Recognition of Early Pulmonary Structural Changes by Using Real-time High Fidelity Expiratory CO2 Analysis
Source: ClinicalTrials.gov · Last updated 21 Jan 2026
Brief summary (registry, in English)
In this study the investigators aim to detect and characterize structural airway and lung vessel changes due to COPD or ILD as assessed by real-time high fidelity expiratory CO2 analysis. The long-term goal is to detect pulmonary structural changes in a stage, when variables of currently used standard methods (e.g. pulmonary function test) are not yet altered.
