Pressure Alarm Limits Setting
Alarm Limit Centralizing Function
The machine is equipped with a centralizing function to simplify the
correct setting of the alarm limits for arterial pressure and for TMP.
The centralizing function means that when the Arterial button is
fl ashing, the button is to be pressed. When pressed, the alarm window
will automatically be set around the current value. For TMP, the
TRANSMEMBRANE PRESSURE CONFIRM MENU
appears, where
the operator con fi rms the automatically set TMP alarm limits.
The size of the alarm limit windows, and where on the pressure scale
they are placed, vary for the two parameters and can be preset by an
authorized technician. The default values which the machine is preset
with upon delivery, can be read in chapter 9, "Technical Data and
Speci fi cations" in part 1. If the centralizing function is removed, or if
wide alarm limits range are preset, it is the operator's responsibility the
make sure that the alarm limits are properly set around the current
values during treatment.
Arterial Pressure
Press the Arterial Pressure button (when fl ashing) to centralize the
alarm limits around the current value.
If necessary the alarm limits can be manually set/adjusted within
the preset alarm window. Press the Arterial Pressure button and the
pressure menu will be shown on the Information Display. Manually
adjust the alarm limits using the Keypad , see "Arterial Pressure button"
in chapter 3 for instructions manual setting of the alarm limits.
The alarm window will automatically be widened and the button
starts 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
Venous Pressure
The alarm limits are to be manually adjusted. See in previous
instructions, "Start the Treatment". point 5.
