5. If desired, adjust the automatically set venous pressure alarm
limits as necessary using the Keypad . Start by adjusting the
high alarm limit. Then, during the arterial phase, gradually
adjust the low venous pressure alarm limit as well. Make
sure that the venous pressure alarm limits remain within
the limits recommended by the clinic for that particular
patient's blood access. See the next following Note for
further information about this setting.
6. If necessary, adjust the level in the venous expansion
chamber. The level should be as low as possible (i.e. without
air passing into the blood lines at the end of the venous
phase), in order to best achieve a proper stroke volume
(
STROKE
).
7. Check that the current stroke volume (
STROKE
) shows a
proper value. See "Glossary of single needle parameters and
key terms" on page 5:2 in part 1 for further information.
8. Press the fl ashing UF Start/Stop button (lights up) to start
ultra fi ltration. Note especially that at all times whenever
necessary during treatment, the UF Start/Stop button can
be pressed ( fl ashing) in order to decrease the UF rate to
minimum UF rate.
Check that the minimum UF rate is set to the correct value.
Press the Fluid Path button , select
UF
and check the value in
SET MIN UFR
. Adjust if necessary.
Note
•
The achieved stroke volume is determined by the size and
position of the venous pressure alarm window. The wider the
window, the greater the stroke volume. The higher the position
of the window, the higher the venous fl ow. Set the venous
pressure alarm limits in such a way that a proper stroke volume
is being achieved. Bear in mind that as the venous pressure
alarm limits are used to control the arterial and venous phases
the extracorporeal circuit must continuously be monitored
by visual inspection. A decreasing stroke volume and/or a
decreasing mean blood fl ow rate may indicate clotting or a
kinked venous blood line.
