5.4.3 Gas Exchange
The messages below appear in the gas exchange parameter windows (PW).
Scale changed WF Displayed for 10 seconds after
autoscaling mode has changed Flow,
Paw, or Vol scale. N/A
Saving loop MF Spirometry loop is being saved. N/A
Printing loop MF Spirometry loop is being printed. N/A

removed MF The module is disconnected. Reconnect the module.
Message Location Possible causes Possible solutions
No VO2, FiO2>85%
PW Unable to measure gas VO
2
because the measured FiO
2
is
out of gas exchange
specification (>85%).
Use lower O
2
concentrations.
No VO2, FiN2O too high PW Unable to measure gas VO
2
because the measured FiO
2
+
FiN
2
O is out of gas exchange
specification (>85%).
Use lower O
2
concentrations.
Artifact PW Module is unable to synchronize
flow and CO
2
.
Use a 2 meter gas sampling tube
and spirometry tube with gas
exchange.
Bypass flow high PW Module is unable to synchronize
flow and CO
2
due to bypass flow.
Reduce fresh gas flow.
Out of range PW VO
2
or VCO
2
is <0 or >999 ml/min
and thus out of measurement
range.
After changing the FiO2 setting
on the ventilator, VO2 may be
out of the specified range for
several minutes.
Check that the gas sampling line
and spirometry lines are
correctly connected to the
airway and to the gas module.
Check that the correct sensor
type (D-lite/ Pedi Lite) has been
selected from the monitor menu.
