Fig. 2From: Positive end-expiratory pressure titration in COVID-19 acute respiratory failure: electrical impedance tomography vs. PEEP/FiO2 tablesSpearman correlation between PEEPEIT and FiO2 (R = 0.075, p = 0.789). Continuous line: lower PEEP/FiO2 table. Dashed line: higher PEEP/FiO2 tableBack to article page
