Pulse Spectrum Analysis in Adult Asthmatics: Correlation With Lung Function, Asthma Control Exhaled Nitric Oxide and Metabolites in Exhaled Breath Condensate
Pulse Spectrum Analysis in Adult Asthmatics: Correlation With Lung Function, Asthma Control Exhaled Nitric Oxide and Metabolites in Exhaled Breath Condensate
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.
The microcirculation is directly involved in the cellular matabolism and homeostasis. Our
 hypothesis is that radial arterial pulse spectrum may reflect the airway condition 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 lung function, asthma control
 status,exhaled nitric oxide, and metabolites in the exhaed breath condensates.
