The results for simulated airway restriction are shown at figure and table 3. Airway restriction prevents air from diffusing into pulmonary arteries as a kind of blockage in the lungs. Based on the data, peak inspiratory flow, peak expiratory flow, forced vital capacity, forced expired volume in one second, and the ratio FEV1/FVC are affected by the simulated restricted airflow. Peak respiratory flow, peak expiratory flow, and forced expired volume in one second have lower values in the restricted airway. The forced vital capacity is higher in the restricted airway simulation. The ratio FEV1/FVC which is 76% in an unrestricted airway dropped to 30% in the restricted airway simulation. This means that restricted airway is often accompanied by
