PROBLEM
POSSIBLE CAUSE
SOLUTION
The test was performed
wrongly
Repeat the test, following the directions
displayed on the screen. Avoid sudden
movements when you finish exhaling
The turbine has not been
inserted properly
Insert the turbine from the front of the
device by pushing it all the way down
and turning it clockwise. See the
Performing the test
section
The oximetry test has
not been stored
The test lasted less than 30
seconds or the average value
of the finger pressure was
unsatisfactory
Repeat
the
test
following
the
instructions given on the display and
wait at least 30 seconds for the test to
complete.

ACCURACY AND RELIABILITY
This device meets the requirements of the following standard:
ATS/ERS TASK FORCE: Standardization of lung function testing (volume 26/numbers 1-5: 2005)
Volume max
10 I
Volume accuracy: the higher value between
2.5% and
0.05 l (ATS 2019)
Max. peak flow
960 l/min (16 l/s)
Peak flow accuracy: higher value between
10% and
20 l/min (
0.33 l/s)
Time zero
At the point of peak expiratory flow (PEF), a tangent
is drawn with a slope equal to PEF and its
intersection on the abscissa defines TIME ZERO. The
back extrapolated volume is the volume of gas that
has already been exhaled at the point of TIME ZERO
as defined by back extrapolation. The method to
determine the time elapsed by TIME ZERO, t0, is
given by the following equation:
