Comparison of Two Strategies of One-lung Ventilation in Patients Undergoing Carcinological Lung Resection Surgery.

"In the open-lung group, the positive end-tidal pressure (PEEP) is titrated to match the best lung compliance. During a PEEP decrement trial, PEEP is decreased from 20 cmH2O to 4 cmH2O by steps of 2 cmH2O/minute, and the driving the transpulmonary pressure (PTP) is calculated at each level of PEEP. In the open-lung group, the targeted PEEP corresponds to the lowest driving PTP during the PEEP decrement trial, meaning the best lung compliance. Thereafter, the PEEP is set at this level and maintained until extubation."

"In the standard group, the positive end-tidal pressure (PEEP) is arbitrarily set at 5 cmH2O, since this is the currently recommended level of PEEP, commonly used in control groups of previous clinical trials."
