When two manoeuvres fail either of the consistency checks, then the
best individual results of the two are saved (FEV1, FEV6, and PEF
individually).
When any of the above messages appear, instruct the patient on
how to improve their manoeuvre and demonstrate the correct
manoeuvre yourself.

NLHEP Interpretation

The interpretation is performed on the best spirometry results and is
based upon the predicted values for the forced expiratory ratio,
FEV1/FEV6, and FEV1. If airways obstruction is detected the level of
severity is reported in accordance with the NLHEP guidelines.
