19 induced acute hypoxemic respiratory failure: an observational study

Fig. 3

Response in regional lung ultrasound (LUS) score to the first APP session on the first day and the first three days. Radar plots show the response in LUS score for patients with treatment success to the first session of APP and after three days. Each axis of the plots represents LUS score of a single lung zone, with the response observed as the change from red (before APP) to gray (1 h after APP) and blue (after supine) lines. For patients with treatment success, LUS score in both dorsal lung zones (LD1, LD2, RD1, and RD2) and some lateral zones (LL2 and RL2) decreased at the first session of APP (a) and after three days (b). While for patients with treatment failure, LUS score did not change in all lung zones at the first session of APP (c) and after three days (d), except for LD1 after three days.
