Medfusion® Model 3500 pump V6 Operator’s Manual
Note: FlowSentry
™
pressure monitoring is disabled
at rates greater than roughly ⅓ of the syringe size per
hour. See the table at right for more information.

In this way it can easily be seen that a) FlowSentry
™
pressure monitoring is activated, and b) whether
the delivery pressure is stabilizing, steady, or
increasing. In the event that the FlowSentry
™
pressure
monitoring has not been activated there will be no #
or arrow signs to the left of the pressure trend graph.
FlowSentry
™
pressure monitoring is automatically
disabled when the delivery rate for a syringe size is
exceeded as indicated in the following table:
Syringe Size
FlowSentry
™
maximum
infusion rate
60 mL 20 mL/hr
50 mL 20 mL/hr
35 mL 12 mL/hr
30 mL 10 mL/hr
20 mL 6.6 mL/hr
12 mL 3.3 mL/hr
10 mL 3.3 mL/hr
6 mL 1.65 mL/hr
5 mL 1.65 mL/hr
3 mL 1 mL/hr
If FlowSentry
™
pressure monitoring is disabled, the
bar graph is still shown, however none of the icons (#,
≥
or
¤
) will appear on screen.
Post occlusion bolus reduction
With large syringes, fluid can accumulate or be
“stored” in the line when an occlusion happens,
which is then delivered as a bolus when the occlusion
is released. This stored volume is the result of the
volume of the syringe and infusion set increasing
under pressure. The pump contains a feature for
reducing this bolus upon occlusion release (or
occlusion bolus).
Using post occlusion bolus reduction, the pump
withdraws the plunger a predetermined amount to
reduce “stored” bolus in the syringe. However, this
feature does not totally eliminate the occlusion bolus.
Occlusion bolus will vary greatly with occlusion limit
setting, syringe size, and the fluid infused. The post-
occlusion bolus reduction feature decreases bolus on
occlusion release to less than 0.3 mL.
WARNING:
Larger size syringes at occlusion setting
HIGH may produce a post occlusion bolus larger
than 0.3 mL due to excessive syringe plunger tip
compliance.
