研究目的:

本研究通过随机对照试验,比较俯卧位与不同角度卧位(30°、90°、120°)对急性呼吸窘迫综合征(ARDS)患者肺功能改善的作用,利用电阻抗断层成像(EIT)技术实时监测通气分布、通气血流匹配等关键参数,并结合呼吸力学和血气分析数据,全面评估体位调整的疗效。研究假设高侧卧位可能减少俯卧位的不良并发症,同时有效改善氧合和肺功能。最终目标是为临床提供更安全、个体化的体位治疗方案,优化ARDS患者的治疗策略,降低死亡率并提高生存质量。  

Objectives of Study:

This randomized controlled trial investigates the effects of prone positioning versus lateral positioning at different angles (30°, 90°, 120°) on pulmonary function improvement in patients with acute respiratory distress syndrome (ARDS). Utilizing electrical impedance tomography (EIT) technology, the study monitors key parameters including ventilation distribution and ventilation-perfusion matching in real time, while integrating respiratory mechanics and blood gas analysis data to comprehensively evaluate the therapeutic efficacy of positional adjustments. The study hypothesizes that high-angle lateral positioning may reduce adverse complications associated with prone positioning while effectively improving oxygenation and pulmonary function. The ultimate objective is to provide a safer and more personalized positional therapy regimen for clinical practice, optimizing ARDS treatment strategies to reduce mortality and enhance patient survival outcomes.
