Quality Messages and Quality Grades
Low Inspiratory Vol-
ume
Maneuver not
acceptable. Inspira-
tory volume too low
The inspiratory volume is smaller
than 85% FVC/VC/Predicted
Make sure to perform a full expira-
tion before the valve closes, and
then a full inhalation of test gas
Inspiratory Time Too
Long
Maneuver not
acceptable. Inspira-
tion time exceeds
the maximum of 4
seconds
Inspiratory time > 4 seconds
Inhale test gas faster
Sampling volume at
this position too
large
Sample volume not correctly
determined
Reduce sample volume
Difference Prepara-
tion and Maneuver
Test cannot be evalu-
ated; gas sensor sig-
nals do not pass QC
check, possibly due
to leaks
Reference gas measurement and
inspiratory gas measurements do
not match within 80 ppm. This
means that most probably there is
a leak in the DLCO hose
Check for leaks; check gas supply
Sampling volume at
maximum position
Test cannot be evalu-
ated; exhaled vol-
ume too small
Can happen when very small vol-
umes are exhaled
Collection bar is beyond rightmost
position
Activate „Automatically rejected
volume“
After the breath hold, do not
exhale too fast.
DLCO-Warning: High
inspiratory CO dur-
ing tidal breathing!
An increased CO level was
detected during the tidal breath-
ing phase.
Check the DLCO valve unit.
If the error occurs repeatedly then
please contact service.
Test error: # of
breaths
Test cannot be evalu-
ated; DLCO maneu-
ver cannot be
detected
Number of breaths during DLCO
expiration could not be detected
Perform the DLCO maneuver with
full effort
