This study will analyze lung tissue from 150 people with and without COPD using single-cell sequencing. The goal is to understand the molecular changes that drive the disease. Researchers hope this knowledge will point toward new ways to diagnose or treat COPD in the future.

This study looks at whether giving different oxygen levels during rest breaks between short cycling exercises helps people with COPD feel less breathless and exercise more easily. Fifty adults with moderate COPD will do four short cycling sessions with rest in between. Researcher…

This study looks at how long-term use of a BiPAP machine affects the diaphragm—the main breathing muscle—in people with advanced COPD. Researchers will use ultrasound to measure diaphragm thickness and movement over 6 weeks and 12 months in 30 patients. The goal is to learn wheth…

This study will examine tissue and blood samples from 105 adults having lung surgery to understand why some people with chronic lung disease develop pulmonary hypertension (high blood pressure in the lungs). Researchers will compare three groups: those with lung disease and pulmo…

This study looks at whether certain substances in the blood, like surfactant protein-D (SP-D), can help doctors predict how severe a COPD attack will be in hospitalized patients. Researchers will measure these markers in 75 adults admitted for a COPD flare-up and compare them to …
