Annual Inspection and Testing
14. Remove the CADD
™
medication cassette reservoir from the pump and weigh the entire
CADD
™
medication cassette reservoir/CADD
®
extension set assembly. This is the
postdelivery weight.
15. Calculate the difference in weight between the predelivery weight and the postdelivery weight.
This is the weight of the amount delivered.
16. Find the difference between the actual delivery volume and the intended delivery volume. This
is the inaccuracy volume.
17. Divide the inaccuracy volume by the intended delivery volume and multiply by 100. This is the
accuracy error percentage.
18. 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.
Example:
Pre-delivery Weight
61.1 g
Post-delivery Weight
– 41.6 g
Weight of Amount Delivered
= 19.5 g
Actual Delivery Volume
19.5 mL
Intended Delivery Volume
– 20.0 mL
Inaccuracy Volume
= - 0.5 mL
Inaccuracy Volume
– 0.5 mL
Intended Delivery Volume
÷ 20.0 mL
Accuracy Error
= - 0.025
Accuracy Error
– 0.025
× 100.00
Accuracy Error Percentage
= - 2.5%
