Air/Oxygen Entrainment Mixer
Figure 3-13. Air/Oxygen Entrainment Mixer
The air/oxygen entrainment mixer (part number MXL70A-XX-XX), which is used to blend atmo-
spheric air with 50 psi medical-grade oxygen, attaches to the fresh gas intake port on the filter
cover (right side of the ventilator). Attach the mixer’s high pressure hose to an active source of
medical-grade, 100% oxygen, before attaching the mixer to the ventilator. The mixer should not
be attached to the ventilator before the circuit check is completed. Make sure that the oxygen
source gas is always on while using the mixer during ventilation.
