8. Select Operating Mode (Optional)

The ventilator offers four operating modes that you can select to optimally manage the patient
(each mode can use either pressure or volume targeting):
1. AC (Assist/Control) -- 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.
SIMV (Synchronized Intermittent Mandatory Ventilation)-- The patient receives controlled
2.
breaths based on the set breathing rate. Spontaneous breaths are either unsupported demand
flow or supported using Pressure Support. (This mode is not available in the AEV
CPAP (Continuous Positive Airway Pressure) -- The patient receives constant positive
3.
airway pressure while breathing spontaneously. Spontaneous breaths are either demand flow
or supported using Pressure Support.
BL (bilevel) -- the ventilator provides two pressure settings to assist patients breathing
4.
spontaneously: a higher inhalation pressure (IPAP) and a lower exhalation pressure (EPAP).
To select the operating mode, press the Mode parameter button, turn the selection dial to
highlight the mode you want to use, and press the Accept/Select button.
When transitioning from active ventilation to NPPV modes, or from NPPV Modes to active
ventilation modes, the following parameter/alarm limit may be adjusted:
Alarm/Parameter
Low BPM Alarm
High BPM Alarm
Low Airway Pressure Alarm
PEEP
V High Limit
T
V Low Limit
T
Rise Time
Pressure Support
Warning! The transition into NPPV automatically sets the rise time to 3, which may be too fast for
infants and small children. Before using the ventilator with an infant or small child, you
should always configure the ventilator appropriately before attaching the patient.

An alarm triggers when you connect the patient to the ventilator while the Start Menu
is still active. To resolve the alarm, you must select a mode of ventilation and configure
the device appropriately for the patient. In addition, you should perform the
Operational Test procedure before reconnecting the patient to the device.
