GAS DELIVERY SYSTEM
Standard Gases
The NARKOMED 3 is equipped with
pneumatic circuitry for the delivery of
oxygen (O
) and nitrous oxide (N
2
has at least one oxygen and one nitrous
oxide yoke for attachment of gas cylinders.
Optional Gases
In addition to oxygen and nitrous oxide,
the NARKOMED 3 may be equipped with
up to two additional gases. The additional
gases may be air, oxygen-helium (O
mixture (25% O
, 75% He) or carbon
2
dioxide (CO
). The additional gas is
2
supplied to the anesthesia system by
means of pin-indexed cylinders and yokes,
diameter-indexed safety system (DISS)
pipeline
connections,
selected).

Pipeline Connections
The DISS gas fittings for oxygen, nitrous
oxide, and an optional third gas are located
on the right side of the flowmeter housing.
The
DISS
fittings
connection of supply hoses. The inlets
include check valves to prevent back flow
leakage into the atmosphere when supply
hoses are not connected, or into the
attached supply hoses when reserve
cylinders are in use.
Each pipeline connection is equipped with
a filter to prevent foreign material from
entering the internal gas piping of the
NARKOMED 3. Pipeline gases should be
supplied at 50-55 psi.
