Appendix A

Optional Manometer Testing

Although Codman does not recommend functional
testing, some surgeons might choose to do so. Before
testing, it is extremely important that a CODMAN CERTAS
Programmable Valve with or without SIPHONGUARD
Device be flushed of all air bubbles. Air bubbles within the
valve or SIPHONGUARD Device will produce inaccurate
manometer test results. The presence of air bubbles can
reduce the cross-sectional area of the flow path, increase
system resistance, and impede the flow of fluid through
the system during testing.

SIPHONGUARD Device Functional Testing

Equipment Required (use all sterile equipment, perform
testing under sterile conditions)
One sterile manometer, wide-bore (e.g. 3.5 mm),
graduated in mm (available in lengths from 38 to 60 cm)
One sterile 4-way stopcock
One sterile syringe, 10mL minimum is recommended
One sterile syringe filter, 5 µm
Sterile tubing adapters
Sterile silicone tubing
One sterile male luer connector with 1/16 in. (1.6 mm) barb
Sterile saline solution
Flushing Procedure
Note: At a rate of 0.5 mL/minute, unitized versions
require 2–3 minutes to complete flushing. This is the
time required for fluid to fill the valve and exit the distal
catheter. Allot additional time to ensure the system is
free of air bubbles.
1. Fill syringe with sterile saline using the 5 µm syringe
filter. The syringe filter should not be reused in any
subsequent refilling of the syringe. Once the syringe
has been filled, remove the filter from the syringe.
2. Assemble manometer, stopcock, syringe, and tubing
(Figure A-1).
3. Adjust the valve setting to 1 while the valve remains in
its sterile package.
4. Remove valve from the sterile package, and connect
the valve to the manometer/syringe assembly.
5. Adjust the stopcock to connect the syringe to the
valve assembly (Figure A-2).
6. Position the valve vertically with the outlet
pointed downward.
7. Using the syringe, gently flush saline through the
system while gently pressing the reservoir to purge air
bubbles from the valve assembly. Once fluid begins
flowing through the valve mechanism, the outlet of
the valve can be pointed upward to further assist in
evacuating air from the system.
