This prospective observational clinical study investigates two key questions in COPD patients undergoing sedated endoscopic procedures. The first is whether respiratory deterioration that may occur during the procedure is associated with clinical risk indicators such as symptom burden, prior exacerbations, and previous hospitalizations. The second is to assess the effectiveness of the Integrated Pulmonary Index (IPI) in predicting this deterioration, and to compare its performance with traditional respiratory monitoring parameters including oxygen saturation (SpOâ‚‚) and capnography (EtCOâ‚‚). The study hypothesis is that respiratory deterioration is linked to clinical risk indicators and that the IPI will demonstrate superior predictive accuracy compared with classical monitoring parameters. All participants will belong to a single COPD cohort and will not be assigned to different intervention arms. For analysis, patients will be categorized based on whether clinical interventions-such as increased oxygen flow, repositioning, or respiratory support-become necessary during the procedure. This classification reflects routine clinical care, and no additional interventions are performed as part of the study.
