Operation
The unit has been designed to ease the learning transition commonly associated with new
equipment. Turning the POWER switch to "1" starts an internal Self Check and begins
operation with the default settings. The operator has the option of delivering volume targeted or
pressure targeted breaths. An internal blender enables the unit to deliver oxygen concentrations
from 21 to 100% using its internal compressor and/or a standard medical-grade oxygen source.
Additionally, low-pressure oxygen can be entrained through the Fresh Gas/Compressor Intake
using the reservoir accessory except when a chemical/biological filter is connected. When
using the reservoir, the FIO

operator should titrate the flow of oxygen to the reservoir to maintain an adequate SpO

Modes of Operation
The unit offers a range of modes using both pressure and volume targeting that can be selected
to optimally manage the patient.
Assist/Control (AC) -- The patient receives either controlled or assisted breaths. When the
patient triggers an assisted breath, they receive a breath based on either the volume or pressure
target.
Synchronized Intermittent Mandatory Ventilation (SIMV) -- The patient receives
controlled breaths based on the set breathing rate. Spontaneous breaths can be either
unsupported demand flow or supported using Pressure Support. (This mode is not available in
the AEV
Continuous Positive Airway Pressure (CPAP) -- The patient receives constant positive
airway pressure while breathing spontaneously. Spontaneous breaths can be either demand flow
or supported using Pressure Support.

and without Pressure Support. The operator has the option of adding leak compensation
