This pulmonary function test machine measures the human body’s expiratory function and inspiratory function through a respiratory flow transducer by employing an advanced micro-computer processing system. Then a liquid crystal display (LCD) displays the results and a graphic printer prints the printing results after analyzing and processing the measured results. Data and curves about the forced vital capacity, vital capacity, maximum voluntary ventilation, airway resistance, small airway conditions and the like of human body can be detected simultaneously, and the pulmonary dysfunction suffered by the subject is fully automatically analyzed.
 

Measurement parameters
1. Vital capacity measurement: VC, TV, ERV, IRV, IC, MV, RR
2. forced vital capacity measurement: FVC, FEV.1, FEV.2, FEV.3, PEF, V75, V50, V25, V50/V25, V25/H
3. Maximum voluntary ventilation measurement: MVV, BSA, MVV/BSA
4. Airway responsiveness experiment
