Implication

Bench evaluation demonstrates compliance with standardized accuracy criteria across commercial spirometers, indicating that certified devices yield interchangeable lung function results.

Key Points

Determine the performance characteristics of commercial spirometers against American Thoracic Society standards and evaluate whether accuracy testing can be conducted using room air.
Tested 19 commercially available spirometer models using 16 distinct standard forced vital capacity waveforms.
Evaluated device performance for forced vital capacity, forced expiratory volume in one second, and maximal voluntary ventilation under ambient room air versus heated and humidified air.
Fourteen of 19 spirometers met American Thoracic Society standards for forced vital capacity and forced expiratory volume in one second, though 3 of these 14 had difficulty detecting the end of expiration.
Ten of 13 evaluated devices performed satisfactorily during maximal voluntary ventilation assessments.
Testing with room air proved as effective as heated and humidified air across most devices while simplifying the testing procedure.
