C.O./CCO Curve Alert
Messages
Check Injectate Temperature
Probe Type
Unsteady baseline
Multiple peaks
Abnormal decay time
Very long curve
Very short curve
Irregular curve
Delayed injection
If you have followed all of these guidelines, your measurement values should be valid, even if you still
see a curve alert message. Ensure that at least three subsequent measurements within the current series
do no differ by more than 15%. If the difference exceeds 15%, use your clinical judgment to determine
the appropriate intervention.

C.O./CCO Prompt Messages

Prompt messages appear in the procedure window if a C.O. measurement trial must be terminated.
C.O./CCO Prompt Messages
Curve below baseline,
measurement terminated
Excessive curve height,
measurement terminated
Unstable baseline, injection not
recommended!
Excessive baseline drift, don't
inject now!

C.O./CCO Warning Messages

Warning messages contain important information about the C.O. measurement.
Possible Causes
The recorded Tinj signal is uncharacteristic for the M1646
injectate temperature probe. An incorrect probe type may have
been used.
There is a noisy baseline, and thermal baseline drift.
Caused by faulty injection technique.
May be caused by low cardiac output. Calculated value for
C.O. may not be accurate.
The decay time of the curve is longer than 15 seconds.
Decay time of the curve is less than 0.5 seconds. If there is a noisy
baseline, part of the baseline may have been mistaken for a
thermodilution curve. Calculated value for C.O. may not be
accurate.
Any combination of curve alert messages.
Injection is given more than 15 seconds after
selected. Calculated value for C.O. may not be accurate.
Possible Causes
May be caused by thermal baseline drift. No C.O. value
calculated.
The curve exceeds the upper limit. This may be caused by an
injectate that was too cold. No C.O. value calculated.
The baseline is unstable. Wait until the baseline is stable before
injecting. If this does not occur within a reasonable time,
injection is possible but the accuracy of the measured values
may be reduced.
No measurement is possible. Measured values are incorrect.
