The Centers for Disease Control and Prevention released a video tutorial demonstrating how to perform calibration checks to verify spirometry system accuracy [1].
Accurate calibration is critical for health professionals to ensure that lung function tests are administered according to standard professional practice guidelines. Incorrectly calibrated equipment can lead to diagnostic errors in patients with respiratory conditions.
The tutorial is part of a larger seven-video series [2] designed to educate medical practitioners on the proper administration of spirometry testing. The specific guide focuses on the verification process to maintain the integrity of the data collected during patient exams.
According to the CDC/NIOSH video description, the goal is for users to "learn how to perform calibration checks in spirometers" [3]. The instructional content is associated with NIOSH publication number 2017-167 [4].
This educational resource was first published in July 2017 [1] on the agency's YouTube channel. By providing a visual step-by-step process, the National Institute for Occupational Safety and Health aims to standardize the way technicians verify their equipment across different clinical settings.
Health professionals are encouraged to follow these calibration protocols to minimize variability in test results. The series serves as a technical reference for those operating spirometers in occupational and clinical health environments.
“Learn how to perform calibration checks in spirometers.”
The availability of standardized, government-backed calibration tutorials reduces the risk of diagnostic variability in respiratory medicine. By anchoring clinical practice to a specific NIOSH publication, the CDC ensures that health professionals across the U.S. use a uniform methodology to verify equipment accuracy, which is essential for the longitudinal tracking of chronic lung diseases.
