Fig. 1From: Individualization of PEEP and tidal volume in ARDS patients with electrical impedance tomography: a pilot feasibility studyClinical protocol for prospective optimization of ventilator settings with electrical impedance tomography (EIT). Optimization started with an arterial blood gas (ABG) analysis and, if necessary, adjustments of respiratory rate (RR) and tidal volume (VT), followed by a recruitment maneuver (RM) and subsequent adaptations of positive end-expiratory pressure (PEEP) and VT.
