Gas Delivery System

Overview

The Narkomed GS 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 and carbon dioxide. As many as two or 
three vaporizers can be mounted on the machine, depending on the model. 
Available vaporizers are for halothane, enflurane, isoflurane, sevoflurane, 
and desflurane.

Connecting the Pipeline Gas Supply

Gas from the hospital pipelines enters the Narkomed GS 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. The 
available gas inlets are shown in Figure 5-1.

To connect a pipeline supply to the Narkomed GS:

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 GS for 

sufficient pipeline pressure (50-55 psi).
