SAFETY PRECAUTIONS
In General Control Unit
Do not use this equipment in the
presence of flammable anaesthetics.
Keep away from sources of heat and
naked flames.
Bed frames used with the systems
can vary greatly depending on the specific
healthcare setting (i.e. hospitals, nursing
homes, home care etc). It is the responsibility
of the carer to carry out the necessary risk
assessments to ensure the safety of the
patient. This includes, but is not limited to,
the appropriate use of side rails to prevent
falls and/or patient entrapment.
Minimise articles (e.g. bedding) between
the mattress surface and patient, and secure
bed sheets loosely so as not to affect the
alternating cell movement.
The control unit is tested and CE marked
in line with Medical Device Directive (93/42/
EEC).
Only plug into a mains socket using the
mains cable supplied with the system.
Exposure of the control unit to any liquid
while it is plugged in could result in a severe
electrical hazard.
Only use fuses that have the same
specified rating. Using fuses with higher
ratings could result in damage and/or injury.
(See Technical Specification).
The control unit is a precision electronic
product. Use care when handling or
transporting. Dropping or other sudden
impacts may result in damage to the unit.
Do not open the control unit – risk of
electrical shock. Do not attempt to repair or
service the control unit. Repairs and service
should be conducted by suitably trained
personnel. If the control unit is not functioning
properly, or has been damaged, unplug the
unit and take it out of service immediately
(See contact information on rear cover for
repair and service information).
Do not place any objects or items, such
as blankets, on or over the control unit.

PRODUCT OVERVIEW
Alternating Mattress System (see Technical Specification)
The Plus II Dynamic Mattress Replacement
System is intended to provide comfort and
pressure relief to patients vulnerable to
pressure damage. It is designed for use on
both standard and profiling bed frames. Ideally,
patients allocated to this system will have
some degree of independent mobility or can be
repositioned according to individual needs.
The maximum patient weight limit is
177kg (28 Stone).
Mattress
This system includes three static head cells
to provide static support for optimum user
comfort, while air pressure in the other cells
is alternated over a 12 minute cycle. This
provides regular periods of pressure reduction
to aid blood and lymphatic flow to vulnerable
tissue
Control Unit
The control unit provides the air supply to the
mattress.
• It is controlled via a touch panel with
integrated digital display. The alarm sounds
when low pressure is detected or when
power is interrupted. The alarm mute
function silences the alarm for a maximum
of 20 minutes – the alarm resumes if the
cause of failure is not resolved. The alarm
will sound for up to two hours following an
interruption to power.
• The control unit includes a back up battery
for the audible alarm. This battery is
continuously re-charged and will last the life
time of the product.
• Functions on the control panel adjust the 8
comfort level settings.
• When a fault condition exists a warning LED
is illuminated with an audible alarm.
The visible and audible alarm function has a
number of indications depending on the cause
of the failure (see’Troubleshooting’ section).
If the mains cable becomes detached the
alternation sequence is suspended and the
mattress cells remain inflated and/or deflated
based on the current cycle. The audible alarm
will sound.

OPERATION
Mattress Function
Establishing Pressure (supine patient)
With the patient lying supine (face upwards),
use the ‘+/-’ functions to establish the best
setting for effective support and comfort.
Before changing or lowering the pressure,
ensure the system is working effectively by
performing a ‘bottoming out’ test.
Once the system has been set for the patient,
re-check after approximately 20-30 minutes to
ensure the patient is comfortable and that the
unit is functioning correctly.
Bottoming Out Test
When altering the pressure setting, ensure
the patient is not bottoming out (insufficiently
supported by the air cells).
1. Ensure the system is in alternation mode.
2. With the patient lying in a supine position,
unzip top cover just past the sacral
(buttocks) region.
3. Slide a hand along a deflated cell under the
patient’s sacral area. The inner static cell
will remain inflated but a hand should slide
easily between patient and static cell.
4. If a hand can pass under the sacral area the
patient is adequately supported and
pressure can be lowered as required.
5. Repeat bottoming out test if pressure has
been lowered.
Establishing Pressure (upright
position)
When moving the patient to a sitting or more
upright position, the pressure may need to be
increased to provide added support and to
avoid bottoming out.
It is important to return to the original
pressure setting when the patient returns to
the supine position.
Wait a minimum of 12 minutes between
pressure adjustment and patient assessment,
it may take a full cycle for the system to
adjust.
CPR Function
Rapid deflation of the mattress may be required
for emergency treatment or system deflation.
Firmly pull the release CPR tag from the side of
the mattress to rapidly deflate the entire system.
To re-inflate the system after the CPR tag has
been pulled, replace the CPR tag ensuring all
sealing connectors are firmly attached (see
image opposite) and restart the control unit.
Wait for the mattress system to reach optimal
pressure.
A bottoming out test must be performed
after mattress inflation, following rapid
deflation.
Re-inflation settings could be different
to setting prior to deflation. Ensure correct
pressure setting is selected.
10
OPERATION
To gain access to the sealing connectors,
unzip the top cover past the CPR tag.
Push together keeping both halves
parallel to each other.

Use of Incontinence Products
Incontinence products such as sheets or
pads can be used with this system. However,
product performance is likely to reduce due
to the patient experiencing less pressure relief
when using these aids.
If incontinence products are to be used it
is recommended that regular patient skin
checks are performed to ensure skin integrity is
maintained.
Static Mode
Patients should always be nursed on the
mattress in alternating mode but the static
mode maybe selected for short intervals if
a patient is finding it difficult to tolerate the
alternating mode. (This could occur if, for
example, the patient is in pain, nauseated or
perhaps having difficulty in getting off to sleep).
When static is selected all cells inflate at the
pressure at which the mattress is set, thereby
offering a non moving surface. The digital
control system will return to alternating mode
after one hour, if not manually selected by the
user. This is a safety mechanism to ensure
patients are not left on a constantly inflated
surface. It should be used only after assessing
the risk to the patient’s skin.
To select static mode depress the ‘A/S’ button,
the static LED will illuminate. The pressure can be
adjusted to suit using the pressure adjustment
‘+/-’ functions on the front of the control unit.

CLEANING
Infection Control
Routine cleaning for infection control must
be carried out in accordance with your local
infection control policy or regulatory body.
Cleaning the Control Unit
Disconnect the mains cable from the
power socket before attempting to clean the
control unit.
Do not immerse the power unit in water.
Ensure the mains cable and power unit
are dry before use.
The control unit can be cleaned by wiping
down with a damp cloth soaked in a sodium
hypochlorite solution (1000 ppm available
chlorine) and dried with a clean dry cloth.
The power unit is not IP rated therefore
care should be taken to ensure only a damp
cloth is used.
Cleaning the Mattress
Before attempting to clean the mattress the
top cover should be checked for physical signs
of damage that may lead to strike-through
(ingress of fluid through cover). This is achieved
by unzipping the top cover and looking for
signs of staining to the white underside. Any
evidence of strike-through will require a new
cover to be fitted to the system.
The cover must not be reused if strike-
through is evident.
Wipe down with a disposable soft cloth
moistened with a mild detergent and diluted in
warm water (40˚C), dry thoroughly before use.
Wipe down with a solution of Sodium
Hypochlorite or similar (up to 1,000ppm
Chlorine), dry thoroughly before use.
In extreme cases 10,000ppm Chlorine
can be used but the following process must
be adhered to: 1) Wipe cover down using
cold water 2) Clean with Chlorine solution 3)
Finally wipe cover again using cold water.
The top cover may also be decontaminated
using Ethylene Oxide or the Draeger method.
Additional infection control and routine cleaning
must be carried out in accordance with your
local infection control policy.
Do not use Phenol based cleaning agents (e.g.
Stericol, Hycoline, Clearsol etc.).
