Obstructive Airway Diseases Clinical Trial
Official title:
Nasal Muco-ciliary Clearance Study With and Without Salt Inhalation Via a Salt Particle Inhaler at COPD, Asthma and Healthy Individuals
Investigating nasal muco-ciliary clearance by scintigraphy
The velocity and the retention of the nasal muco-ciliary clearance is going to be investigated with a salt particle inhaler and a placebo by the method nasal scintigraphy. The hypotheses is that nasal inhalation of salt particles enhance the nasal mucociliary clearance. ;
