PinYuan LUD-V2 portable pulmonary function tester specification
The pulmonary function tester we developed and produced use the most advanced differential pressure flow sensor to obtain the measured results, through three measurement methods (slow vital capacity (SVC), forced vital capacity (FVC), and voluntary ventilation (MVV)) to get the user's expiratory flow signal , then calculated and evaluated to provide scientific basis for early screening and diagnosis of respiratory diseases such as chronic obstructive pulmonary disease (COPD), emphysema, asthma, etc. This measurement method is more accurate and efficient. More practical.
Product Parameters
1. Measurement method: differential pressure flow test method
2. Sensor: High precision double differential pressure flow sensor
3. Flow measurement range: 0L/s ~ ±14L/s
4. Flow measurement error: The maximum allowable flow error in the measurement range should be: ±10L/min (±0.17L/s) or ±5% of the reading
5. Volume measurement range: 0-8 L volume measurement error: ±3% or ±0.050L, whichever is the maximum
6. Airflow resistance: The airflow resistance within the test range should not exceed 0.35KPa/ (L/s)
7. Frequency response: no more than 0.25L/s or 12%
8. Linearity: the difference of the average error of two adjacent test flows does not exceed 5% of the two test flows, and the test flow change does not exceed 0.17L/S or 5% of the reading
9. Pulmonary function measurement: forced vital capacity (FVC), slow vital capacity (SVC), and voluntary ventilation (MVV) can be measured.
10. Lung function measurements were guided by animation.
