Glossary
adult. Generally, 18 or older. Age limits vary with each norm.
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
ATS interpretive results. The software generates interpretive results as described in the document noted
in
baseline. See
.
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
.
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 are 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, four curve types are available: volume/time, flow /volume, tidal volume, and
(on screen only) incentive.
