Four hundred and eighty\u2010three patients ASA 3\u20135, scheduled for major surgery under general anaesthesia, were included. Patients were randomised to positive end\u2010expiratory pressure (PEEP) of 5, 8, or 10\u2009cm H\n                      <jats:sub>2<\/jats:sub>\n                      O, tidal volume of 6, 8, or 10\u2009mL\/kg, and fraction of inspired oxygen (FiO\n                      <jats:sub>2<\/jats:sub>\n                      ) of 30% or 80%. The primary outcome was feasibility of delivering the ventilatory interventions, while secondary outcomes included intra\u2010 and postoperative complications, hospital length of stay, quality of life and recovery, and mortality.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Feasibility goals were not met, but clear separation within each intervention was achieved.
