POWER OXYGEN FLUSH
CHECK MONTHLY
(O
2
SUPPLY PRESSURE AT 50 PSIG)
Disconnect the corrugated rubber tubing from
the bag tee outlet (Figure 1, Item 11). With
both control knob valves OFF, depress the
power (O
2
) flush button while blocking the
flow from the front of the bag tee. For proper
operation, the gas reservoir bag should fill
within about 5 seconds. Also test for bag /
rubber goods leak following steps 1 through
6.
Quick Test to Check 3 Liter Bag / Rubber
Goods for Leaks
1. With the flowmeter, bag tee and Porter
rubber goods in place, remove the
nosepiece and one of the two plastic
connectors from the Porter rubber goods.
Refer to Figure 2.
2. With the other plastic connector, join the
two duplex hoses together making a
closed system.
3. Taking care not to fill the bag too much
(bag could burst), open the oxygen control
valve until the 3 liter bag starts to over-
inflate or “balloon”, then close the valve.
4. Observe the 3 liter bag for five minutes.
5. The bag should stay inflated. If so, the
test has been successful and there are no
excessive leaks. If the bag does not stay
inflated, the 3-liter bag or rubber goods
have an excessive leak. Replace any
parts that leak and retest until results are
successful.
6. Disconnect one of the duplex hoses from
the plastic connector and re-install the
nosepiece.

BAG TEE
The Bag Tee assembly features a Non-
rebreathing Valve and an Emergency Air
Intake located on the Bag Tee, which comply
with American Dental Association guidelines.
The non-rebreathing valve has a back flow
check valve, which prevents exhaled gases
from entering the breathing bag (no carbon
dioxide buildup). The emergency air intake
has a valve that allows room air to be inhaled
into the breathing circuit by the patient. A
breathing bag is attached to the metal portion
of the Bag Tee and is a reservoir bag for the
delivered analgesia gases, which when taken
together with the two valves above, becomes
the visual barometer for monitoring the
patient’s respiration rate. The bag moves in
and out with each inhalation and exhalation.
