Reference Value Equations
ECCS/Zapletal
This equation uses reference values developed by QUANJER (ECCS93)
and ZAPLETAL.
The ECCS reference values were published 1993 (ISBN 87-16-15024-4).
The reference values are height and gender-related and are defined for
patients aged 19 to 70 years.
Note
Patients between 19 and 25 years of age are assumed to be 25.
A range for height is not defined.
The ZAPLETAL reference values were published 1987. (Progress of
Respiration Research Vol 22 (1987): Lung function in Children and
Adolescents; ISBN: 3-8055-4495-2).
The reference values are height and gender-related and are defined for
patients aged 5 to 18 years.
Note
Height range from 107 cm to 182 cm.
For patients exceeding the range limits, the limit values will be
used.
The equation defines the following reference values: FEV1/FVC
(calculated from single values), FEV1, FVC, MEF25, MEF50, MEF75,
MMEF, PEF, VC (same as FIVC).
NHANESIII
This reference value equation was published 1999 (AM J RESPIR CRIT
CARE MED 1999; 159:179-187).
The reference values are height and gender-related and are defined for
patients aged 8 to 80 years from the ethnic groups Caucasian (Race
selection: Caucasian), African American (Race selection: Black), Mexican
