In recent years, inspiratory muscle training (IMT) has been widely used by physical therapists in critically ill patients to improve their respiratory function and enhance their quality of life. IMT is safe and feasible for a specific group of patients dependent on ventilators . This training not only improves inspiratory muscle strength but also increases the possibility of patients successfully being weaned off ventilators . In addition, patients who successfully weaned off the ventilator and continued with IMT also helped improve their quality of life. The current health status measured by EQ-5D VAS indicated that the symptoms of the inspiratory muscle training group improved by 12% compared with the control group. Therefore, IMT may serve as one of the training methods for physical therapists to improve the diaphragmatic function of patients with delayed weaning and increase the success rate of weaning.
In terms of the impact on the success rate of weaning from aircraft, the results of multiple randomized controlled trials and meta-analyses indicate that IMT plays a positive role in enhancing the success rate of weaning from aircraft. The results of a randomized clinical trial showed that the weaning time of the IMT group was significantly shorter than that of the control group, specifically 12.6 days compared with 18.1 days, with a P value of 0.04. This indicates that IMT can effectively shorten the duration of mechanical ventilation, thereby increasing the possibility of successful weaning. Marine pointed out in a recent article that both high-intensity IMT and low-intensity IMT can improve the MIP of patients with mechanical ventilation, increase the success rate of weaning from the ventilator and reduce the duration of mechanical ventilation, but there is no significant difference between the two groups. In addition, in this study, the forced vital capacity (FVC) of the patients increased more in the high-intensity IMT group. The absence of significant differences between the two groups in this study might be due to the fact that the study only lasted for 4 weeks, which was a relatively short intervention period. Furthermore, another systematic review revealed that although IMT could improve maximal inspiratory pressure and the Rapid Shallow Breathing Index (RSBI), no significant difference was found in the success rate of weaning from the ventilator, indicating that although IMT can enhance the strength of respiratory muscles, But it does not necessarily directly lead to a higher success rate of flight withdrawal. The effect of IMT on patients with difficult weaning due to different causes also varies. For instance, IMT studies on patients with chronic obstructive pulmonary disease (COPD) have shown that IMT not only enhances respiratory muscle strength but also improves lung function indicators, thereby improving the weaning effect. However, other studies have pointed out that the effect of IMT in patients with neuromuscular diseases is relatively limited, possibly because these patients themselves have more complex respiratory muscle weakness problems. Regarding the research on the success rate of weaning from the ventilator and the duration of mechanical ventilation by IMT, most studies have problems such as small sample size, single patient population and short intervention time. Therefore, there is no unified and high-quality evidence-based basis yet.
In conclusion, IMT helps improve diaphragmatic function, and the improvement of diaphragmatic function will promote the improvement of respiratory function in patients, which also has certain clinical significance for accelerating weaning from the ventilator. Under the condition that our department is equipped with multiple physical therapists with experience in implementing IMT, the assessment and intervention of patients with delayed weaning in the intensive care unit were completed through the joint efforts of medical, nursing and technical staff. The success rate of weaning was the main result, and the diaphragm mobility, diaphragm thickness and diaphragm thickening fraction in the diaphragm ultrasound results were the secondary results to conduct this study. The aim is to further clarify the impact of inspiratory muscle strength training on the successful weaning of patients with delayed weaning and the improvement of diaphragmatic function through clinical treatment and data collection and analysis.
