12.3 Norm Extrapolation
Extrapolation is the practice of applying a norm’s formula to a patient whose profile doesn’t fit
that norm’s profile. For example, if you were testing an 88-year-old man, and the primary
(selected) norm was based on males 85 or younger, the predicted values are extrapolated
values.

When it takes place, extrapolation is indicated in the test record.

Pediatric norms do not provide any age, weight, or height extrapolation.

Adult norms allow extrapolation of age up, but not down.

Adult norms allow extrapolation of height, weight, up and down.
12.4 Composite Norm Values
When the Composite norm, see tables in section 12.1, is selected, predictive parameter
values are filled in from one of the alternative (composite) norm sources listed here.
NHANESIII FVC, FEV1, FEV1%, FEV6, FEV1/FEV6, FEV6/FVC, PEF,
FEF25-75
Crapo 1981 FEV0.5, FEV3, FEV3/FVC
Morris 1971 FEF0.2-1.2
ECCS/Quanjer 1993 FEF25, FEF50, FEF75
Note: If an adult norm is selected but pediatric patient data is used
– no prediction value
will be calculated and displayed.
The following combinations of norms are supported:
