Use the mixer’s control knob to adjust oxygen enrichment of the gas delivered to the patient
circuit from 21% to 100%. The mixer does not need readjustment when the PEEP and bias flow
settings or patient’s minute volume change.
Use a calibrated oxygen monitor with alarms (such as the one that is built-in to the ventilator) to
assure that the O
2
that is delivered by the ventilator into the patient circuit matches the pre-
scribed value.
Check the mixer filter (part number FLT3209P) at the time of setup and weekly during use. Replace
when dirty. Reference
Note:
Oxygen source gas must be medical-grade, 100% oxygen.

Low Flow Oxygen Reservoir
Figure 3-14.
Low Flow Oxygen Reservoir
The low flow oxygen reservoir (part number RSV3215A), which is used to blend atmospheric air
with 1–10 L/min of medical-grade oxygen, attaches to the fresh gas intake port on the filter cover
(right side of the ventilator). Attach oxygen supply tubing between the oxygen flow meter and
the small bore connector on the reservoir. Attach the reservoir to the ventilator.
Use the oxygen flow meter to adjust oxygen enrichment of the gas delivered to the patient circuit.
When the low flow reservoir is in use, the percent of oxygen that is delivered from the ventilator
into the breathing circuit will vary, depending on the use of bias flow and PEEP, the delivered
minute volume, and the percent O
2
of the source gas.
