    A new bellows spirometer was assessed against a water spirograph. It demonstrated slight non-linearity but is suitable for large-scale field surveys due to its portability and low cost.

    Area of Science:

    • Pulmonary Function Testing
    • Medical Device Evaluation

    Background:

    • Spirometry is crucial for diagnosing respiratory diseases.
    • Accurate and portable spirometers are needed for widespread clinical use and field surveys.

    Purpose of the Study:

    • To evaluate the accuracy and suitability of a new bellows spirometer.
    • To compare its performance against a standard water spirograph.

    Main Methods:

    • Comparative analysis of a novel bellows spirometer and a traditional water spirograph.
    • Assessment of linearity and key spirometry parameters: FVC and FEV1.

    Main Results:

    • The bellows spirometer showed slight non-linearity.
    • Minimal overestimation of Forced Vital Capacity (FVC) by 1.7%.

  • Slight underestimation of Forced Expiratory Volume in 1 second (FEV1) by 2.9% and FEV1/FVC ratio by 4.8%.

    • Conclusions:

    • The bellows spirometer offers advantages in lightness, ease of use, ruggedness, and cost.
    • It is well-suited for large-scale field surveys and general clinical applications.
