Ethnic correction

Some studies for predicted values take into account the differences between

certain ethnic groups. However, most studies that are used for spirometry

were conducted on Caucasian subjects and are therefore most appropriate for

use with Caucasian patients.

When entering patient information, you are presented with a list of options for

four ethnic groups. In this setting, you can define the corrections for these

ethnic groups. The adjustment is made to the values for Caucasian patients.

There is an exception to this function. If specific values are available for the

chosen group of predicted values and the chosen ethnic group, they will be

used instead of the correction entered here.

The American Thoracic Society’s publication, Lung Function Testing: Selection

of Reference Values and Interpretative Strategies [8], provides guidance on

the subject of ethnic correction. This paper recommends using 88% of the

Caucasian values when testing African patients and provides general

guidance in selecting adjustments for other ethnic groups.
