研究目的:

1.主要目的:?评估俯卧动态角度调节联合手法胸壁振荡技术(每日8小时干预)对中重度急性呼吸窘迫综合征(ARDS)患者通气血流比(V/Q)改善及氧合状态的影响,重点分析其对血气指标(PaO2/FiO2、AaDO2)、肺部感染控制(CPIS评分)及呼吸机参数优化的临床疗效。 2.?次要目的?:验证每日8小时干预时长的可行性及安全性,明确其对缩短机械通气时间、降低ICU住院时间的实际效果;探索体位动态角度调节与高频振荡技术协同改善肺复张、减少肺不张的潜在机制。  

Objectives of Study:

1. Main objective: To evaluate the effect of prone dynamic angle adjustment combined with manual chest wall oscillation technique (8-hour daily intervention) on the improvement of ventilation blood flow ratio (V/Q) and oxygenation status in patients with moderate to severe acute respiratory distress syndrome (ARDS), with a focus on analyzing its clinical efficacy on blood gas indicators (PaO2/FiO2, AaDO2), pulmonary infection control (CPIS score), and ventilator parameter optimization. 2. Secondary objective: To verify the feasibility and safety of an 8-hour daily intervention duration, and to clarify its actual effect on shortening mechanical ventilation time and reducing ICU hospitalization time; Exploring the potential mechanism of synergistic improvement of lung recruitment and reduction of atelectasis through dynamic angle adjustment of body position and high-frequency oscillation technology.

随机方法(请说明由何人用什么方法产生随机序列):

采用区组随机法(Block Randomization),通过计算机生成随机序列(随机种子数保密)。 患者按 1:1 比例分配至实验组(Prone-HFCWO 干预)或对照组(传统俯卧位)。 区组大小为 4,确保各组在每个区组内人数均衡。

Randomization Procedure (please state who generates the random number sequence and by what method):

The block randomization method was employed, with a random sequence generated by a computer (the random seed number is kept confidential). Patients were allocated in a 1:1 ratio to either the experimental group (Prone-HFCWO intervention) or the control group (traditional prone positioning). The block size is 4, ensuring that each group has an even number of people within each block.

盲法:

因干预措施操作可见(体位调节+振荡技术),对操作人员及患者不设盲。 结局评估者(数据统计人员、影像学判读者)设盲,避免测量偏倚。

Blinding:

Due to the visible operation of the intervention measures (posture adjustment + oscillation technique), there is no blinding for the operators and patients. The outcome assessors (data statisticians, radiology readers) were blinded to avoid measurement bias.
