In the case of ATS/ERS standards: depending on the ethnic group set, the correction
percentage acts on the predicted values of the following parameters:
FVC, FEV1, FEV3, FEV6, FIVC, FIV1, EVC, IC, VC, ERV, TV, TV/ti
In the case of NHANES III standards: depending on the ethnic group set, different
predicted formulae are taken into account (in accordance with the reference standard).
Once the desired ethnic group has been selected, the device completes defining the patient
parameters and returns automatically to the main screen.
In the case of GLI for every Ethnic group the device applies a different table to calculate
the predicted values and not a correction percentage.

Editing patient data
Select the icon and use the screen as described in section 2.6.1.
WARNING
Selecting this function does not create a new patient as described beforehand, but
changes the data of the same patient and associates future test data with that
patient, who is always identified with the same unique ID code.
