General Description
Fresh Gas
Oxygen Sensor
Adapter
The optional fresh gas adapter allows the Narkomed 2B to monitor the
fresh gas oxygen concentration when using a nonrebreathing circuit
(other than a Bain Circuit). The fresh gas adapter fits securely into the
fresh gas outlet of the anesthesia machine. It incorporates a port for an
oxygen analyzer sensor and a fitting for a non-rebreathing circuit.

WARNING: The fresh gas oxygen sensor adapter measures the fresh
gas oxygen concentration, not the inspiratory oxygen
concentration. Depending on the fresh gas flow and the
respiratory minute volume, the inspiratory oxygen
concentration may be lower than fresh gas oxygen
concentration due to rebreathing of previously exhaled
gases.
