Fig. 5From: Bedside selection of positive end-expiratory pressure by electrical impedance tomography in hypoxemic patients: a feasibility studyCorrelations between recruited volume, compliance and oxygenation. The amount of recruited volume did not correlate with oxygenation improvement (R 2 = 0.04, p = 0.448), whereas it correlated with the improvement in respiratory system compliance (R 2 = 0.50, p < 0.01)Back to article page
