 Lung protective ventilation(LPV)is crucial in efforts to minimize the risk of the occurrence of a ventilator-associated lung injury(VALI)during the perioperative period. Conventional LPV strategies focusing on the tidal volume and plateau pressure have limitations in assessments of individual patients’ lung stress. The driving pressure(ΔP), i.e., the change in airway pressure during tidal ventilation, reflects dynamic lung strain. The transpulmonary pressure(Pl), i.e., the pressure distending the lungs, represents the true stress on the lung parenchyma. A lower ΔP value is associated with improved outcomes in patients with ARDS, and a high intraoperative ΔP is an independent risk factor for postoperative pulmonary complications(PPC). Pl-guided PEEP titration can personalize ventilation, especially in patients with altered chest wall mechanics, obesity, or the requirement of a specific surgical position. The emerging concept of transpulmonary driving pressure(ΔPl)may offer a more precise measure of dynamic lung strain. Although the variables ΔP and Pl are key to advancing individualized respiratory support, it is also essential to conduct further high-quality research, standardize measurement techniques, and develop noninvasive estimation methods for widespread clinical implementation and for improving patient outcomes. This review discusses the physiological basis, historical evolution, and clinical applications of ΔP and Pl for optimizing the use of LPV in perioperative settings.
