Background: Postoperative pulmonary complications are common and highly morbid, particularly in thoracic surgery patients. Previous reports have demonstrated that protective ventilation can improve postoperative pulmonary function and reduce the incidence of complications, but the precise definition of protective ventilation remains elusive. The aim: The aim of this study to show about one lung ventilation during thoracic surgery comparing the safety and efficacy of low and high tidal volume. Methods: By the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020, this study was able to show that it met all of the requirements. This search approach, publications that came out between 2014 and 2024 were taken into account. Several different online reference sources, like Pubmed, SagePub, and Sciencedirect were used to do this. It was decided not to take into account review pieces, works that had already been published, or works that were only half done. Result: Eight publications were found to be directly related to our ongoing systematic examination after a rigorous three-level screening approach. Subsequently, a comprehensive analysis of the complete text was conducted, and additional scrutiny was given to these articles. Conclusion: Low tidal volumes (defined as less than 10 mL/kg) decreases pneumonia and the need for postoperative ventilatory support (invasive and non‐invasive).
