NOTICE
READ MANUAL COMPLETELY
BEFORE OPERATING THIS DEVICE
The Quality System for Porter Instrument is Certified to ISO 13485. The scope of our registration is:
“The design, manufacture, distribution and servicing of Dental Flowmeters, Gas Scavenging Systems,
Gas Distribution Systems and Office Communication Systems for use in the Dental Profession.”
User Instructions
The Porter System is designed to solve the
problem of exposure to Nitrous Oxide.
Comfortable and quiet, the unique design of the
mask minimizes any “competition” between the
vacuum source and the patient. It allows the
patient to receive the proper amount of Oxygen
and Nitrous Oxide with normal respiratory
effort. The silicon tubing and mask have
increased durability and are steam and
chemical vapor autoclavable.
Porter
features
a
mask-within-a-mask
scavenging system. Metal and plastic parts
have been eliminated from the mask so that xrays can be taken during a procedure without
removing the mask. The mask includes easyto-remove inner liners that simplify cleaning
and sterilization. The soft inner mask provides
an excellent seal around the nose and a
comfortable fit for the patient. Also available,
are single-use personal mask liners for the
Porter Scavenging System.
A Non-Rebreathing Valve (NRV) and
Emergency Air Intake (EAI) located on the bag
tee provide safety features and make the
“breathing bag” the visual barometer for
monitoring the patient’s respiration rate. (See
NRV and EAI tests below.)
Porter Retrofit Kits
Porter Scavenger Retrofit Kits are available for
most brands of flowmeters. You can update
your present nitrous oxide system for improved
safety, durability, and comfort. These kits
provide the standard features of NonRebreathing Valves (NRV) and Emergency Air
Intakes (EAI) - important safeguards your
present system may not have. You can easily
check your current system for these safeguards
using the following tests:
Non-Rebreathing Valve (NRV) Test
Disassemble the fresh gas tubing from the
mask and “Y” connector, and breathe back into
the fresh gas corrugated tubing (Figure 1, Item
9) connected to the flowmeter. You should not
be able to fill the reservoir bag with exhaled
gas. If the bag fills, this breathing circuit has no
NRV and would allow for carbon dioxide (CO2)
buildup in the breathing bag.
Emergency Air Intake (EAI) Test
With the flowmeter turned off and the breathing
bag empty, inhale through the mask. A check
valve assembly should open allowing “room air”
into the breathing circuit. If no room air enters
the breathing circuit, this circuit has no EAI - an
essential component for the safe and effective
administration of Nitrous Oxide and Oxygen.
If your system fails either of these tests, your
system should be updated with a Porter
Scavenger Retrofit Kit.
IMPORTANT: It is not recommended to
retrofit Porter Scavenger Rubber Goods to
A-dec or Veriflo Flowmeters. It is only
recommended to retrofit an AVS to the Porter
Scavenger Systems and Porter Flowmeters,
with the exception of the Porter Oral Surgeon
unit (Model 3000-OS).

5. The bag should stay inflated. If so, the
test has been successful and there are no
excessive leaks.
6. If the bag does not stay inflated, the 3-liter
bag or rubber goods have an excessive
that leak. Replace any parts that leak and
retest until results are successful.
7. Disconnect one of the duplex hoses from
the plastic connector and re-install the
nosepiece. Figure B
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 B.
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 overinflate or “balloon”, then turn the meter off
at the ON / OFF switch.
4. Observe the 3 liter bag for five minutes.

4.3. 100% Oxygen only should be
administered while the mask is being
placed. Flowing Nitrous Oxide while
fitting the mask will significantly
increase N2O ppm (parts per million)
exposures.
CAUTION
The vacuum system should be equipped with a
back flow shutoff device to prevent carryover of
fluids into equipment attached to the piping
systems. It is recommended that a separate
vacuum trap be used between the piping system
and the vacuum station inlet or any equipment
that is attached to the system.
4.4. All Porter masks are sealed (no hole in
the front of the mask). An open air
valve or air dilution technique is not
recommended.
4.5. Flow only the volume of gas required
by the patient. An over-full reservoir
bag indicates excessive gas flow,
which could increase N2O ppm
exposures.
CAUTION
DO NOT PROCESS ANY LIQUIDS OR DEBRIS
THROUGH THE AVS. This contamination can
cause damage and affect the function of the unit.
The AVS is designed to regulate the vacuum
flow level for scavenging of Nitrous Oxide /
Oxygen gas only.
4.6. 100% Oxygen only should be
administered for several minutes at the
end of the procedure. This will flush
the Nitrous Oxide from the patient.
Failure to follow this procedure will
result in higher N2O ppm exposure in
the operatory.
Basic Operation:
For the AVS or Vacuum Control Block (Note:
Use either an AVS or a Vacuum Control
Block, not both):
1. AVS will automatically open upon the
delivery of 1.5 to 3.5 L/min of gas flow. The
Vacuum Control Block is manually operated
and must be opened by pushing “on/off”
toggle to “on” position.
2.
Field Performance Check of Adjustment of
Vacuum Flow Using the AVS:
1.
Set a high flow: After assembly of AVS and
Scavenging System to the Flowmeter, set
flowmeter to flow 8 L/min of 100% Oxygen
to fully open AVS vacuum interlock.
2.
Set vacuum level (green bar or higher):
Turn vacuum control knob to set vacuum
flow, as indicated by the vacuum indicator,
in the desired area *.
Adjust vacuum flow by using vacuum control
knob and acrylic sight glass on side of AVS
or Vacuum Control block. Vacuum flow with
ball float within the green bar area is
effective; ball above green bar is for highest
vacuum flows.
3.
Monitor the vacuum conditions during the
procedure by observing the sight glass;
adjust vacuum flow at any time as
necessary.
4.
Follow
good
work
recommended by NIOSH.
*Porter
recommends
that
effective
scavenging can be achieved with the ball
float in the green bar area of the acrylic sight
glass,
however
NIOSH
publications
conclude that higher vacuum flows of up to
45 L/min are most effective. To meet the
NIOSH recommendation of 45 L/min, adjust
the ball above the green bar area.
as
3.
4.1. Caution the patient not to talk
unnecessarily or breathe through the
mouth.
Close the flowmeter flow to zero. The ball
float will drop to the bottom of the sight
glass.
4.
Check at low flow: Open the flowmeter,
again with 100% Oxygen, slowly to 3.5
L/min. Observe that the AVS vacuum flow
indicator reaches the same level as in the
setting of Step 2.
practices
4.2. The mask must be fitted properly to
avoid leaks. (Pedo mask for children.)

2. Inspect and maintain the analgesia delivery
system to prevent N2O leaks in all hoses,
connections, and fittings. Repair all leaks
immediately.
3. Use scavenging. Exhaust ventilation of N2O
from the patient’s mask should be
maintained at an appropriate air flow rate as
indicated by the calibrated flowmeter sight
glass, and vented outdoors – not into the
room ventilation system.
4. Supply and exhaust vents should be well
separated to allow good mixing and prevent
“short-circuiting.”
5. Fit mask to patient so inner mask is secure to
the face. Outer mask should not be
against face. Vacuum needs to be drawn
into outer mask during inhalation.
6. Use minimum N2O levels to achieve desired
analgesia effects.
7. Monitor work area for N2O to insure controls
are effective in achieving low levels of PPM
exposure. Contact your Porter dealer for
details on monitors and testing.
NOTE: If low flow check does not show high
enough vacuum flow, repeat Steps 1 - 4, and
adjust vacuum control knob to a higher vacuum
flow setting. Effective scavenging is achieved if
vacuum flow can be verified to be within the
green bar area of the acrylic sight glass.
However, if the check of Step 4 fails, it may be
an indication that the AVS requires
maintenance. Contact your Porter dealer.
Cleaning Methods:
For cleaning the AVS and accessories, we
recommend the use of an approved disinfectant
for the dental environment. Follow the
disinfectant manufacturer’s directions for use and
their cautions. Recommended methods for
cleaning and sterilizing rubber goods are listed in
the chart.
System Maintenance, Ventilation and Work
Practices:
1.
It is advisable, on a two (2) year cycle, to
have the AVS and flowmeter factory
checked and serviced.
Recommended Methods for Cleaning and Sterilizing Porter Nasal Assembly
NOTE: The following items are not autoclaveable:
Fresh Gas Tubing, 3L Latex Bags and Vacuum Control Valves.
Nasal Hood and Liners
Before cleaning, remove inner mask from hood. Pinch top and bottom of inner
mask with thumb and forefinger then pull toward center. Follow recommended
cleaning and sterilization as detailed in chart with hood and liner still
separated. Then, replace inner mask into hood by pushing the tube
connectors into large holes with thumb or forefinger.
W A R N I N G : Chemical Disinfectants should not be used!
Disinfectants do not provide the same reduction in microbial contamination levels
as sterilization. These techniques can leave a residue on the mask and liner that
can irritate or even chemically burn the patient’s skin or mucous membranes if the
mask / liner is not rinsed thoroughly with clean water.

Chemical Vapor Sterilizer: Let cleaned items dry completely then sterilize on any cycle
recommended by the sterilizer manufacturer.
Dry Heat Sterilization and Chemical Disinfectants should not be used!
WARNING:
Dental workers are exposed to Nitrous Oxide (N2O) during administration of N2O/ O2 conscious
sedation analgesia. NIOSH has recommended that exposures should be minimized. Contact NIOSH
(1-800-35-NIOSH) to receive NIOSH Publications on Control of Nitrous Oxide in Dental Operatories.
Exposure can be minimized by effective controls. National Institute for Occupational Safety and Health
(NIOSH) publications state that controls, including System Maintenance, Ventilation and Work
Practices can effectively reduce N2O concentrations in dental operations. Your Porter Scavenger
System is an important part of the system of controls.
