Fig. 3From: Bedside selection of positive end-expiratory pressure by electrical impedance tomography in hypoxemic patients: a feasibility studyCorrelation between PEEP and FiO2 set according to ARDSnet and EIT: As expected, there was a strong correlation between PEEPARDSnet and FiO2 set according to ARDSnet table (R 2 = 0.80, p < 0.001); on the contrary, no significant association was observed between PEEPEIT and predicted FiO2 (R 2 = 0.12, p = 0.217)Back to article page
