Installation
Front and Back of the VentElite
Initial Setup
1. Remove unit from the box
2. Remove foam-packing inserts from both ends of the ventilator
3. Locate and carefully remove the power supply and line cord from the
shipping material
4. Visually inspect the ventilator for any damage that might have occurred in the
shipping process
5. The VentElite is shipped from the factory with a North American line cord with a US
three wire molded power plug on one end and an IEC320/C13 connector on the
other end. Use only an approved AC line cord with a molded IEC320/C13 connector
certified for country of use. Only connect to grounded power receptacles to help
ensure proper grounding; do not use adapter plugs.
6. Read the manual to become familiar with all features and functions of the VentElite
Location Requirements
• A sturdy, level, clean, nonflammable and dry surface
• Minimum of 2.5 cm (1 in) clearance around the ventilator
• Adequate power supply
• Room temperature 4° to 40°C (40° to 104°F)
• Relative humidity of 20 to 80% (see chart in Technical Specifications section)
• A well ventilated room
WARNING
Do not use in the presence of explosive gases
or in a high concentration oxygen environment
Volume Control Mode The VentElite delivers a known volume of gas to the subject
on each inspiration stroke. Respiration frequency and I:E
ratio determine the amount of time for inspiration and
expiration phases.
Pressure Control
Mode
The ventilator delivers gas to the subject until the user-
defined pressure limit is reached. Stroke volume is
automatically adjusted by the unit so that the pressure limit
is reached near the end of the stroke. Respiration frequency
and I:E Ratio determine the amount of time for inspiration
and expiration phases
Tidal Volume (Vt)
Adjustable from 50 µl to 5 ml with user selectable units
Respiratory Rate (BPM) Adjustable from 10 to 300 BPM
Adjustable I:E Ratio
This option allows the user to select the ratio of inhalation
to exhalation times when advanced respiratory control is
needed. This feature is intended to allow greater respiratory
control for research applications. The default I:E ratio is
50% and is user selectable from 20 to 80%, depending on
respiration rate.
Sigh Breath
Continuous, long-term ventilation combined with the
force of gravity will cause the animal’s lungs to collapse.
Introducing a larger than normal tidal volume over-inflates
the animal’s lungs, replicating a natural sigh. This allows the
lungs to expand and open the collapsed alveoli. Sigh breaths
are supported in both Volume Control and Pressure Control
modes. In the Volume Control mode, a sigh tidal volume is
used. In the Pressure Control mode, a sigh pressure limit
is used. The frequency and volume of the sigh breath are
user selectable via the Sigh button on the user interface.
Sigh frequency can be programmed automatically or can be
controlled manually by pressing the Sigh button on the user
interface.
Positive End
Expiratory Pressure
(PEEP)
Positive End Expiratory Pressure (PEEP) is user selectable, up
to 10 cmH
2
O, depending on peak inspiratory pressure (PIP).
Inspiratory/Expiratory
Hold
User selectable option for toggling between inspiratory
or expiratory hold, for user defined time to maintain peak
(inspiratory) or minimal (expiratory) tidal volume/pressure in
the subject’s lungs
Safety Alarms
Visual and audible alarms for over pressure, under pressure,
occlusion, and high PEEP – as well as option to Mute All
alarms
