Evaluating muscle oxygenation in COPD patients during respiratory fatigue
Official title: Examining the Relationship Between Respiratory Muscle Fatigue and Lower Extremity Muscle Oxygenation in Chronic Obstructive Pulmonary Disease Patients.
Run by Istanbul Medipol University Hospital · NCT06217276 · Data updated 2026-11-12
This study is testing how muscle oxygen levels change in people with COPD during breathing fatigue to see how it compares to healthy individuals.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include individuals diagnosed with Stage 2-3 COPD who have been stable on their medications for at least four weeks.
✕Probably not a fit
Patients with severe comorbidities, recent acute COPD exacerbations, or other significant respiratory diseases may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study investigates changes in oxygenation levels of the vastus lateralis muscle in patients with Stage 2-3 COPD using the Moxy device, which measures functional infrared oxygen levels. Participants will undergo a respiratory muscle fatigue protocol to assess how their muscle oxygenation responds compared to healthy controls. The study aims to provide insights into the relationship between respiratory muscle fatigue and lower extremity muscle oxygenation in COPD patients.
Why it matters
Potential benefit: If successful, this study could enhance understanding of muscle oxygenation in COPD, potentially leading to improved management strategies for patients.
How similar studies have gone: While the specific approach of this study may be novel, similar studies have explored muscle oxygenation in respiratory conditions, indicating potential for meaningful insights.
