STATUS M ESSAGES
VF8 DELTA/DELTA XL/KAPPA 15-15
C.O. No
Temperature
Change
The detected temperature change was
< 0.1 °C, because of the following
conditions:
• C.O. START was pressed but no
injection was made
• The injectate volume was too small
• Defective catheter
• The injectate temperature was too
warm.
• Repeat the measurement.
• Use a larger injectate volume.
• Repeat the measurement. If
problem persists, replace the
catheter.
• Use colder injectate.
C.O. Use Cooler
Injectate
• < 5 °C difference exists between
patient's blood temperature and the
injectate temperature.
• Injectate temperature of greater than
30°C.
Use a cooler injectate.
C.O. Injectate Set to
<IT value>!
C.O. START was pressed, but no
injectate probe is connected.
Connect injectate probe.
C.O. Average Saved The C.O. average has been saved. None required.
C.O. Transducer
Unplugged
A cable or transducer has become
disconnected.
Reconnect the cable or transducer.
If message persists, replace
defective part.
C.O. Poor Baseline The temperature curve did not return
to baseline within 30 seconds of
pressing C.O. START because of the
following conditions:
• Unstable patient temperature
• Defective catheter, cable, or
cartridge
• Follow hospital procedures.
• Repeat the measurement. If
message persists, replace the
defective components.
C.O. Pod Fault -
Bad Ref.
The pod reference resistance is either
too high or too low.
Remove and reconnect the pod.
Repeat the measurement. If
message persists, replace the pod
and contact DrägerService.
C.O. Catheter Fault
- Bad Ref.
• The catheter reference resistance is
too low.
• Unknown catheter type.
• Check the catheter and replace if
defective.
• Contact the hospital’s technical
personnel or DrägerService.
C.O. Check
Injectate Probe
the injectate temperature probe is not
connected or was disconnected during
a measurement.
Connect the probe and repeat the
measurement.
