STELLANT PRESSURE MONITOR HELFUL HINTS – 203473 Rev. A.
CONDITION# DESCRIPTION POSSIBLE CAUSES POSSIBLE ACTIONS
Condition #1 The graph is the typical
shape, but the pressure
is higher than normal.
The pressure required to push
the contrast media through
the disposable system is
higher than normal, which
means there is a greater
restriction to fluid flow.
Greater restriction can be
caused by any of the
following:
* Higher viscosity of the
contrast media
(more grams of
iodine/higher
concentration, or lower
temperature of
of the contrast media/not
heated.
* A smaller gauge catheter is
being used.
* An additional disposable is
in the fluid
path causing a greater
restriction to the
flow of fluid (extension
tube, stopcock,
check valve, IV extension
set).
* Defective syringe (under
lubricated).
Check to insure the syringe
heater is functioning
normally. As long as the
“Possible Causes” listed are
of no concern, then no
action is necessary.
Condition #2 The graph is the typical
shape, but the pressure
is lower than normal
The pressure required to push
the contrast through the
disposable system is lower
than normal, meaning there is
less restriction to fluid flow.
Lower restrictions can be
caused by any of the
following:
* A lower visocity contrast
media (less
grams of iodine/lower
concentration,
or higher temperature of
As long as the “Possible
Causes” listed are of no
concern, then no action is
necessary.
