Clinical ~~~lications ........
The Aura system is indicated for patients up to 120kg
and up to very high risk of developing pressure ulcers
and for all grades of pressure ulcers around the seating
area up to and including grade 4 (NPUAP, 1989)1.
The Aura system should not be used for patients with
unstable spinal fractures, or for patients who have a
poor sitting balance.
In the case ofpatients with other unstable fractures,
where a moving surface could be harmful, advice
should be obtained from the appropriate physician
before using the Aura system.
The Aura system is an aid to the prevention and management of
pressure ulcers. If there is no improvement in the patient s
condition, specialist advice should be sought.
The above are guidelines only and should not replace clinical
judgement or experience.

The system is very simple to set up and the following
guidelines may assist you.
1. Remove the contents of the packaging. You
should have the following items:
• Seat cushion
2. Plug the pump power cable into wall socket.
Do NOT switch the pump on.
3. The pump should be placed feet down on any
convenient horizontal surface or alternatively
suspended from the chair frame by means of the
spring loaded hanging hooks.
4. Check that there are no sharp objects on the
chair surface which may puncture the seat
5. Place the Aura cushion on top of the chair
surface. From a standing position in front of
the chair and f~9ing it, ensure 1!hat:
• the air feed tubes appear from the front right
comer of the cushion
• the cells are uppermost
• the cells are in a horizontal position across the
chair, NOT from front to back.
Do not use the seat cushion directly on the chair frame.
Always use the Aura cushion with the protective top cover.
Always use the seat cushion in correct orientation.
Avoid trailing cables-ensure that cables and tubing are
positioned beneath the chair to avoid causing a hazard.
• Ensure that the pump is placed safely under the chair or
securely attached to the arm of the chair by means of the
spring loaded hanging hooks.
6. Secure the Aura cushion to the chair by using
the fixing straps as shown in the following
7. If the chair is of the open sided construction,
then fix the cushion as shown below.
8. If the chair is. of the closed side type with a
removable seat cushion, fix the Aura cushion as
9. If the chair is of the closed side type with a
non-removable seat cushion, then security will
rely on the anti-slip pads on the base of the
10. Place the protective cover over the cushion and
zip up all round, taking care not to trap any
material in the zip.
11. Connect the air feed tube connectors to the air
outlet connectors on the pump unit, ensuring
that the tubes are not "kinked" or twisted.
Push the connectors in until they click.
12. Switch on the pump unit. All lights on the
front panel will momentarily flash; the
Run/Standby indicator will remain illuminated.
13. Allow approximately two minutes for the pad to
14. Adjust the comfort control as required.
Placing extra layers between the patient and the cushion
potentially reduces the benefits provided by the cushion and
should be avoided or kept to a minimum.
As part ofsensible pressure area care, it is advisable to avoid
wearing clothing which may cause areas oflocalised high
pressure due to creases, seams, etc. Placing objects in pockets
should be avoidedfor the same reason.
Controls, Indicators, and Alarms
This is situated on the side panel of the pump and is
used to activate the unit and reset the alarm. Mains
isolation sp.ould be performed by switching the pump to
standby ( 0 ) and then removing the mains plug from

In the event of low pressure in the seat cushion, the red
Low Pressure alarm indicator will start flashing and an
audible alarm will sound. The pitch of the alarm will
increase at 60 second intervals.
In the event of mains failure, the red alarm indicator
will start flashing and an audible alarm will sound.
The pitch of the alarm will increase~in time. If the
power supply is.refurned the audible alarm will stop,
but the alarm light will remain illuminated until the
system is reset.
When the cause of the alarm has been resolved, the
pump must be reset. This can be achieved by switching
the pump to Standby and back to Run using the
Run/Standby switch on the side panel.
Every time the pump is switched on all indicator lights
will illuminate for approximately two seconds. During
this period, the system self tests its circuits.
