COMMON TROUBLESHOOTING DURING THERAPY
Pressing ‘patient care button’
Clamping the access/arterial line at patient access
Removing the red arterial pressure line from the pressure port on
the side of the machine only a small amount
Check to see if the blood has returned to the chamber from the
pressure line
Re-attach the red pressure line to the pressure port on the side
of the machine
Unclamp the access/arterial line at patient access
Take off patient care mode by pressing the ‘patient care’ button

This is due to stops in the blood pump/low blood flow causing a back flow of
blood from the arterial/access line. When blood is seen in the arterial pressure
line try and resolve this by:
BLOOD IN THE ARTERIAL (RED) PRESSURE LINE
As long as the blood pump is running this will cause the blood to move out
of the line and return to the chamber. If there is an arterial pressure alarm
during this procedure as a result of the access/arterial line being clamped
the blood pump will stop, ensure to reset the alarm to allow the blood
pump to run for enough time for the blood to be removed from the line and
continue as the steps detailed above. Ensure to always attach the pressure
line back on before unclamping the arterial/access line.
If the blood is already clotted in the pressure line DO NOT return it into
the machine, leave it as it is as you do not want to return clots to the
chamber. If blood reaches the pressure measurement sensor at the top of
the pressure line you may experience an arterial pressure measurement
failure alarm. Attempt to remove the blood if not clotted following the
steps above, and reset the alarm. If the alarm does not reset the kit may
require to be changed.
