Overview

Connecting the
Pipeline Gas Supply
The Narkomed 2B is a continuous flow anesthesia system with
pneumatic circuitry for mixing and delivering gases and anesthetic agent
vapor. The pneumatic system can deliver up to four gases and one
anesthetic agent simultaneously. Oxygen and nitrous oxide are standard
on all machines; available optional gases include air, carbon dioxide, and
oxygen-helium (heliox). Up to three vaporizers can be mounted on the
machine; available vaporizers are for halothane, enflurane, isoflurane,
sevoflurane, and desflurane.
Gas from the hospital pipelines enters the Narkomed 2B through hoses
connected to indexed inlets located on the side of the flowmeter housing.
Depending on the country's standards and regulations, the available
inlets are Diameter-Indexed Safety System (DISS) inlets (body or nut
fitting), or National Institute for Standards and Technology (NIST)
inlets.
To connect a pipeline supply to the Narkomed 2B:
1. Connect the gas fitting on the supply hose to the corresponding gas
fitting on the side of the flowmeter housing. Use a wrench to tighten
the hex nut.
WARNING: Carefully check hoses each time you connect a machine to
a wall or ceiling outlet to ensure that both ends of the hose
are indexed for the same gas. Pipeline delivery hoses used
between wall outlets and anesthesia machines have caused
accidents when, during assembly, an oxygen fitting was
placed on one end of the hose and a nitrous oxide fitting
on the other end.
2. Connect the other end of the supply hose to the appropriate
functioning hospital pipeline supplies.
3. Check the pipeline pressure gauge on the front of the Narkomed 2B
for sufficient pipeline pressure (50-55 psi).
