Oxygen tank regulator with a delivery rate
preset at 50 psi. Outlet is a DISS male connection.

"Carrier gas," usually oxygen, is supplied from a cylinder, large or small, in the procedure room, on the anesthesia cart, or piped through the walls.

If you facility has "piped in" oxygen, you will see either wall plate outlets, gas faucets or drop lines in your procedure area.

If you do not have piped in oxygen, you will need to have a cylinder in your procedure area. Standard sizes are "E" and "H" Most facilities do not own the cylinders, they rent them from a gas supplier. The supplier will rent the cylinders but not the regulators that are required to lower the cylinder pressures to 50 psi. Anesthesia machines need non-adjustable regulators that are preset to 50 psi.
