Figure 1

PEEP optimization procedure according to optimal Xrs. The upper panel shows tracheal pressure and the lower panel shows respiratory system reactance (Xrs) measured at end-expiration over time during a representative positive end-expiratory pressure (PEEP) optimization procedure. PEEP was increased up to 20 cmH2O, and then decreased in one-minute steps of 2 cmH2O while Xrs was continuously monitored. When Xrs started to decrease, PEEP was increased back to 20 cmH2O and finally set to the PEEP level corresponding to the maximum Xrs.
