3. UI Arm
The UI Arm provides support for the user interface assembly. It can easily rotate for more
convenient viewing.
4. Oxygen Sensor
The Oxygen Sensor monitors the oxygen concentration of the inspired gas of the Breathing
System.
5. Breathing System
The Breathing System’s main function is to store anesthetic gas, oxygen, and air; vent exhaust
gas; and absorb carbon dioxide. It connects directly to the respiratory passage to help
complete the breathing process.
6. CGO (Common Gas Outlet) Subassembly
Mixed gas composed of O
2
, AIR, N
2
O, and anesthetic agent connects to the patient's
Breathing System via a flexible tube from the CGO Subassembly.
7. O

Flush Valve
The O
2
Flush Valve is located on the front of the AS3000 . The supplied gas does not pass
the flowmeter and vaporizer. It is directly sent to the fresh gas outlet. Press this button to
supply gas (35 - 50 L/min). Release this switch to automatically close the gas supply.

, and Auxiliary AIR.
It consists of coarse and fine flow tubes used to accurately measure gas flow with additional
flow tubes to measure auxiliary O
2
and AIR gas flow.
