Exercise-induced bronchoconstriction (EIB) and Exercise-induced asthma (EIA) are used synonymously to describe acute lung airway narrowing occurring during and/or after exercise. Tools usually used by health practitioners to assess the severity of EIB or EIA symptoms include bronchodilator tests and various bronchial provocation procedures including spirometer and eucapnic voluntary hyperpnoea (EVH) challenge system, there is no tool that is able to monitor the severity of acute lung airway narrowing. This study aims to design a graphical user interface (GUI) to monitor the severity of acute lung airway narrowing using MATLAB software. The GUI will present the measurement data into a simple and user-friendly program consisting of patient information, EVH test analysis and detection of EIA and EIB. Success of this project widens the usage of EVH challenge in medical areas and the GUI may serve as a new clinical computer-aided diagnostic tool to help healthcare professionals non-invasively monitor the severity of asthma, EIA and EIB.
