- Patients who fail to wean from mechanical ventilation are at higher risk of morbidity and death.
- Dyspnea due to respiratory muscle weakness contributes to failure to wean (FTW).
- Respiratory muscle training was improved the respiratory muscle strength in patients on long-term mechanical ventilation.
- All patients were successfully weaned from mechanical ventilation after 9 to 28 days.
RMT by IMST effectively improves weaning success after mechanical ventilation.
Patients on mechanical ventilation for an average of 72 days received daily IMT. Maximal inspiratory pressure (MIP) was assessed weekly, and unassisted breathing trials (UBT) were performed regularly. Patients were considered weaned when they were able to breathe unassisted for 48 hours.
All patients showed significant increases in MIP and were weaned off mechanical ventilation within nine to 28 days.
Increase of respiratory muscle strength by IMT in patients on long-term mechanical ventilation greatly supports successful weaning.
