Volumetric Accuracy Testing
Description
A predetermined amount of water is delivered into a collection device
such as a burette or graduated cylinder. e amount of water delivered is
compared to the amount that the pump is programmed to deliver.
Nominal system accuracy is given in the technical specications section
for the pump. at is, under the test conditions described below, the ac-
curacy of the pump and Medication Cassette Reservoir will be nominal
with a 90% condence level. e nominal test conditions are as follows:
degassed water at 25 ± 5°C without back pressure.
Equipment needed
50 or 100 ml Medication Cassette Reservoir with attached CADD™
Extension Set with Anti-Siphon Valve OR
50 or 100 ml Medication Cassette Reservoir with ow stop feature
with attached CADD™ Extension Set (catalog numbers start with
21-73xx)
50 or 60 ml syringe
A uid collection device such as a burette or a Class A, 25 ml capac-
ity graduated cylinder
40 ml of room temperature water
Procedure
1. Fill the 50 or 60 ml syringe with 40 ml of water. Transfer the water
into a Medication Cassette Reservoir.
2. Remove any air from the Medication Cassette Reservoir by aspi-
rating the air with the syringe. Attach the CADD™ Extension Set.
Prime the tubing so it is lled with uid to the end of the extension
set Luer.
3. Attach the end of the extension set to the uid collection device.
4. Attach the cassette to the pump. Program the Reservoir Volume to
20 ml. is is the intended delivery volume. Remove all clamps.
