ABOUT YOUR MATTRESS
The OSKA Series6 features a
proprietary system of interconnected
air support cylinders designed to deliver
outstanding pressure redistribution for
those with or at risk of skin breakdown.
The OSKA Series6 is intended for use as
a non-powered reactive therapy surface,
or as a powered active therapy surface
via the addition of a powered air control
unit.
DESCRIPTION:
The system consists of a foam shell
with a high-density, zoned foam top
layer that serves as the interface
between the patient and the inner air
system. The foam shell also includes a
contoured Safety Edge™ foam bolster
design, providing added patient stability
and positioning. OSKA Series6 also
includes the unique Heel Slope® feature,
designed to further reduce pressure
for the vulnerable heel area. Within
the foam shell is housed the ination
system, consisting of air cylinders
running lengthwise within the mattress.
One of two different, optional add-on
powered control units can be connected
to the mattress to provide alternating
pressure or powered otation modes.
The system also includes an auto rm
mode to provide a rm support surface
for use during patient care and to assist
during patient transfer. Built-in check
valves ensure an ideal therapeutic
setting for non-powered pressure
redistribution when the control unit is
not attached.
INDICATIONS FOR USE:
The OSKA Series6 model is intended
as an aid in the prevention and
treatment of pressure ulcers. Powered
modes are intended for active wound
treatment, and may be indicated for
use as a preventive tool against further
complications associated with critically
ill patients or immobility.
1. Use this unit only for its intended
use and with recognised accessories
which are described in the operating
instructions; use of other accessories
or materials may degrade minimum
safety level.
2. Never operate the product’s
powered control unit if it has a

HOW TO SET UP YOUR
MATTRESS
1. Place the Series6 mattress on the bed
frame with the airline connectors at
the foot end of the bed. The mattress
has a black bottom cover that should
be placed directly on the bed frame,
the mattress cover will have airline
connecters on the bottom left corner,
make sure this matches with the
airline connecters on the mattress.
The blue top cover should face
upwards, with the foot icon at the
bottom of the bed frame.
2. Check the bed frame is appropriate
for use with the mattress, i.e. the
length and width of the mattress
are appropriate for the frame. Place
directly on a healthcare bedframe
only, never on top of another
mattress.
3. The mattress is now ready for use
in the non-powered mode (that is,
without the powered control unit
attached) by users who are within the
500 lbs. (226 kg) weight limit for the
product [400 lbs. (180 kg) in powered
mode].
4. The surface is designed to be used
with appropriate linens in place. See
page 14.
CONNECTING OPTIONAL POWERED
CONTROL UNIT:
1. Hang the control unit on the foot
board at the end of the bed using
fold-out hangers (gure a). Connect
airlines to control unit by pressing
quick connector into port on the
side of unit. “Triangle” symbol should
face front. (gure b) audible “click”
indicates secure connection.
NOTE: The hanger lock strip (included,
item # P10064, Fig. C) can be used to
help hold control unit more snugly in
place on thin footboards such as those
often found on home health care beds.
To use, place the strip in position around
the hanger hooks as shown in Figure D.
DESIGN FEATURES
1.
V-GUARDTM cover
with Shear Transfer
Zones ™
Outer cover features a bi-directional stretch fabric designed to allow full
integration of the user into the surface. Top is made from proprietary
polycarbonate-fortied healthcare fabric, which provides high resistance to
the damaging effects of diluted bleach and other aggressive cleaners and
disinfectants. It wipes clean easily with standard, hospital-grade cleaners. It
has a low moisture vapour transmission rate (MVTR).
Patented “Shear Transfer Zones” incorporated beneath top fabric creates
shear-minimizing bands beneath heels, sacrum and scapula. Zones help
prevent these bony prominences from digging into the surface, while
protecting against the damaging effects of micro shear, macro shear, and
rotational (pivot-induced) shear. Design also helps
“glide” the user back to their original position following HOB elevation.
Exclusive split bottom design helps reduce sliding of mattress while also
reducing the “gatching noise” typical of non-slip fabrics.
2.
Foam shell with
Geo-Matt® top
surface
The clinically proven Geo-Matt® segmented design incorporated into the top
surface of the mattress is a high-density, medical grade foam. The unique
geometric design consists of over 800 individual cells, each of which acts
individually to redistribute pressure, to reduce heat and moisture build-up
on the skin, and to reduce shear to underlying tissues. This foam topper is
approximately 2” in height and tapered at the foot end of the mattress. The
unique Heel Slope® feature helps further reduce interface pressures on
vulnerable heels.
3.
Safety Edge™
bolster system
The supportive Safety Edge™ consists of engineered inner and outer foam
bolsters for added patient stability in sitting and lying down.
4.
Proprietary air
cylinder system
The air system consists of four interconnected support cylinders arranged
longitudinally (head-to-foot) and constructed from RF- (radio-frequency)
welded urethane. The system is designed to provide and maintain low
interface pressures throughout the mattress in the non-powered mode.
When the powered control unit is attached, it provides active therapy in the
alternating pressure mode via ination and deation in a xed 10-minute
cycle. The system requires no adjustment or maintenance for the ve-year
duration of its warranty.
5.
Control Unit
options:
Model 5900 Digital Control Unit. Model 5500 Standard Control Unit.

WARNING!
The t of the mattress to
the bed frame is important.
Minimizing spaces or gaps
between the mattress and
frame will help prevent patient
entrapment issues.

2. Connect the ends of the air lines
with two right angle male connectors
(Figure E) to the ports on the side
of the mattress. Ports are located
beneath a fabric ap near the right
corner at the foot of the mattress.
Ensure that the air lines are not kinked
or twisted. Press connectors into
ports until you hear an audible “click”
for each. Press ap closed.
3. Ensure that green On/Off switch
at side of control unit is “Off”. Plug
power cord into wall outlet. Press On/
Off switch “ON”.
Figure C Figure D
4. When power switch is turned to
ON, the unit will power up in “Auto
Firm” mode and begin performing a
system check. This lls the air system
completely, in order to conrm the
proper connection and function of
both the mattress and the control
unit prior to a patient being placed
on the surface. If the mattress is
completely empty of air, this can take
as long as 20 minutes. You must leave
the mattress for a full 20 minutes to
fully inate before using or trying to
change the comfort level setting.
5. System will remain in “Auto Firm”
mode until this process is complete.
“Low Pressure” indicator light and
audible alarm will remain on as well.
Audible Alarm can be disengaged
during this process by pressing the
Audible Alarm On/Off button.
6. When system check is complete, the
control unit will revert to previous
comfort setting and “Alternate” mode.
Low Pressure indicator light will turn
off. System is now ready to be set for
the next user.
NOTE: If “Low Pressure” remains on
after 30 minutes, call for service.
Do not connect the power
cord to an extension cord or
to a multiple outlet strip. If
the use of extension cords or
multiple outlet strips cannot be
avoided, use only heavy duty or
hospital-grade connectors that
Do not cover the power cord
with a rug or carpet. Rugs or
carpets can prevent normal air
ow, which can lead to greater
heat built-up. Place the cord in
a low or no trafc area. Check
to be sure the motion of the
bed does not interfere with the
bed’s power cord or plug.
WARNING!
To avoid potential for injury to
patient’s foot, the control unit
should be positioned such the
hangers remain ush to the
headboard and do not extend
on to the sleep surface. This
may require use of the hanger
lock strip. See NOTE above.
Figure E
CAUTION!
Do not cut air lines to increase
separation. If additional
separation is needed to connect
air lines to the mattress, gently
pull air lines away from one
another to lengthen the split.
CAUTION!
Never thread air line through
mechanical parts of the bed
or bed rails where normal bed
movement may damage the air
lines or the air control unit itself.
Check to be sure the motion of
the bed does not interfere with
the air lines.
WARNING!
Always plug the power cable
securely into the wall outlet.
Make sure the wall-mounted
outlet will accommodate a
heavy duty or hospital-grade
plug and that the outlet is in
good working order. The plug
of the power cord should t
tightly into the wall outlet.
The plug body, the wall outlet,
and the wall plate should not
be cracked or chipped. The
plug blades should be securely
retained in the plug body. The
ground pin of the plug should
be intact and secure.
are approved by the facility.
Multiple outlet strips should
be mounted on a xed object
to reduce the risk of liquid
spills and physical damage. In
addition, if multiple-receptacle
outlet boxes are used, they
also should be protected from
the risk of liquid spills and
physical damage. All extension
cords and multiple outlet
strips should be tagged and
inspected routinely.

DIRECTIONS FOR POWERED USE
WEIGHT LEVEL SELECTION
Use the +/- buttons to set according to
the patient’s weight. Use the chart on
the front of the pump to select the right
setting.
MODE SELECTION: PRESS BUTTON TO
SELECT “ALTERNATE”, “FLOAT”, OR
“AUTO FIRM”.
“ALTERNATE” MODE:
Creates an “A-B” sequence of ination
and deation of the mattress’s four air
cylinders designed to change loading
across the surface in a 10-minute
cycle. In this mode, air cylinders 1 and
3 inate while 2 and 4 deate. After
approximately 5 minutes, the pattern
reverses.
“FLOAT” (POWERED FLOTATION
THERAPY) MODE:
Suspends cyclical ination/deation of
the air cylinders and instead provides
powered otation therapy. In this mode,
all four air cylinders are evenly inated,
and the system maintains ideal pressure
management by adjusting in response
to any repositioning of the user on the
surface.
“AUTO FIRM” MODE:
Suspends cyclical ination/deation and
sets system to rmest ination level for
20 minutes to facilitate user transfer,
feeding, dressing changes, and other
activities of daily living (ADLs), and CPR.
After 20 minutes, system will revert to
previous comfort setting and “Alternate”
mode.
POWER FAILURE AND LOW PRESSURE
ALARMS:
AUDIBLE ALARM ON/OFF: When
indicator light is on, an audible alarm
will sound if either the Low Pressure or
Power Failure indicator light is on. Press
button to silence the alarm. Alarm can
also be toggled off in advance if audible
alarm is not desired for low pressure
conditions.
POWER FAILURE:
During power failure situation or
upon power down, the Power Failure
indicator light will come on and the
audible alarm will sound. Press the mute
button to silence the alarm. (See “Power
Interruption”, below.)
LOW PRESSURE:
If “Low Pressure” indicator light comes
on after initial set-up or when moving
mattress or control unit, rst check that
all air lines are properly connected and
that they are not kinked. If light is still on
after 30 minutes, call for service.
REMOVING CONTROL UNIT:
To ensure effective non-powered
performance, DO NOT leave the control
unit attached to the OSKA Series6
mattress when powered operation is
no longer desired. Instead, disconnect
the control unit from the air ports at the
mattress. This will allow the air system to
reset to its ideal, non-powered ination
level.
POWER INTERRUPTION:
The OSKA Series6 is designed to
eliminate concerns related to loss
of power. In the event of a power
interruption during powered use, the
system will maintain a safe level of
patient support. However, to maximise
patient support and comfort during
power interruptions, simply disconnect
the mattress air lines at the control
unit, or at the mattress port. In either
case, the air system in the mattress will
reset to its ideal non-powered ination
level.
PATIENT TRANSPORT:
The OSKA Series6 is designed to
facilitate patient transport. For transport
when the powered control unit is in use,
simply disconnect the air lines from the
control unit and reconnect when patient
has reached destination. In the non-
powered mode, no action is required.
NOTE: Transport cap is not intended for
use with OSKA Series6
HEAD-OF-BED ELEVATION:
All support surfaces using air as a
support medium are designed for
distributing pressures over the body
in a at, horizontal position. Bending
the support surface and the body at
the midpoint when elevating the HOB
concentrates the body weight over
WARNING!
DO NOT MOVE USER ON
MATTRESS ONLY. Mattress
should not be used alone for
user/patient transport.

14 oska.uk.com | 0845 381 0600 oska.uk.com | 0845 381 0600 15
and state laws/guidelines, and by
individual facility protocol. It is the
responsibility of the facility to be in
compliance with these laws, which
typically require that decisions on the
use of bed rails of any type are based on
assessment of the physical and mental
status of each patient individually. If
bed-rails are needed by the patient to
prevent fall-related injury, as determined
by this facility assessment, we
recommend that the bed-rails be locked
in the up position at all times. We do
not require use of bed-rails unless the
patient is deemed to be safer with them
than without them.
CPR:
The Standards for Life Support
recommended by the American Heart
Association suggests a hard level
surface for performing CPR. This
means moving the person to the oor if
possible. If that is not possible, do the
following: For performing CPR:
1. Press “Auto Firm” Button
2. Place a crash board beneath the
patient.
3. Follow CPR procedures.
STORAGE AND TRANSPORTATION:
Store the mattresses in a clean, dry
the centre of the surface, stressing that
small area. This extreme change in
dynamics creates a challenge for all air
support surfaces. Maximum pressure
management benets are realized
between zero and 30° HOB elevation.
Beyond 30°, the amplitude of the
changes in the air cylinders begins to
decrease in proportion to the increased
elevation of the HOB. Although the
mattress will maintain its support and
therapeutic capabilities up to and
including 70° HOB, for maximum benet
we recommend that any pressure
management surface be used with the
head of the bed elevated as little as
possible, and for limited periods at a
time.
ELECTROMAGNETIC OR OTHER
INTERFERENCE
This equipment generates, uses and can
radiate radio frequency energy and, if
not installed and used in accordance
with the instructions, may cause harmful
interference to other devices in the
vicinity. However, there is no guarantee
that interference will not occur in a
particular installation.
If this equipment does cause harmful
interference to other devices, which can
be determined by turning the equipment
off and on, the user is encouraged to
try to correct the interference by one or
more of the following measures:
- Reorient or relocate the receiving
device.
- Increase the separation between the
equipment.
- Connect the equipment into an outlet
on a circuit different from that to which
the other device(s) are connected.
- Consult the manufacturer for help.
TROUBLESHOOTING/PATIENT
COMPLAINTS:
Occasionally a patient may complain
of feeling as if he/she is “sinking into a
hole”.
1) This may occur when the head of the
bed is elevated and the mattress is
in alternating pressure mode. This
sensation is a combination of the
deation of the cylinders during their
cycle and the increased weight of
the patient on the sacrum and pelvis
when the head of the bed is elevated.
This demonstrates the need to
minimize elevation of the head of the
bed, or to select alternating pressure
mode if HOB elevation is necessary.
2) A patient may complain when he/
she is supine or side-lying and are
not used to the changing pressures
within the air system. Reassure the
patient that this is normal functioning,
as the cylinders alternately inate
and vent. The vented tubes are not
fully deated. Some air is always
maintained in them to prevent
bottoming out. After reassurance,
patients typically become acclimated
to the changing pressures.
GENERAL DIRECTIONS
BED LINENS:
Seven-inch deep tted sheets are
recommended. Multiple layering of linens
or underpads beneath the patient should
be avoided for the prevention and
treatment of pressure ulcers.
BED RAILS:
Due to concerns over the possibility of
patient entrapment, OSKA recognises
that the use of rails of any length is a
matter currently addressed by federal
CAUTION!
Be careful not to puncture the
mattress with needles or sharp
instruments. This may result in
loss of integrity of the cover or
internal air system. Regularly
inspect the mattress cover for
cuts, rips, cracks or tears.
Do not use the mattress if the
cover is damaged.
place. Once the mattress is removed
from the box, store in a at position if
possible. Protect from damage. Avoid
temperature extremes (below freezing
or above 120° F/50° C). Allow to
acclimate to room temperature before
use. Do no stack more than 10 high. Do
not stack other equipment on top of the
mattresses.
Store and transport control units in
a clean, dry place, protected from
accidental damage or falls. Avoid
temperature extremes (below freezing
or above 120° F/50° C); suggested
storage and transportation temperature
60° to 120° F (15~50° C), humidity

USE IN WOUND CARE:
Use of the OSKA Series6 is only one
element of care in the prevention and
treatment of pressure ulcers. Frequent
repositioning, proper care, routine skin
assessment, wound treatment and
proper nutrition are but a few of the
elements required in the prevention
and treatment of pressure ulcers.
As there are many factors that may
inuence the development of a pressure
ulcer for each individual, the ultimate
responsibility in the prevention and
treatment of pressure ulcers is with the
health care professional.
CLEANING.
V-GUARDTM CLEANING AND
AFTERCARE GUIDELINES.
OSKA V-GUARDTM technology covers
are durable but, as medical devices,
they need treating with great care. The
surface is vapour permeable so it is
waterproof, but breathable to reduce
sweating of patient. This outer barrier
must not be penetrated. Even the
smallest breach of this barrier will cause
uid to penetrate the mattress.
There are specic cleaning and care
instructions that need to be strictly
adhered to prolong the life of the
product.
GENERAL GUIDELINES
Do not puncture the mattress with
needles or sharp instruments. This may
result in loss of integrity of the mattress
air system and will void the warranty.
Inspect the covers and zipper area for
signs of damage, puncture, or wear
that could result in uid pass-through.
If the cover is stained, soiled, or torn,
inspect the internal components for
signs of contamination. If contamination
is evident, quarantine the mattress and
remove from service following infection
control procedures.
The air control unit should be dusted
every 30 days and cleaned with a damp
cloth and mild detergent.
AIR FILTER PREVENTIVE
MAINTENANCE:
The air lter for the Control Unit
should be checked routinely for signs of
dirt or contamination.
The frequency for cleaning depends on
the air quality. The air lter is accessible
from the backside of the Control Unit.
As the lter is white, the need to clean
is obvious. Simply turn the controller
off and remove the plastic cover,
remove the lter, and hand wash using
warm water and mild detergent. Rinse
thoroughly and allow to air dry. Replace
the lter and the plastic cover.
DELAMINATION:
Delamination is when the layers within
the structure of the mattress cover
separate. This can be caused by using
incorrect chemicals or too high a
concentrate of cleaning chemicals on
the surface.
HOW TO PREVENT DELAMINATION:
OSKA V-GUARDTM Technology covers
incorporate a special layering system
to make them much more resistant to
delamination than many other mattress
covers. However, to help prevent
delamination:
1. Always abide by the cleaning
instructions
2. Avoid using chemicals with too high
concentration.
3. Ensure cleaning chemicals are always
thoroughly rinsed off before allowing
to dry
4. The V-GUARDTM covers can tolerate
up to 10,000ppm chlorine but using
a weaker solution of 1,000ppm will
reduce the risk of a high concentrate
being left on the surface
5. Ensure the covers are thoroughly dry
before using or storing the mattress
Abrasive cleaning agents should
NOT be used.
In addition, due to the range
of cleaning chemicals and
conditioners being used, customers
should ascertain that any fabric
performs as expected, without any
adverse effect.
Some surface wrinkling may result
from cleaning procedures. This
1.1
1.2
1.3
should have no adverse effect on
the fabric’s properties.
If customers have their own
particular cleaning methods that
must be used and that are not
covered in this article, they should
consult OSKA for further direction
and guidance.
All polyurethane coatings need to
be treated with care when cleaning
the surface. Many industrial
cleaning agents are extremely
harsh on the coating and can cause
it to break down.
For supercial dirt use a disposable
wipe and a warm solution of
neutral detergent. Do not use
abrasive cleaners.
Disinfect in situ using 0.1% sodium
hypochlorite solution (1000ppm
available chlorine). Wipe off
any residue with clean water.
V-GUARDTM covers can tolerate
10,000ppm chlorine but using
a weaker solution of 1,000 ppm
will reduce the risk of a high
concentrate being left on the
surface.
The fabrics are able to be washed
in warm soap water at up to 95°C.
All cleaning agents and
disinfectants must be thoroughly
rinsed off and the item dried before
storage.
Spin and tumble dry on a low
setting (not more than 130°c. The
fabric surface may wrinkle but
this will not impede function). The
operator ensures it is removed as
soon as all moisture is removed.
The fabric must not be left sitting
on the heated bowl of the drier
when drying is complete.
Do not mangle.
Do not iron.
Store in a cool dry area.
Avoid excessive pressure and
always thoroughly dry fabric before
re-use or storage. Do not fold away
wet or store in damp conditions.
Keep away from sharp objects.
Regularly check the inside of the
cover for any signs of leakage
If the cover leaks then the
waterproof barrier has been
broken and a new cover should be
purchased from OSKA

STRIKETHROUGH:
Strikethrough occurs when the bres
in the mattress covers start to break
down. Small cracks develop, which on
inspection, may not be visible. This
means uids and other contaminates
can pass through the cover and
contaminate the core of the mattress.
HOW TO PREVENT STRIKETHROUGH:
Covers are most susceptible to
strikethrough damage when they are
wet. During cleaning, extra care should
be taken to avoid abrasion of the
surface. OSKA V-GUARDTM Technology
covers incorporate a special layering
system to make them much more
durable than many other mattress
covers. However, to help prevent
strikethrough:
1. Always abide by the cleaning
instructions
2. Avoid using chemicals with too high
concentration.
3. Ensure cleaning chemicals are always
thoroughly rinsed off before allowing
to dry
4. The V-GUARDTM covers can tolerate
up to 10,000ppm chlorine but using
a weaker solution of 1,000ppm will
reduce the risk of a high concentrate
being left on the surface
5. Ensure the covers are thoroughly dry
before using or storing the mattress
ROUTINE INSPECTION OF POWER
CORDS AND SAFETY TIPS TO
PREVENT FIRES
1. Assure that the electrical resistance
of the safety ground conductor
and the level of leakage current
(line conductor-to-safety ground
and neutral conductor-to-safety
ground) meet applicable standards
for resistivity and leakage current.
Protection afforded by the ground
pin is negated if the receptacle is
not properly grounded. If you have
questions about the adequacy of
your facility’s building wiring, contact
a qualied electrician or consult the
code authority in your jurisdiction.
2. Check all electrical outlets, including
accessory outlets for cleanliness,
physical integrity and functionality.
The IEEE standard 602-1996, section
4.2.2 advises that hospital-grade
outlets be used and that they should
be mounted with the ground pin or
neutral blade up to assure that any
metal that may drop between the
plug and the wall will most likely
contact an unenergized blade.
3. Check the power cord to assure that
contact pins are straight and secure
4. Routinely inspect the power cord for
damage sustained from crushing,
pinching, shearing, cutting, or from
being worn through. They can
be damaged by bed movement,
deterioration from use or aging, or
human or equipment trafc. The
cord’s insulation should be intact
and there should be no evidence
of bulging, stretching, crimping,
cracking, or discoloration, especially
at the ends, where the cord is
attached to the plug body and the
control unit.
5. Regularly inspect all parts of the bed
frame, motor, mattress and controller,
and the oor beneath and near the
bed for build-up of dust and lint.
6. Inspect the cover of the control panel
to assure that the covering is not
cracked or damaged, allowing liquids
or other conductive material to
penetrate to the switches.
7. Report any unusual sounds, burning
odours, or anything unusual to
maintenance personnel. Discontinue
use of the power cord immediately
and contact OSKA for replacement.
MATTRESS
Inspect the covers and zipper area for
signs of damage, puncture, or wear
that could result in uid pass-through.
If the cover is stained, soiled, or torn,
inspect the internal components for
signs of contamination. If contamination
is evident, quarantine the mattress and
remove from service following infection
control procedures.
You may use the Preventive Maintenance
Log provided on page 27 of this manual
to monitor and document regular
inspection and maintenance of your
OSKA Surfaces.
EMC
Electric devices may interact due
to electro-magnetic radiation. We
recommend a safety distance of at
least one meter, especially for sensitive
equipment.
Upon request, we will provide you with a
table for more detailed information.
