Summary

Prolonged mechanical ventilation (PMV) and weaning failure can lead to extended hospital stays, as well as increased morbidity and mortality during hospitalization. Therefore, PMV not only increases the economic burden on patients and their families, but also adds to the societal economic burden and consumes critical care medical resources. Inspiratory muscle training (IMT) is widely used by physical therapists in critically ill patients to improve respiratory function and enhance quality of life. IMT helps improve diaphragmatic function, and the improvement of diaphragmatic function in turn promotes better respiratory function, which is clinically significant for accelerating weaning. However, most studies on the effects of IMT on weaning success rates and the duration of mechanical ventilation have limitations such as small sample sizes, homogeneous patient populations, and short intervention periods. As a result, there is still no unified, high-quality evidence-based consensus. The purpose of this study is to further clarify the role of IMT in improving diaphragmatic function and increasing weaning success rates in patients with prolonged weaning, through clinical treatment and the collection and analysis of relevant data.
