4.3 Occlusion Pressure/
Bolus Volume Testing
To protect the patient, an infusion device should include an occlu-
sion pressure alarm. This alarm should activate if the pressure inside
the administration set exceeds preset levels. Since an occlusion with
built up pressure also distends the administration line, an excess vol-
ume of liquid is stored in the line. This is the
Bolus volume , which is
a discrete quantity of liquid delivered in a short time, and is not in-
tended to form a part of the continuous flow output. Such uncon-
trolled volume may also be a risk to the patient, and must be mea-
sured for the infusion pump.
1. Prime the QA-IDS as per paragraph 4.2.2 above.
2. Press Occlusion Test (F5) in the Main Menu and the fol-
lowing display will appear:
3. Press Flow Set (F7) to select an intermediate flow rate on
the infusion device.
4. Press Alarm Prsr (F6) to enter a preset pump value on
pumps having programmable occlusion alarm settings.
5. Press Pump Type (F5) and select between the two options:
Standard or Reversing .
6. Start the infusion, and simultaneously press START (F2) to
start the Occlusion Test, and the following display will ap-
pear.
During the test, the pressure ( Prsr ) in the administration set and
elapsed time will be displayed. When the Occlusion Alarm on
the infusion pump is activated, press
STOP (F2) to stop the
test, and the following display will appear.
