12 Monitoring Cardiac Output

C.O./CCO Safety Information
WARNING
Catheter constant - Make sure that the arterial catheter constant for the measurement is appropriate
to the catheter used.
Computation Constant - Make sure that the computation constant for the measurement is
appropriate to the injectate volume, injectate temperature and catheter type used.
IABP - Do not perform transpulmonary thermodilution measurements on patients undergoing IABP
treatment.
CCO accuracy - Accuracy of the CCO measurement and all the derived values may be influenced by
patients with valve diseases or artificial valves.
C.O. and MRI - Do not use the Cardiac Output Interface Cable in Magnetic Resonance Imaging
(MRI) Applications.
Aortic graft patients - Do not use an arterial catheter in the arteria femoralis when it is contra
indicated, for example, with patients who have an aortic graft.
C.O./CCO Warning Messages Possible Causes
Next measurement erases older
curve
Six curves are stored, this is the maximum possible. If
another measurement is stored, the oldest thermodilution
curve will be erased.
Previous C.O. setup data replaced A C.O. module or measurement extension module has
been plugged in with different C.O. setup data from the
previous data. The new C.O. setup data is read from the
new C.O. device, and replaces the current data. The
message disappears when the Start C.O. pop-up key is
pressed.
Verify C.O. setup data A new transpulmonary thermodilution catheter has been
connected to the C.O. Interface Cable.
Check arterial pressure, CCO cal
currently not possible
Poor or invalid pressure signal, for example if pressure
was not zeroed.
Verify the Computation Constant A new catheter has been plugged in, or the computation
constant has been changed and
Start C.O. has not been
selected.
Previous Comp. Constant
replaced
A new C.O. module or measurement extension module
with a different computation constant from the current
one has been connected. The new computation constant
is read from the new C.O. device, and replaces the
current one. The message disappears when
Start C.O. is
selected.
