Clinical ~~~lications ...

Indications

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.

Contraindications

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.

Installation ;C$

x

m

The system is very simple to set up and the following guidelines may assist you. Preparing the Aura Cushion and Pump

1. Remove the contents of the packaging. You should have the following items: • Seat cushion • Cover • Pump 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 cushion. 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.

Cautions • 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.

4

6. Secure the Aura cushion to the chair by using the fixing straps as shown in the following illustrations. 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 shown below.

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 Aura cushion. 5

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 inflate fully. 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. ~..
