Abstract: Perioperative mechanical ventilation-induced lung injury has become a globally recognized issue, and enhancing perioperative lung protection can significantly reduce the occurrence of pulmonary complications and promote early patient recovery. There have been studies indicating a close relationship between intraoperative mechanical ventilation strategies and perioperative lung injury. Pressure-Controlled Volume Guaranteed Ventilation(PCV-VG)is an emerging ventilation mode that can provide stable tidal volumes without being affected by changes in airway pressure. It achieves appropriate ventilation and oxygen supply by ensuring that the airway pressure remains within a predetermined limit. This review is to comprehensively evaluate the impact of PCV-VG mode on perioperative lung injury and outcomes, including hemodynamics, respiratory mechanics, inflammatory mediators, oxygenation indices, and postoperative complications, among other key factors. It also aims to compare the application effects of different ventilation modes in specific patient populations, providing more reliable evidence for clinicians in choosing ventilation strategies.
