Ethnic Correction

While some predicted normal studies take into account the differences between certain ethnic groups,
most studies used for spirometry were conducted on Caucasian subjects, and are therefore most ap-
propriate for use with Caucasian patients. When entering patient information, you are presented with a
list of ethnic options. In the system configuration there are four Ethnic Correction settings that allow
you to customize the amount of adjustment that is made when African-American, Hispanic, Asian, or
other is chosen during patient data entry. The adjustment is made to the Caucasian values.
There is an exception to this function. When specific values are available for the chosen normal and
ethnic group they will be used rather than the correction entered in the configuration. Refer to Section 8
for instructions on setting the Ethnic Correction Configuration.
The American Thoracic Society s publication, Lung Function Testing: Selection of Reference Values and
Interpretative Strategies [8] provide guidance on the subject of ethnic correction. This paper recom-
mends using 88% of the Caucasian values when testing African-American patients, and provides gen-
eral guidance in selecting adjustments for other ethnic groups.
