One-lung ventilation requires the use of protective ventilation to limit ventilator-induced injury and reduce postoperative respiratory complications. Protective ventilation during one-lung ventilation is specific since tidal volumes are applied by definition to one lung, and it is recommended to use lower tidal volumes, down to 4 ml\u002Fkg of ideal body weight. This approach requires individualized ventilation parameters, which differs from the conventional or two-lung ventilation, and there are no clear recommendations regarding respiratory rate adjustment to ensure adequate gas exchange.",[59,60,61,62,63,64,65],"Thoracic","Surgery","Mechanical Ventilation","Hypercapnia","Acidosis","One Lung Ventillation (OLV)","Smartphone Application","2025-08-01",{"date":68,"type":69},"2025-08-06","ACTUAL",{"date":66,"type":69},{"date":72,"type":55},"2026-06",{"name":5,"class":6},1]
