Effect of IMT in Patients After Acute Exacerbations of COPD

"home-based inspiratory muscle training (IMT) will be delivered using a portable IMT device connected via Bluetooth to a smartphone application that provides real-time feedback, adherence monitoring, and telemonitoring by the study team. Patients will train for 365 days following hospital discharge due to an acute exacerbation of COPD:~* Intensive phase (Day 0-90): 2 daily sessions, each consisting of 30 breaths against an inspiratory load set by thetelemonitor, with regular online supervised IMT sessions, 7 sessions in total~* Maintenance phase (Day 91-180): One daily session of 30 breaths, with sporadic online supervised IMT sessions, 2 sessions in total.~* Follow-up phase (Day 181-365): Participants may continue IMT unsupervised. Supervision includes both in-person sessions at hospital visits and online sessions with telemonitors."
