Fig. 5From: External chest-wall compression in prolonged COVID-19 ARDS with low-compliance: a physiological studyEffect of ECC on pleural pressure (Ppl) Gradient in pigs with experimental ARDS. N = 4. Ppl gradient was calculated as Ppl dorsal–Ppl ventral, both at end-inspiration (white dots) and end-expiration (black dots).
