Summary

This study observes how the diaphragm works in 100 adults with acute respiratory failure who need non-invasive breathing support or high-flow oxygen. Researchers use ultrasound to measure diaphragm movement and thickness at different support levels. The goal is to understand how these measurements relate to breathing improvement and the need for a breathing tube. No new treatments are tested; this is purely observational.
