From: Factors for success of awake prone positioning in patients with COVID-19-induced acute hypoxemic respiratory failure: analysis of a randomized controlled trial

Fig. 2

Physiological response to awake prone positioning according to subgroups of treatment success and failure. a RR decreased by 1.5 breaths/min in patients with treatment failure vs 3.7 breaths/min in patients with treatment success after the first APP session. b SpO2/FiO2 ratio increased by 12 in patients with treatment failure vs 18 in patients with treatment success after the first APP session. c ROX index increased by 0.7 in patients with treatment failure vs 2.3 in patients with treatment success after the first APP session. d LUS score decreased 2.4 points in patients with treatment success, while patients with treatment failure had no change after 3 days. RR, respiratory rate; APP, awake prone positioning; LUS, lung ultrasound score
