- Airway resistance [ Time Frame: one minute ]The indices of Airway resistance include total respiratory impedance (Zrs).
- forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC, and maximum midexpiratory flow (MMEF). [ Time Frame: one minute ]The indices of spirometry include forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FEV1/FVC, and maximum midexpiratory flow (MMEF).
