1. Introduction
About this Manual This manual is your introduction to the Auto Logic Dual
Mode support systems and the Aura Logic®seat
cushion. You must read and fully understand this
manual before using the system.
Use this manual to initially set up the mattress or seat
cushion, keep it as a reference for day-to-day routines
and as a guide to maintenance.
If you have any difficulties in setting-up or using the
Auto Logic and Aura Logic systems, contact your
ArjoHuntleigh sales office, listed at the end of this
manual.
Intended Use The intended use of this product is to prevent and/or
manage pressure ulcers for patients up to 200 kg
(440 lb).
The Auto Logic system should be used as part of a
prescribed plan of care (refer to “Indications” on
page 6).
About Auto Logic The Auto Logic systems comprise a mattress
replacement, overlay or seat cushion, all operated by the
same pump. The pump incorporates Self Set
Technology (SST), which adjusts air pressure every
10 minutes for the Active (Alternating) mode and
20 minutes for the Reactive (Constant Lower Pressure)
(CLP) mode to suit the Body Mass Index (BMI) and
positionof thepatient.Both supportsystemscan beused
on standard hospital beds.
A full technical description of the Auto Logic system
can be found in the Service Manual, part number
SER0006, available from your ArjoHuntleigh sales
office.
Auto Logic Pump The Auto Logic pump comprises a moulded case with
non slip feet on the base and rear and integral hanging
brackets.
The controls are situated on the top of the pump and a
sophisticated alarm system differentiates between
normal operation and genuine system faults. If an alarm
situation is detected an indicator illuminates on the top
and front of the pump and an audible warning sounds.
The Autofirm system, once activated, creates a
temporary firm surface to allow nursing procedures to
be performed.

Detachable Cover The standardcovercomprises a 2-waystretchPU coated
knitted fabric zipped to a durable polyester base. The
zips are protected by flaps to prevent ingress of
contaminants and allow easy removal of the cover for
cleaning.
Alternative covers with advanced properties, such as
Glide IS2and Ventilate IS2are also available (Refer to
“COVER SPECIFICATION” on page 30).
Cells The mattress comprises 20 polyurethane (PU) cells
providing support to the user in either Active
(Alternating) or Reactive (Constant Lower Pressure)
modes. The cells are slightly curved to reduce patient
movement down the mattress.
The side supporting cells incorporate Cell-in-Cell
technology to help the transfer of patients on and off the
bed by keeping the edges of the mattress firm.
Micro Air Loss System A micro air loss system is incorporated into the base
cover which de-humidifies the air surrounding the cells
to reduce heat build up within the mattress and ensure
patient comfort. This system is separate from the cell
inflation to enable both micro air loss and patient
transport modes to be incorporated into the mattress.
CPR Function A CPR (Cardio-Pulmonary Resuscitation) control is
positioned at the head end of the mattress to enable the
air to be evacuated in under 10 seconds.
Tubeset The tubeset has a 3-way pneumatic connection which
incorporates a flexible, compact anti-kink tube that is
resistant to crushing and any subsequent obstruction of
air flow.
If the tubeset is disconnected from the pump, the
mattress automatically changes to Transport mode.
Overlay Base Cover The base cover for the mattress overlay is PU coated
polyester on the underside. Four corner retention straps
are incorporated, which slide under the corners of the
base mattress.

Auto Logic 175 & 200 Mattress Replacement
The Auto Logic 175 & 200 mattress replacements are of
a similar construction to the overlay with the addition of
a non-slip base. Within the non-slip base, the 175
mattress includes a foam underlay and the 200 mattress
has an air filled zoned sub-mattress both of which
replace the need for a mattress on the bed. The base can
be removed to convert the mattress replacement to an
overlay, refer to ArjoHuntleigh for more information.
Air Sub-Mattress
(200 Only) The Sub-Mattress provides an integral constant pressure
support which removes the need for a standard mattress.
The pressure in the central zone of the pad is
automatically adjusted in line with the Active
(Alternating)/Reactive (Constant Lower Pressure)
(CLP) of the mattress. The pressure in the perimeter
zone of the pad is maintained at a higher level to help
transfer of patients on and off the bed.
On the underside of the Sub-Mattress there are eight
straps to attach the mattress replacement to the bed
frame. The straps can be moved to any of the 10 anchor
points to allow attachment of the mattress to different
bed frames.

2. Clinical Applications
Indications The Auto Logic systems are indicated for the prevention
and/or management of all categories1of pressure ulcer,
when combined with an individualised, comprehensive
pressure ulcer protocol: for example, repositioning,
nutritional support, skin care. Selection should be based
upon a holistic assessment of the patient’s individual
care needs.
These systems represent one aspect of a pressure ulcer
managementprotocol;allotheraspectsofcareshould be
considered by the prescribing clinician.
If existing wounds do not improve or the patient's
conditionchanges theoveralltherapyregimen shouldbe
reviewed by the prescribing clinician.
The above are guidelines only and should not replace
clinical judgement.
The Auto Logic mattress and cushion are designed for
patients weighing up to 200kg (440 lb).
Contraindications Do not use Auto Logicsystems for patients with unstable
spinal fractures.
Cautions If patients have other unstable fractures, or conditions
which may be complicated by a soft or moving surface,
advice should be sought from an appropriate clinician
before use.
While the Auto Logic systems have been designed to
manage patients up to the weight limits indicated above,
those approaching this upper limit are likely to have
additional care and mobility needs and may be better
suited to a specialist bariatric system.
Active (Alternating) therapy cushions may be
unsuitablefor patientswithpoorsitting postureorpelvic
deformity; advice from a seating specialist should be
sought.
Care of the Patient
When Sitting Seated patients are at increased risk of pressure ulcers
particularly if they are immobile or have wounds over
the seating area. For optimal outcome, provide a
pressure redistributing seat cushion in a chair which
promotes a good sitting posture and has a level base seat
to support the cushion, in addition to an individualised
repositioning programme.
Mattress and cushion combinations may have different upper weight limits.
Cushions should be used in combination with pressure-redistributing
mattresses to provide 24-hour therapy.
