研究目的:

利用EIT技术评估延长俯卧位时间对肺通气和血流的影响,同时探讨其对气体交换、呼吸力学和血流动力学的作用,从而为临床实施个体化俯卧位治疗提供依据和思路。  

Objectives of Study:

To evaluate the effects of prolonged prone positioning on lung ventilation and perfusion using electrical impedance tomography (EIT), and to explore its impact on gas exchange, respiratory mechanics, and hemodynamics, thereby providing evidence and insights for individualized prone positioning therapy in clinical practice.
