Introduction
1 Introduction
Please read this manual carefully before using the device.
This manual is provided with the VS III™ device you have received. It
does not in any way replace the clinical manual supplied to your
physician or HME provider.
The VS III is designed to provide ventilation to all patients, whether or not
they are ventilator-dependent. It can deliver invasive ventilation (via a
tracheostomy tube, for example) or non-invasive ventilation (via a mask
or mouthpiece, for example); however, the illustrations and text describe
mask setups only.
1.1 Definitions
This manual contains special terms and icons that appear in the margins
to draw your attention to specific and important information.
CAUTION
Explains special measures for the safe and effective use of the
device.
WARNING
Alerts you to possible injury.
Note: Is an informative or helpful note.
: Signals an action for you to perform.
1.2 User/Owner responsibility
The owner or user of this device shall have sole responsibility and liability
for any injury to persons or damage to property resulting from:
•The device being set up, operated or cleaned in a manner which does
not comply with the instructions provided
•The device being set up, maintained or altered by unauthorised
persons and/or in a manner which does not comply with the
instructions.

1.3 Medical information
Purpose of your ventilation device
The VS III is intended to ventilate both adults and children. Patients may
use it at home and/or in a hospital.
The device is used with either a single or double respiratory circuit.
Two ventilation programs can be set up by your physician. You can
switch from one to the other while ventilation is running.
Warnings
•This manual must be read and understood in full before the device is
used.
•The advice contained in this manual does not replace the instructions
given by your prescribing physician (or HME provider), who will
already be familiar with the operation of the device through the
clinical manual provided.
•The device settings must be entered by competent and trained staff
under the supervision of a physician.
•The device must be used with the accessories recommended by the
manufacturer and by your prescribing physician. The use of
inappropriate accessories is likely to affect the operation of the
device.
•If you have any questions about setting up, operating or maintaining
your ventilator or its accessories, contact your HME provider.
•The ventilator must be transported in its travel bag.
•In the case of externally visible faults, cease using the device.
•If the performance of the device becomes erratic, and you find it
difficult to breathe or trigger a breath, contact your HME provider.
•To avoid the risk of electrocution, do not open the device casing.
Repairs and internal servicing should only be performed by an
authorised service agent.
•If there is interference on the electrical network, operate the
ventilator on battery power.
•Your HME provider must ascertain the electromagnetic
characteristics of the environment in which this ventilator will be
used. In particular, your HME provider must ensure that:
•When the ventilator is operated in proximity to other electrical
devices, including cell phones, there is no interference, and the
ventilator performs correctly
•The ventilator is never placed on or under other devices

3
Description of the device
•There is an adequate distance between the ventilator and other
electrical devices in your home.
•In accordance with Directive 2002/96/EC concerning waste electrical
and electronic equipment, this ventilator must be sorted and
disposed of separately from other types of rubbish. It must not be
disposed of with ordinary municipal waste. Contact your HME
provider for more information.
The above are general warnings. Other specific warnings and notes will
be found throughout the text of the manual.

2.3 Respiratory circuit
According to the ventilation mode prescribed by your physician, you will
be using one of the following:
•A single circuit
•A single circuit with expiratory valve and with or without a pressure
line
•A double circuit.
To determine the type of respiratory circuit prescribed for you and for
instructions on connecting it to the device, see “Connecting the
respiratory circuit” on page 9.
3 Connection procedures
The device must be placed on a flat surface. Ensure the area is dust-free,
and cleared of any objects that could block the dust filter.
CAUTION
Be careful not to place the device where it could be knocked over
or where someone is likely to trip over the power cord.

3.1 Connecting to a power supply
To connect the ventilator to mains power:
1. Plug the power supply connector into the rear of the ventilator (into
the socket marked , see next figure) .
2. Plug the power cord into the power supply box and fasten to
prevent accidental disconnection .
3. Connect the other end of the power cord to the mains .
Figure 7: Connecting the device to the mains power supply
Note: Skip step 2 if using a power supply unit with a fixed power cord.
Your device is now in standby mode.
WARNING
The power cord is equipped with a push-pull locking connector.
Gently pull the power cord to remove from the ventilator. Do not
twist its outer housing.
Notes:
If your device is fitted with a rechargeable internal battery it can be used
without a mains power supply for a period of 2–4 hours, depending on
your settings.
The battery recharges automatically when the device is connected to
the mains supply.

Connection procedures
3.2 Connecting the respiratory circuit
CAUTION
Only the circuit supplied by your HME provider may be used with
your device. Using a different type of circuit may reduce the
effectiveness of your treatment.
Option 1 – Single circuit
1. Connect one end of the corrugated tube firmly to the air outlet, as
shown in the next figure :
Figure 8: Connecting a single circuit to the device
Once your circuit is connected to the device, you can connect the mask
to the other end of the tube.
Option 2 – Single circuit with expiratory valve and
pressure line
1. Connect the air outlet firmly to one branch of the corrugated
tube .
2. Connect the expiratory valve tube (the only one fitted with a
white connector) to the valve control , then turn the connector
slightly to the right to make the connection secure.
3. Finally, connect the other tube (with no connector fitted) to the
pressure line .
Note: If your circuit configuration does not include a pressure line,
this third step will not apply.
