OSHA-NIOSH Info Sheet: Maximize Your Spirometry Screening and Surveillance Resources
DHHS (NIOSH) Publication Number 2011-133
Spirometry is a common type of pulmonary function test (PFT) that measures how well a person can move air in and out of their lungs. In occupational settings, spirometry can be used to establish a baseline before assigning a worker to job tasks that are physically demanding, that require use of a respirator, or that may expose the worker to respiratory hazards. It is also used to track lung function over time and to evaluate workers who experience signs or symptoms of respiratory disease.
