Breathing Test Lung

Product Parameters of the PinYuan LUD-V1

1. Method of measurement: differential pressure flow test2. Sensor: High-precision double differential pressure flow sensor3. Flow measurement range: 0L/s to ±14L/s4. Flow measurement error: The maximum allowable flow error in the measurement range is ±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 highest

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 test flow change does not exceed 0.17L/S or 5% of the reading, and the average error of two adjacent test flows does not exceed 5% of the two test flows.9. Pulmonary function measurement: voluntary ventilation (MVV), forced vital capacity (FVC), and slow vital capacity (SVC) can be assessed.10. Animation was employed to guide lung function measurements.11, Measurement parameters: FVC, FEV0.5, FEV1, FEV3, FEV1/FVC, PEF, MEF75, MEF50, MEF25, MMF, OI, FIVC, PIF, and FIV1; VC, TV, ERV, IRV, IC, VC/HT; MVV, RR, MVV/BSA, TV, and BSA.

12. The pulmonary function measurement results were used to generate the volume-flow velocity curve and time-volume curve.

13. A distinctive filter and mouth design that ensures greater tightness and prevents air leakage during the measurement process.

14. It is capable of evaluating ventilation defects and COPD.

15. System software functions: instrument zero and calibration, doctor management system, history review system, medical record review function, and user file management function.
