Figure 2. — Setting personalized positive end-expiratory pressure (PEEP) at the bedside. ARDS = acute respiratory distress syndrome, CoV = center of ventilation, CRS = respiratory system compliance, EELV = end-expiratory lung volume, EIT = electrical impedance tomography, GI = global inhomogeneity index, OD-LC = overdistension and lung collapse, PBW = predicted body weight, P_ES = esophageal pressure, Ple = transpulmonary expiratory pressure, PLR = potential for lung recruitment, PLR_CT = CT-based PLR, PLR_INFL = PLR based on lung inflation, Pplat = plateau pressure, PplatL = transpulmonary plateau pressure, R/I ratio = recruited-on-inflated lung ratio, Spo₂ = peripheral oxygen saturation, SS = silent spaces, VTe = exhaled tidal volume, V_DEP = dependent regions tidal volume (based on impedance tidal changes), V_NDEP = nondependent regions tidal volume (based on tidal impedance changes), ΔSS = change of silent spaces at higher PEEP.
