Manometer Testing; Equipment Setup - Integra Codman CERTAS Plus Manual Del Usario

7 . Repeat Steps 3 through 6 as necessary to reconfirm
SIPHONGUARD function.

Manometer Testing

Note: Performing a manometer test is not recommended as this
test is susceptible to environmental factors and yields a result
that is not physiologic in nature and for which manufacturers do
not specify performance ranges.
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
Sterile fluid reservoir or water bath

Equipment Setup

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 . Place the end of the tubing leading from the stopcock into
the water bath. Position the tubing so that the end does not
come into contact with the sides of the bath.
4 . Adjust the manometer height so that the zero level of the
manometer and the fluid level in the water bath are at the
same level (Figure A-5).
5 . Adjust the stopcock to connect the syringe to the tubing in
the water bath (Figure A-2).
6 . Using the syringe, flush the stopcock and tubing with sterile
fluid to purge the system of air.
7 . Turn the stopcock to connect the fluid pathway from the
syringe to the manometer (Figure A-6).
8 . Using the syringe, fill the manometer to a minimum of 10 cmH
Zeroing the Manometer
1 . After filling the manometer, turn the stopcock to connect the
manometer with the bath (Figure A-7).
2 . Allow the water column in the manometer to fall. The water
column should stop at the zero level of the manometer
(Figure A-8).
3 . If necessary, adjust the height of the manometer to bring the
water level in the manometer to the same level as the fluid in
the water bath.
Test Procedure
1 . Adjust the valve to desired setting while the valve remains in
its sterile package.
2 . Remove valve from the sterile package, and connect the valve
to the manometer/syringe assembly using the tubing placed
in the water bath.
3 . Adjust the stopcock to connect the syringe to the valve
assembly (see Figure A-2).
