8 EtCO
2
values are
consistently higher than
expected.
Physiological cause such as
COPD.
None.
Inadequate ventilation. Check ventilator; increase
ventilatory rate/bagging.
Patient splinting during
breathing.
Supporting measures such
as pain relief.
Improper calibration. Contact qualified service
personnel.
9 EtCO
2
values are
consistently lower than
expected.
FilterLine connection to device
is loose.
Twist FilterLine connector
clockwise until firmly seated
and can no longer be
turned.
Physiological cause. See Physiological factors in
"CO
2
Detection," page 3-21.
Hyperventilation. Check ventilator; decrease
ventilatory rate/bagging.
Improper calibration. Contact qualified service
personnel.
10 CO
2
waveform stays
elevated for several
seconds.
Expiration is prolonged due to
bagging technique.
Release bag reservoir
completely with expiration.
Observe that elevated
baseline returns to normal
level.
11 Sudden extreme increase in
EtCO
2
.
Fluid has entered CO
2
module. Contact qualified service
personnel.
12
CHECK CO2 message
appears.
FilterLine blockage Disconnect and then
reconnect the FilterLine set.
Change the FilterLine set.
Exhaust port blockage Ensure exhaust port on the
back of the device is not
blocked.
Check exhaust tubing (if
present) for blockages or
kinks.
RF equipment too close to
defibrillator
Separate RF equipment
from defibrillator. See
recommended separation
distances in Table 4, page
H-4.
13
XXX appears instead of
EtCO
2
value.
CO
2
module malfunction. Turn device off and then on
again.
If problem persists, contact
qualified service personnel.
14 There is no EtCO
2
value
and the CO
2
waveform is
flat.
Measured CO
2
is less than
3.5 mmHg.
