An oxygen source can be supplied from an in-house line, tank, or an Oxygen Concentrator.

Oxygen Regulation – The oxygen functions as a carrier for the anesthetic gas and serves as a blending agent to control the concentration of anesthetic. The oxygen regulator controls the pressure of oxygen from the tank into the anesthesia machine. The O2-20 and O2-12 Oxygen Concentrators eliminate the need for oxygen tanks or an in-house oxygen source.
