    Automated spirometry uses quantitative criteria for test acceptability, but these minimum standards may not catch all quality issues. Visual inspection of spirometric curves remains crucial for accurate pulmonary function testing.

    Area of Science:

    • Pulmonary Medicine
    • Medical Device Technology

    Background:

    • Automated spirometers utilize quantitative criteria to assess spirometric tracing acceptability.
    • These criteria are programmed into devices to aid in data collection and quality assurance.

    Purpose of the Study:

    • To evaluate the adequacy of current quantitative test criteria for spirometry.
    • To highlight potential limitations of automated quality assessments in pulmonary function testing.

    Main Methods:

    • Review of spirometric tracings that met automated quantitative criteria.
    • Comparison of automated assessments with visual inspection of curve quality.

    Main Results:

    • Automated spirometers may indicate 'tests meet acceptability criteria' even when tracings have visible defects.

  • Quantitative criteria, while useful, may not identify all unacceptable spirometric maneuvers.
  • Reliance on automated statements can lead to acceptance of suboptimal test results.

    • Conclusions:

    • Quantitative spirometry criteria serve as minimum standards and should not replace visual inspection.
    • Thorough review of all spirometric curves is essential for ensuring data integrity, particularly in longitudinal studies.
    • Medical professionals should be aware of the limitations of automated spirometry quality checks.
