NCT01719393

Brief Summary

Our hypothesis is that radial arterial pulse may reflect the severity and airway function in asthmatics. The aims of this study are to investigate the pulse spectrim of the radial artery in adult asthmatics, and evaluate its correlation with airy inflammation an lung funtion in asthmatics.
