ClinConnect Summary

This clinical trial is investigating a new inhalation therapy using ultrasound rock salt aerosol for patients with conditions like COPD (Chronic Obstructive Pulmonary Disease), asthma, and chronic bronchitis. The study aims to understand how well these tiny salt particles can reach the lungs when inhaled, comparing the effectiveness of this new method to a common device called a nebulizer. Researchers will use advanced imaging technology to track where these particles go in the lungs, helping to ensure that the new therapy could be beneficial for patients with respiratory issues.

To participate in this study, volunteers must be healthy or have chronic airway diseases that require nebulization therapy. However, individuals under 18 years old, those with certain health conditions (like severe liver or kidney problems), or anyone who is allergic to radioactive materials cannot join. Participants will inhale small amounts of these aerosol particles, and through imaging, researchers will study how they spread within the lungs. This research is important as it could help develop better treatments for people with breathing difficulties in the future.
