Measurement of Respiratory Admittance for Pediatric Asthma Diagnosis (SALBUTAMOL)

August 19, 2016 updated by: Central Hospital, Nancy, France

Measurements of Change of Respiratory Admittance Induced by Salbutamol for Pediatric Asthma Diagnosis

The purpose is to characterize the change of respiratory admittance induced by salbutamol inhalation in children and young adults. A variation threshold will be fixed to distinguish asthmatic and healthy subjects.

This project could allow a better identification of asthmatic individuals needing a treatment, a reduction of morbidity of asthma, a reduction of unnecessary treatments administered in individuals with respiratory but not asthmatic symptoms, a better comprehension of bronchial hyperreactivity and its role in asthmatic disease.
