Lung Function Clinical Trial
Official title:
Maximal Effort-dependent Respiratory Flow Rates: Reproducibility and Reference Values
The general objective of this project is to determine the best method to measure maximal inspiratory flow rates, to study their reproducibility and create reference equations in healthy subjects.
