alarm limits using the Keypad . See "Arterial Pressure Button" and
"Venous Pressure Button" in chapter 3 for instructions on manual
setting of the alarm limits.
The alarm windows will automatically be widened and the buttons
start to fl ash when the blood fl ow rate is changed or when the
Blood Pump button is pressed.
Upon request from the clinic, an authorized technician can preset the
high arterial pressure alarm limit
to a fi xed value. This is to facilitate
pre-blood pump infusions during treatment during certain conditions,
see “Infusions during Treatment” page 3:36, part 1 for instructions.
Note that the function of the high arterial pressure alarm limit is in
this case deactivated implying that the operator is responsible for
monitoring the arterial pressure during treatment.
WARNING
When the high arterial pressure alarm limit is preset to a fixed
value
or when the arterial pressure measurement function is
not used, there is a risk for air-embolism if the arterial access is
accidentally disconnected. This is especially so when using the
machine in combination with a central venous catheter (due to
possible negative pressure in the catheter).
WARNING
TMP
When the
TRANSMEMBRANE PRESSURE CONFIRM MENU
is
displayed on the Information Display, press the Select key to con fi rm
the settings i.e. that the current TMP value and the automatically set
TMP alarm limits are set in accordance with the current UF rate and the
UF coef fi cient of the dialyzer being used. If the TMP alarm limits have
not been con fi rmed within two minutes, an attention appears where the
operator is requested to con fi rm the current settings.
If necessary the TMP alarm limits can be manually set/adjusted within
the preset alarm window by fi rst pressing the Fluid Path button ,
selecting TMP, and adjusting the alarm limits using the Keypad . For
instructions on manual setting of the alarm limits, see "Fluid Path
button" in chapter 3. Go to "Transmembrane Pressure" last in the list.
The TMP alarm window will automatically be widened when the
UF Start/Stop button is pressed.
CAUTION
When negative TMP alarm limits are set, the operator will not be
notified via alarm or attention alarm
that backfiltration may occur.
However, it is possible for the authorized technician to preset the
machine so that when negative TMP alarm limits have been set,
such an attention alarm occurs.
