WARNINGS
To be used only by a professional trained in the use of nitrous oxide.
Patient should always be closely monitored during nitrous oxide use. If patient
has an adverse reaction, reduce or stop the flow of nitrous oxide as needed. The
O2 flush button can be used to rapidly purge the lines of N2O. If patient does not
show signs of quick recovery, remove nasal hood and treat with pure oxygen from
either the O2 resuscitator fitting or an auxiliary oxygen tank using a demand valve,
oxygen assisted manual resuscitator, or equivalent. Call for emergency assistance if
rapid response is not achieved.
Do not use this device for the administration of general anesthesia or as part of, or
in conjunction with, a general anesthesia administration system.
For use with 100-240 V AC, 50/60 Hz only.

tags to them.
When one of the in-use tanks is empty, close the tank by turning the valve
clockwise. Leave the empty tank in place.
Move the “in-use” tag to the appropriate reserve tank, which now becomes
the in-use tank. Replace the empty tank with a new tank, which then becomes
the reserve tank.
Open the valve of the new in-use tank by turning counterclockwise.
Note: Do not open the reserve tank until the in-use tank is empty. When
changing gas tanks, make certain both same gas cylinders that are
involved in the exchange are closed. Always remember to switch
the “in- use” tags over to the new tanks.
Contact gas supplier to request new gas cylinders as needed.
Digital Newport: Changing Gas Cylinders
Always use clean, dry medical grade gases. Introduction of moisture or other
contaminants into Accutron Analgesia gas machines may result in defective
operation.
The Digital Newport Flowmeter System is designed to operate with a
50-55 psi line pressure on each gas (O2 and N2O). The line pressure can be
determined by reading the O2 and the N2O line pressure gauges that are located
on the front panel of the Newport.
The Newport has features incorporated to make cylinder change-out easy. To
assure proper operation of the system, 4 cylinders must be properly installed at
all times. Please review the following cylinder replacement procedures before
attempting to change cylinders.
Note: Power Cord must be either unplugged from socket or unwound from
storage cleats when opening Newport.
