Can targeted breathing exercises help ventilator patients regain diaphragm strength?

NCT ID NCT07709793

Completed Disease control Sponsor: Chang Gung Memorial Hospital Source: ClinicalTrials.gov ↗

First seen Jul 17, 2026 · Last updated Jul 17, 2026

Summary

This study investigates whether high- or low-intensity inspiratory muscle training (IMT) better improves diaphragm function in patients who have been on mechanical ventilation for over 21 days. Using ultrasound, researchers will measure changes in diaphragm movement and thickness over up to two weeks of training. The goal is to determine which intensity level may lead to successful weaning from the ventilator.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
inspiratory muscle training (IMT) as a procedure
What this could lead to
If successful, this could help identify the best intensity of breathing exercises to help patients on ventilators regain diaphragm strength and breathe on their own sooner.
What could go wrong
This is a small, early-stage study with only 36 participants, so results may not apply to all patients. The training may not improve outcomes or could cause discomfort.
