AbstractDespite the maturity and sophistication of anaesthesia workstations, improvements in our understanding of intraoperative mechanical ventilation, and use of less invasive surgical techniques, postoperative pulmonary complications (PPCs) are still a common problem in surgical patients of all ages. PPCs are associated with a higher incidence of perioperative morbidity and mortality, longer hospital stays, and higher healthcare costs. PPCs are strongly associated with anaesthesia-induced atelectasis, which predisposes to lung damage when partially collapsed lungs are subjected to mechanical ventilation. Lung protective ventilation is thus a modifiable factor that can positively impact the incidence of PPCs after surgery. Intraoperative protective ventilation strategies have been based on two main but intrinsically different hypotheses: one based on sole reduction of tidal volume and pressures, using minimal positive end-expiratory pressure (PEEP), tolerating the presence of lung collapse, and the other also limiting tidal volume and pressures after actively resolving atelectasis by lung recruitment and PEEP individualisation, the individualised open-lung approach. We review the concepts of the individualised open-lung approach, its potential benefits, and outstanding questions. We conclude with a proposal for personalised lung protective ventilation.Copyright © 2024 British Journal of Anaesthesia. Published by Elsevier Ltd. All rights reserved.
