Adding Supplemental Oxygen to the Device

The delivered oxygen concentration varies with changes in ow
in the circuit. The following may have an impact on oxygen
concentration:
•Pressure settings
•Patient Tidal Volume

•Respiratory rate
•Circuit leak rate
•Oxygen ow rate
To add oxygen to the circuit, the oxygen supply must comply with the
local regulations for medical oxygen. The oxygen ow into the oxygen
valve cannot exceed 15 l/min and the pressure cannot exceed 50 psi.
