NOTE:
The pressure from the source must be zero
when the cassette is attached.
3. Assemble the apparatus as shown in Figure 9.
4. Connect the Medication Cassette™ reser-
voir outlet tube to the metered pressure
source.
NOTE:
Do not use a CADD
®
extension set with
anti-siphon valve.
5. Start the pump and run at 30 ml/hr.
6. Slowly increase the back pressure, noting
when the high pressure alarm is activated.
NOTE: The pressure may be increased
rapidly to 8 psi, after which the pressure
should be increased at 3 psi/min or less until
the alarm sounds.
7. The high pressure alarm should sound
between 9 and 27 psi (18±9 psi).
Upstream Occlusion Sensor Test (Model
6101 pumps only)
Description
The tubing between the fluid reservoir and the
pump is occluded while the pump is running
until the occlusion alarm sounds.
Equipment needed
• CADD
®
administration set with anti-siphon
valve.
• Tubing clamp (slide clamp or hemostat)
5. Program the pump to the following param-
eters:
Reservoir Volume: 10.0 ml
Units: Milligrams
Concentration: 1.0 mg/ml
Continuous Rate: 0.0 mg/hr
Demand Dose: 1.0 mg
Demand Dose Lockout: 0 hrs 5 min
Max Doses Per Hour: 12
Dose Counters: 0/0 (Press the ENTER
key to clear)
Milligrams Given: 0.0 mg (Press the
ENTER key to clear)
6. Start the pump. When the pump is running,
activate a Demand Dose, noting when the
high pressure alarm is activated.
7. The pump should alarm when the pump
delivers between 1 and 2 activations.
CAUTION:
At the completion of the test, the pressure
must be reduced to zero before detaching the
cassette from the pump; otherwise, the
cassette may rupture. Safety glasses should be
worn while conducting or observing this test.
Downstream Occlusion Pressure Range
Test (Option 2)
Description
An adjustable metered pressure source is
connected to the Medication Cassette reservoir
tubing. The pressure is slowly increased until
the high pressure alarm sounds.
Equipment needed
• Pressure gauge, 30 psi ± 1 psi.
• Pressure vessel, partially filled with water.
• Pressure regulator, 30 psi.
• 50 or 100 ml Medication Cassette reservoir
containing water.
Procedure
1. Insert a battery and wait for the pump to
power up.
2. Attach a Medication Cassette reservoir to the
pump. Latch and lock the cassette.
