    Summary
    This summary is machine-generated.

    Spirometer performance control is crucial, as 55% of devices failed technical tests. Regular maintenance and early detection of manufacturing issues are vital for accurate respiratory function measurements.

    Area of Science:

    • Pulmonary Function Testing
    • Medical Device Performance Evaluation

    Background:

    • Spirometers are essential for diagnosing respiratory diseases.
    • Ensuring accurate spirometer performance is critical for reliable clinical data.

    Purpose of the Study:

    • To assess the performance of spirometers in a clinical setting.
    • To identify factors affecting spirometer accuracy and reliability.

    Main Methods:

    • Evaluated 27 spirometers using 11 technical parameters.
    • Calculated figures of merit (FM) based on weighted test results.

    Main Results:

    • 55% of the tested spirometers failed to meet performance standards.
    • Performance varied by instrument, was maintenance-dependent, and age-independent.

  • Accuracy issues were noted with wedge-type volume meters.

    • Conclusions:

    • Routine performance testing and maintenance are essential for spirometers.
    • Early detection of manufacturing defects through acceptance trials is recommended.
    • Daily calibration alone is insufficient for maintaining optimal spirometer performance.
