20 Glossary
adult. Generally, 18 or older. Age limits vary with each norm.
ASS. American Security Society.
ATS. American Thoracic Society. An organization that provides standards for spirometry
common practice and equipment.
ATS acceptability criteria. Applicable to FVC testing only. (1) Criteria ensuring that an
individual effort started and ended satisfactorily (no leaks or coughs). (2) Criteria ensuring
that the patient has made at least two efforts of the same kind (two FVC-pre or two FVC-post),
and that these efforts are reproducible. For details, see document noted in reference 5.
ATS interpretive results. The software calculates interpretive results as described in the
document noted in reference 2.
baseline. See pre-test.
best effort. A measurement calculated from a set of efforts. The formula for calculating best
effort is user-selectable: (1) the single best effort or (2) a composite of best parameter values.
BF. Breathing frequency. See also MV and tidal breathing.
bronchospasm evaluation. See post-test.
BTPS. Body conditions, normal body temperature (37° C), ambient pressure, saturated with
water vapor. The BTPS correction factor converts ambient conditions
—temperature,
humidity, and pressure — to BTPS.
CardioPerfect workstation. A PC using Welch Allyn CardioPerfect software. Stores ECG
and spirometry test data. Can communicate with other electronic patient-information
systems, such as billing and medical records.
composite norm value. A value that is filled in from another norm
—a “composite norm
source”—when the primary (selected) norm does not support a given parameter. Applicable
only when “composite norm values” is enabled.
COPD. Chronic obstructive pulmonary disease. Characterized by airflow obstruction that is
primarily caused by smoking. Examples include emphysema, chronic bronchitis, and
asthmatic bronchitis.
curve. A graphical display of spirometry data. During SVC testing, only one curve type is
available: volume/ time. During FVC testing, three curve types are available: volume/time,
flow/volume, and flow/time.
effort. A single spirometry maneuver, for example, one blow. A test typically comprises
multiple efforts. See also best effort and test.
ERS. European Respiratory Society.
ERV. Expiratory reserve volume (in liters). The maximum volume that can be expired from the
level of the functional residual capacity (FRC). See also tidal breathing.
extrapolation.
The practice of applying a norm’s formula to a patient who doesn’t fit that
norm’s demographics. For example, if you were testing an 88-year-old man, and the primary
