New breathing test for ARDS patients shows promise
NCT ID NCT03462849
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at a new way to measure airway closure in patients with severe lung injury (ARDS) who are on breathing machines in the ICU. Researchers tested a simple method to see if the lungs are trapping air, which can help doctors adjust ventilator settings. The study involved 25 adults and focused on understanding lung function rather than providing a treatment.
