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 ventilation via a mask or by tracheotomy tube; 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: Operation which is not in accordance with the operating instructions supplied • Maintenance or modifications carried out unless in accordance with authorised instructions and by authorised persons. •

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 limb or a double limb respiratory circuit.

Introduction

1

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 or your prescribing physician. The use of inappropriate accessories is likely to affect the operation of the device. In the case of externally visible faults, cease using the device. In the event of functional problems (e.g. you find it difficult to breathe or trigger an inspiratory phase), contact your HME provider. Do not open the device casing. Repairs and internal servicing should only be performed by an authorised service agent.

The above are general warnings. Other specific warnings and notes will be found throughout the text of the manual.

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 1. Plug the power cord into the rear of the device (see next figure). 2. Plug one end of the mains power cord into the power box 3. Plug the other end of the cord into the mains power supply

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 :

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.
