Within-breath input impedance by impulse oscillometry in severely asthmatic horses

2018
Impulse oscillometry system (IOS) detects pulmonary obstruction in horses measuring average total respiratory system impedance (Zrs). In humans, analysis of within-breath changes of Zrs allows identification of the presence of expiratory flow limitation.
