The American Thoracic Society (ATS) recently adopted a new set of 26 standard flow-time waveforms for use in testing both diagnostic and monitoring devices. Some of these waveforms have a higher frequency content than present in the ATS-24 standard v

In children, the ratio of forced expiratory volume in 1 s (FEV₁) to forced vital capacity (FVC) is reportedly constant or falls linearly with age, whereas the ratio of residual volume (RV) to total lung capacity (TLC) remains constant. This seems c

There are many potential problems with the use of serial peak expiratory flow (PEF) measurement to investigate potential occupational asthma. Among these are inaccurate and incomplete recording of results. However, PEF meters will continue to be used

Test reproducibility is an important consideration when interpreting results and should be set as a goal during data collection. Reproducibility criteria may need to be different for different subject groups and are instrument and procedure-dependent

Approximately half of a worker population may benefit from the addition of a longitudinal comparison of their spirometry results, over only using annual comparisons with a cross-sectional LLN. The ATS recommendation of 15% for year-to-year changes ap

In addition to improvements in spirometry instrumentation, the availability and quality of mechanical pump-testing equipment have also improved. These devices have largely relied on the ATS 24 standard waveforms and appear to simulate human FVC maneu

Acute spirometric responses to inhaled cotton dust were examined in a population of 226 healthy, non-asthmatic adults whose atopic status had been evaluated by skin prick tests to 10 common environmental allergens. Exposure to cotton dust occurred in

Thirty volunteer subjects were exposed to controlled amounts of respirable dust generated by the carding of cotton in an experimental cardroom. Eighteen exposures each lasting six hours were performed while carding unwashed and washed cottons from th

Measurement of persistence, expressed as half-life (t1/2), of a monodisperse aerosol during breath holding was interpreted as an indirect estimate of the size of intrapulmonary airspaces in healthy subjects. Within subject variation of t1/2 measured
