At the end of the manoeuvre, one or more of the Warnings, if
enabled in the Customisation Programme, may appear to warn
whether the manoeuvre is compliant with ATS/ERS Criteria.
According to the indication, the manoeuvre has not been carried
out according to one of the following ATS/ERS criteria:
ET - Indicates that spiration has not completed satisfactorily, as
the variation on volume in the last second of the manoeuvre was
above 25 ml, or the manoeuvre has lasted less than 6 seconds
(in patients aged over 10 and more) or less than 3 seconds (in
patients aged 10 or less).
EX - Indicates that the start of expiration was not satisfactory, as
the extrapolated volume is above 5% of the FVC or 0.15 litres.
The ATS/ERS recommends it be less than 5% of the FVC or 0.15
litres, whichever is highest.
The technician performing the spirometry may, where
considered appropriate, disable these warnings in the
Customisation Programme. In this case, they will also be
removed from the printed report.
This disabling is only at display level. The warnings are
still taken into account when ordering the manoeuvres.
ATTENTION: Check in the Customisation Programme that
the REFERENCES and the ETHNIC FACTOR are suitably
selected. The ethnic factor modifies the value of the
References according to the percentage selected. 100%
is equivalent to the unmodified standard value of the
References.
