6/5/96 D. Zurn, Occlusion Set-up Prizm 6/96

Downstream Occlusion Pressure Range

Test (Option 1)

Description

Pressure is generated by activating the

pumping mechanism with an attached filled,

clamped CADD

™

medication cassette reservoir.

The pump is started and a Demand Dose is

given until the high pressure alarm sounds.

Equipment needed

50‑ or 100‑ml CADD

™

medication cassette

reservoir containing water

Procedure

1. Insert a battery and wait for the pump to

power up.

2. Attach a CADD

™

medication cassette

reservoir containing water to the pump.

Latch and lock the cassette.

3. Prime the CADD

™

medication cassette

reservoir tubing. The tubing should be

filled with fluid to the end of the luer lock

connector. The system

must

be free from

air bubbles for this test.

4. Close the slide clamp on the distal end

of the tubing near the female luer of the

CADD

™

medication cassette reservoir.

5. Program the pump to the following

parameters:

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

Delivery Limit

No Limit

Reservoir Volume

10.0 ml

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.

Downstream Occlusion Pressure Range

Test (Option 2)

Description

An adjustable metered pressure source is

connected to the CADD

™

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 CADD

™

medication cassette

reservoir containing water

Procedure

1. Insert a battery and wait for the pump to

power up.

2. Attach a CADD

™

medication cassette

reservoir to the pump. Latch and lock

the cassette.

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 CADD

™

medication cassette

reservoir 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

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)

Procedure

1. Spike an appropriate standard I.V. bag
2. Prime the entire fluid path
