Nonetheless, by putting at rest the respiratory muscles, it can lead to respiratory muscle weakness and atrophy, which are accompanied by prolonged duration of mechanical ventilation, difficult weaning and increased ICU mortality. Despite a strong theoretical rationale and some evidence supporting the use of inspiratory muscle training (IMT) to address respiratory muscle weakness and atrophy, the optimal approach to IMT remains largely uncertain. In fact, mechanistic studies evaluating physiological adaptations that occur in respiratory muscles of mechanically ventilated patients in response to different training regimens have not been conducted so far.\n\nThe aim of this study is to comprehensively investigate changes in respiratory muscle function in response to three different conditions that patients will be exposed to during their period of weaning from mechanical ventilation.",[79],"Weaning Failure",[81,82,83,84,85,86,87,88,89,90],"ICU acquired muscle weakness","IMT","Weaning outcomes","Maximal inspiratory pressure","Diaphragm EMG","Surface EMG","Diaphragm ultrasounds","Microbiopsies","Difficult to wean patients","Respiratory muscles","2026-03-16",{"date":93,"type":94},"2026-03-18","ACTUAL",{"date":96,"type":94},"2023-02-01",{"date":98,"type":73},"2026-10",{"name":5,"class":6},1]
