Effect of Ipratropium Bromide on EILO

The investigators propose a study that compares breathlessness and airway obstruction during intense exercise in 34 children and adolescents with Exercise-Induced Laryngeal Obstruction after breathing in ipratropium bromide or placebo. It is hypothesized that breathlessness and airway obstruction will be lower following breathing in ipratropium bromide compared with placebo.

Effect of Neuromuscular Electrical Stimulation of Lower Limbs on Improving Exercise Self-Efficacy, Dyspnea During Activity and Fatigue in Patients With Chronic Obstructive Pulmonary Disease

Patients diagnosed with COPD who meet the inclusion and exclusion criteria, either inpatients or outpatients, will be informed about the study'sstudy's purpose and procedures by the principal investigator. After understanding their rights, they will provide informed consent.

SWEEP: Shuttle Walking Test for Exercise Evaluation in Pulmonary Resection

This is a prospective observational study that evaluates whether the Shuttle Walking Test (SWT) can predict postoperative symptoms, particularly dyspnea, in patients with chronic respiratory diseases undergoing lung resection. Currently, tools such as DLCO or cardiopulmonary exercise testing (CPET) are used to assess surgical risk and exercise capacity before lung surgery. However, these tests are not always accessible due to equipment limitations or long waiting times. The SWT is a simpler, safer, and more cost-effective alternative that has been recently recognized as a new medical technology in Korea for evaluating exercise capacity. In this study, patients with chronic lung diseases (such as COPD, ILD, or bronchiectasis) who are scheduled to undergo lung resection will perform the SWT before surgery. Their symptoms and quality of life will be assessed through questionnaires before and three months after the surgery. The goal is to determine whether SWT results can help predict postoperative dyspnea and provide useful information for preoperative risk stratification.
