Volumetric Accuracy Testing
Description:
A predetermined amount of water is delivered into a collection device such as a burette or graduated
cylinder. The amount of water delivered is compared to the amount that the pump should have
delivered.
Nominal system accuracy is given in the technical specifications section for the pump. The nominal
test conditions are: degassed water at 25 ± 5°C without back pressure.
Equipment needed:
•
CADD
™
medication cassette reservoir with attached CADD
®
extension set or
CADD
™
medication cassette reservoir with flow stop feature with attached CADD
®
extension set
•
50 mL or 60 mL syringe
•
A fluid collection device such as a burette or a Class A, 25 mL graduated cylinder
•
40 mL room temperature water
Procedure:
1. Fill the syringe with 40 mL water.
2. Transfer the water into a CADD
™
medication cassette reservoir. Remove any air from the
CADD
™
medication cassette reservoir by aspirating the air with the syringe.
3. Fill the syringe with 3–5 mL water.
4. Attach the syringe to the end of the CADD
®
extension set that does not contain the anti-siphon
valve. Prime the tubing so it is filled with fluid to the end of the CADD
®
extension set.
5. Secure the clamp on the CADD
®
extension set.
6. Remove the CADD
®
extension set from the syringe and attach it to the CADD
™
medication
cassette reservoir.
7. Attach the end of the CADD® extension set to the fluid collection device.
8. Attach the CADD
™
medication cassette reservoir to the pump.
9. Program the reservoir volume to 20 mL. This is the intended delivery volume. Open all clamps.
10. Program a continuous rate of 0.0 mL/hr and a PCA dose of 20.0 mL.
11. Start the pump and deliver a PCA dose of 20 mL.
12. When delivery is complete, record the volume of fluid delivered. This is the actual delivery.
13. Find the difference between the actual delivery volume and the intended delivery volume.
This is the inaccuracy volume.
14. Divide the inaccuracy volume by the intended delivery volume and multiply by 100. This is the
accuracy error percentage.
15. If the accuracy error percentage is greater than ± 6%, repeat the test with a new CADD
™
medication cassette reservoir. If the pump fails a second time, call Smiths Medical.
