研究目的:

1.评估rPMS对膈肌和肋间肌功能的改善效果:通过床旁超声定量评估rPMS干预前后膈肌厚度、活动度及增厚分数的变化和肋间肌厚度及增厚分数的变化,明确其改善膈肌和肋间肌收缩功能的效果。 2.评估rPMS对腹部肌肉的影响:通过床旁超声定量评估rPMS干预前后腹内斜肌、腹外斜肌、腹横肌、腹直肌厚度及增厚分数的变化,评估其改善咳嗽能力的效果。 3.确定rPMS对脱机成功率的影响:比较干预组与对照组成功脱机率、机械通气时间及ICU住院时间,验证rPMS提高拔管成功率的临床价值。  

Objectives of Study:

1. Evaluate the improvement effect of rPMS on the function of the diaphragm and intercostal muscles: Through bedside ultrasound, quantitatively assess the changes in diaphragm thickness, mobility and thickening fraction before and after rPMS intervention, as well as the changes in intercostal muscle thickness and thickening fraction. Clearly determine the effect of rPMS in improving the contraction function of the diaphragm and intercostal muscles.2. Evaluate the effect of rPMS on abdominal muscles: Through bedside ultrasound, quantitatively assess the changes in the thickness and thickening fraction of the internal oblique muscle, external oblique muscle, transverse abdominal muscle and rectus abdominis muscle before and after rPMS intervention, and evaluate its effect in improving the coughing ability.3. Determine the effect of rPMS on the success rate of weaning from mechanical ventilation: Compare the success rate of weaning, mechanical ventilation time and ICU hospitalization time between the intervention group and the control group to verify the clinical value of rPMS in improving the success rate of extubation.
