Safety Warnings
•It is the responsibility of the care giver to ensure that the user can use this product
safely.
•Whilst the patient is unattended, safety sides should be used based on clinical
assessment and in line with local policy.
•Alignment of the bed frame, safety sides and the mattress should leave no gap
wide enough to entrap a patient's head or body, or to allow egress to occur in a
hazardous manner where entanglement with the mains power cable and tubeset or
air hoses may result. Care should be exercised to prevent occurrence of gaps by
compression or movement of the mattress. Death or serious injury may occur.
•Make sure that the mains power cable and tubeset or air hoses are positioned to
avoid causing a trip or other hazard, and are clear of moving bed mechanisms or
other possible entrapment areas. Where cable management flaps are provided
along the sides of the mattress, these should be used to cover the mains power
cable.
•Electrical equipment may be hazardous if misused. There are no user-serviceable
parts inside the pump. The pump's case must only be removed by authorised
technical personnel. No modification of this equipment is allowed.
•The mains power socket/plug must be accessible at all times. To disconnect the

About Nimbus 3 and Nimbus 3 Professional
Nimbus 3 and Nimbus 3 Professional are Dynamic
Flotation Systems for the prevention, treatment and
management of pressure ulcers.
Nimbus 3 and Nimbus 3 Professional systems comprise
a pump and mattress replacement which can be used on
standard hospital and normal domestic beds. Beds can
be adjusted or profiled with the mattress in position.
Nimbus 3 Professional mattress has the following
The
additional features to enable the patient to be proned,
and to assist with pressure area and patient care
management:
• A Head Section Deflate Control to allow the three
head cells to be fully deflated.

incorporate an advanced
AutoMatt® sensor pad which
makes sure that the patient is automatically supported at
optimum pressures regardless of size, height, position or
weight distribution.
If cardiac arrest occurs, the
Professional mattresses can be deflated in less than 10

Professional systems.
The pump comprises a moulded case with non-slip feet
on the base and rear, and an integral carry handle.
Nimbus 3 and Nimbus 3
The pump has two modes of operation:
•
Dynamic mode that cycles the support surface
beneath the patient every 10 minutes providing
periods of pressure relief for the whole body.
Static mode where the support surface remains
•
constant (all cells equally inflated).
The controls and indicators are located on the front
panel, and a sophisticated alarm system differentiates
between normal operation and genuine system faults. If
an alarm situation is detected a flashing indicator will
illuminate, together with an indication of the cause of
alarm, and an audible warning will sound.
The pump can be fixed to the foot end of a hospital bed
by the separate bed bracket. The bed bracket fits in the
pump handle and then clips onto most common bed
frames. The pump can also be stood on the floor, either
upright or on its rear cover.

CPR ControlThe CPR (Cardio-Pulmonary Resuscitation) Control is
at the foot end of the mattress, and allows the air to be
evacuated in under 10 seconds.
Transport ControlThe Transport Control is next to the CPR Control. When
operated, it seals the mattress so that air is not exhausted
when the tubeset is disconnected and also creates an
even pressure in all the cells.
TubesetThe tubeset incorporates a flexible, compact anti-kink
tube that is resistant to crushing and any subsequent
obstruction of air flow. Each end has a quick-lock
system for easily connecting and disconnecting the air
supply at the pump and mattress.

ContraindicationsDo not use
for patients with unstable spinal fractures.
CautionsIf 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
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 therapy (alternating) cushions may be unsuitable
for patients with poor sitting posture or pelvic 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.
Nimbus 3 and Nimbus 3 Professional systems
Nimbus 3 and Nimbus 3 Professional systems
The above are guidelines only and should not replace clinical judgement.
The
Nimbus 3 and Nimbus 3 Professional systems represent one aspect of a
pressure ulcer management strategy; if existing wounds do not improve or the
patients condition changes the overall therapy regimen should be reviewed by
the prescribing clinician.
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.

Patient Positioning Guidance for the Nimbus 3 Professional Mattress
Cell 4Head Section Cells
(1 - 3) Fully Inflated
Nimbus 3 Professional mattress allows the patient to be placed in either the
The
Supine or Prone positions.
WARNING
A full patient assessment, as to the suitability for Prone Nursing, is
essential before commencing the procedure.
Safety sides should be used where appropriate (Refer to “General
Safety” on page iii).
It is important that the p atient’ s head, neck and shoulders are in the
correct anatomical position.
Care should be taken at all times to check that all tubes/lines are
positioned correctly.
In the Prone position, regular checks should be made to make sure
the patient is free from a build up of pressure on the anatomically
sensitive areas such as:
• Head and facial areas including eyes
• Top of the shoulders
•Sternum
• Breasts and genitals
• Knees and toes
It is important for the optimal use of the system that patients are positioned
correctly on the mattress.
1.In both the Supine and Prone positions, patients
should be positioned on the mattress so that the tops
of their shoulders lie between the third and fourth
cells.
2.Supine Position.
21
3.Prone Position.
Cell 4
Head Section Cells
(1 - 3) Fully Deflated
4.It is recommended that a minimum of four staff will
be required to turn the patient from the Supine to
the Prone position.
• The anaesthetist or most senior member of the
team should be positioned at the head end of the
bed and will co-ordinate the turning procedure.
This person will also be responsible for the safety
of the patient’s head, neck and ventilation tubing.
• The other members of the team will help safeguard
all lines, and assist with the turning procedure as
directed.
Before commencing the turn, it is recommended that all non-essential lines
and monitoring equipment are disconnected.
5.With the patient in the Supine or Prone positions,
the mattress controls can be configured as follows:
• Set the Head Section Deflate Control to
Head Section Deflate (where the 3 Head cells are
fully deflated, and the Shoulder Support Cell is
fully inflated to support the patient’s shoulders)
which can assist with intubation and insertion of
central monitoring lines.
• Open individual Vent Valves (on the seven Torso
cells, four Thigh cells and five
Heelguard cells) to
allow single cell deflation to assist with pressure
area care and patient management, including
everyday interventions such as CXR imaging.
TriCell
Vent Valve Restrictions. For periods longer than 10 minutes, have
no more than 4 cells deflated at any one time (excluding the three
cells in the Head Section).

6.Decontamination
The following processes are recommended, but should be adapted to comply with
the local or national guidelines (Decontamination of Medical Devices) which may
apply within the Healthcare Facility or the country of use. If you are uncertain, you
should seek advice from your local Infection Control Specialist.
Nimbus 3 and Nimbus 3 Professional system should be routinely
The
decontaminated between patients and at regular intervals while in use; as is good
practice for all reusable medical devices.
WARNING
Remove the electrical supply to the pump by disconnecting the
mains power cord from the mains power supply before cleaning.
Protective clothing should always be worn when carrying out
decontamination procedures.
Caution
Do not use Phenol-based solutions or abrasive compounds or pads
during the decontamination process as these will damage the
surface coating. Do not boil or autoclave the cover.
Avoid immersing electrical parts in water during the cleaning
process. Do not spray cleaning solutions directly onto the pump.
To cleanClean all exposed surfaces and remove any organic
debris by wiping with a cloth moistened with a simple
(neutral) detergent and water. Dry thoroughly.
Chemical DisinfectionTo protect the integrity of the cover we recommend a
chlorine-releasing agent, such as sodium hypochlorite,
at a strength of 1,000ppm available chlorine (this may
vary from 250ppm to 10,000ppm depending on local
policy and contamination status).
Wipe all cleaned surfaces with the solution, rinse and
dry thoroughly.
Alcohol based disinfectants (maximum strength 70%)
may be used as an alternative.
Ensure the product is dry before storage.
If an alternative disinfectant is selected from the wide
variety available we recommend that suitability for use
is confirmed with the chemical supplier prior to use.
23
DO NOT WRING/MANGLE, AUTOCLAVE OR USE
PHENOLIC BASED SOLUTIONS.
Thermal DisinfectionFor information for the mattress top cover, including
laundering guidelines, refer to “Cover Specification” on
page 30.
