New study aims to decode which lung test best predicts breathing relief

NCT ID NCT07364188

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study will enroll 120 adults with asthma or COPD to see how changes in lung function tests (spirometry and impulse oscillometry) relate to how much their breathing improves after using a bronchodilator. Participants will take a standard reversibility test and report their symptom relief on a scale. The goal is to find the smallest meaningful change in these tests that matches real-world breathing improvement.
