GENERAL SAFETY Before you connect the system pump to a mains socket, read carefully all the installation instructions contained within this manual. The system has been designed to comply with regulatory safety standards including: • EN60601-1:1990/A13:1996 and IEC 60601-1:1988/A2:1995 • UL60601-1, UL2601-1 and CAN/CSA C22.2 No. 601.1-M90
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 pump completely from the electricity supply, remove the plug from the mains power socket. • The CPR control and/or the CPR indicator tag must be visible and accessible at all times. • Disconnect the pump from the mains power socket before cleaning and inspecting. • Keep the pump away from sources of liquids and do not immerse in water. • Do not use the pump in the presence of uncontained flammable liquids or gasses. • The cover of this product is vapour permeable but not air permeable and may present a suffocation risk. • Only the pump and mattress combination as indicated by ArjoHuntleigh should be used. The correct function of the product cannot be guaranteed if incorrect pump and mattress combinations are used. • To avoid the risk of electric shock, this equipment must only be connected to a supply mains with protective earth. • Due to the inherently lower flame retardancy of the high performance eVENT®1 fabric, it is NOT suitable for use in the homecare environment. Precautions For your own safety and the safety of the equipment, always take the following precautions: 1. eVENT® is a registered trademark of BHA Technologies Inc.
(iii)
• Placing extra layers between the patient and the mattress potentially reduces the benefits provided by the mattress and should be avoided or kept to a minimum. As part of sensible pressure area care, it is advisable to avoid wearing clothing which may cause areas of localised high pressure due to creases, seams, etc. Placing objects in pockets should be avoided for the same reason. • Do not expose the system, especially the mattress, to naked flames, such as cigarettes, etc. • In the event of a fire, a leak in the seat or mattress could propagate the fire. • Do not store the system in direct sunlight. • Do not use phenol-based solutions to clean the system. • Make sure the system is clean and dry prior to use or storage. • Never use sharp objects or electrically heated under blankets on or under the system. • Store the pump and mattress in the protective bags supplied.

1. Introduction About this Manual
This manual is your introduction to the Nimbus® 3 and Nimbus 3 Professional systems. Use it to initially set up the system, and keep it as a reference for day-to-day routines and as a guide to maintenance.
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. The Nimbus 3 Professional mattress has the following 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. • Individual Vent Valves to allow 16 of the 20 cells to be independently deflated. The Nimbus 3 and Nimbus 3 Professional mattresses 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 Nimbus 3 and Nimbus 3 Professional mattresses can be deflated in less than 10 seconds to allow cardiac resuscitation procedures to be performed.

Front Panel
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.

Detachable Cover
The standard protective cover comprises a 2-way stretch cover zipped to a durable anti-slip 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 Advantex® and eVENT®, are also available (Refer to “Cover Specification” on page 30).
Cells
The Nimbus 3 mattress comprises 20 polyurethane (PU) cells providing support to the user in either Alternating or Static modes. The cells are grouped in four sections, each of which has a specific function: • The three Head cells remain at a constant pressure for pillow stability and patient comfort. • The eight Torso cells combine alternating and static pressure characteristics to support patients fully in both lying and sitting positions without the risk of ‘bottoming’. • The four Thigh cells cycle dynamically to maximise pressure relief. • The five Heelguard® cells are specially powered to maximise the pressure relief under the heels. 3
AutoMatt
The advanced AutoMatt sensor pad is under the cells, and makes sure that the patient is automatically supported at optimum pressures regardless of size, height, position or weight distribution.
CPR Control
The 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 Control
The 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.
Tubeset
The 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.
Nimbus 3 Professional Mattress The Nimbus 3 Professional mattress is of similar construction to the Nimbus 3 mattress, with the addition of a Head Section Deflate Control, individual Vent Valves on 16 of the 20 cells and a Shoulder Support Cell. Detachable Cover

Head Section Deflate Control
Head Section Deflate Control
This is a two-position rotary-action control at the head end of the mattress: • Dynamic (Normal) Mode. The three cells in the Head Section are inflated at a constant pressure and the remaining 17 cells alternate. • TriCell Head Section Deflate. The three cells in the Head Section are fully deflated to assist with patient care management, and the Shoulder Support Cell (the fourth cell, next to the Head Section) is inflated to a constant pressure to support the patient’s shoulders. The remaining 16 cells alternate.
Cells
The Nimbus 3 Professional mattress has the same number of cells as the Nimbus 3 mattress (20 cells). The function of the first four cells at the head end of the mattress is different on the Nimbus 3 Professional: • The three cells in the Head Section are either fully inflated or fully deflated, depending on the position of the Head Deflate Control, to assist with patient care management. The cells are specially powered to enable them to be fully deflated. • The single Shoulder Support Cell (the fourth cell, next to the Head Section) has a shallow cutout in the mid-section of the cell. This is to allow access to the neck area for clinical procedures and to ensure the smooth, uniform extension of the neck during deflation. Its operation is controlled by the Head Section Deflate Control: the cell is either fully inflated to support the patient’s shoulders or alternates (together with the remaining 16 cells). • The remaining 16 cells (seven Torso cells, four Thigh cells and five Heelguard cells) have the same basic function as on the Nimbus 3 mattress.
Vent Valves
The seven Torso cells, four Thigh cells and five Heelguard cells have individual Vent Valves to allow each cell to be independently deflated, to assist with pressure area and patient care management.

2. Clinical Applications Indications
The Nimbus 3 and Nimbus 3 Professional systems are indicated for the prevention and management of all categories1 of pressure ulcer when combined with an individualised monitoring, repositioning and wound care programme. The Nimbus 3 and Nimbus 3 Professional mattress is designed for patients weighing up to 250 kg (550 lb). The Nimbus 3 and Nimbus 3 Professional cushion is designed for patients weighing up to 250 kg (550 lb).
Contraindications
Do not use Nimbus 3 and Nimbus 3 Professional systems 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 Nimbus 3 and Nimbus 3 Professional 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 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.
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.

3. Installation The Nimbus 3 and Nimbus 3 Professional systems are very simple to install using the following guidelines.
Refer to Section 4, Page 11 “Controls, Alarms and Indicators” for a comprehensive description of the controls and indicators on the pump and mattress.
Preparing the Nimbus 3 and Nimbus 3 Professional Systems for Use 1. Remove the system from the packaging. You should have the following items: • Nimbus 3 pump, with integral mains power cord. • Nimbus 3 mattress replacement or the Nimbus 3 Professional mattress replacement. • Bed bracket. • Tubeset. Installing the Nimbus 3 or Nimbus 3 Professional Mattress
1. Remove the conventional mattress from the bed frame and check that there are no protruding bed springs or sharp objects on the bed frame surface. Heavily ridged bed baseboards may require special considerations for correct system operation - consult your ArjoHuntleigh representative. 2. Unroll the mattress onto the bed base and make sure that the CPR is at the foot end, and the CPR label is hanging freely. 3. Attach the mattress to the bed frame using the hook and loop securing straps.
If the bed can be profiled to any position (i.e. raised or lowered), attach the mattress to the movable parts of the bed only.

Pump Indicators
The pump front panel has the following indicators:
ON / RESET ALARM
The green ON / RESET ALARM indicator below the POWER switch is illuminated when the mains power is connected and the pump switched on.
STATIC Mode
The indicator on the STATIC button is illuminated when Static mode has been selected for operation.
Alarm MUTE
The indicator on the MUTE button is illuminated when an audible alarm has been silenced.
The indicator will NOT be illuminated when a Power Fail alarm is muted. WAIT
The WAIT indicator is illuminated when the mattress is being inflated. The indicator will remain illuminated until the mattress has been fully inflated. This may take up to 15 minutes.
HIGH PRESSURE
The HIGH PRESSURE indicator is illuminated whenever the pump detects high pressure within the mattress.
Hi mmHg
LOW PRESSURE mmHg Lo
If this condition occurs, the air supply from the pump is switched off until normal pressure is detected. After 2 seconds of normal pressure being detected the indicator is switched off and the air supply restarted. The LOW PRESSURE indicator is illuminated whenever the pump detects low pressure within the mattress. This may indicate that there is insufficient pressure to support a patient or that the Transport control is turned to the TRANSPORT position whilst the pump is on and connected to the mattress. The LOW PRESSURE indicator will be switched off once normal pressure is reached.
Alarm
The pump unit incorporates a sophisticated alarm detection system that differentiates between patient movement and genuine alarm conditions. Whenever an alarm condition is detected the red Alarm triangle starts flashing together with an indicator of the cause of the alarm. Additionally, an audible warning will sound, which can be cancelled by pressing the Alarm MUTE button (Refer to “Alarm MUTE” on page 11). The triangular Alarm symbol is displayed with one or more of the following indicators:
12
• LOW PRESSURE (Refer to “LOW PRESSURE” on
page 12). • HIGH PRESSURE (Refer to “HIGH PRESSURE” on
page 12). • PUMP FAULT (Refer to “PUMP FAULT” on
page 13). • POWER (Refer to “POWER Fail” on page 13). For all alarm conditions except Power Fail, once the alarm condition has been detected and displayed, it can only be cancelled by switching the pump unit off and then back on. Refer to Section 8, Page 27 “Troubleshooting” for possible causes of the above alarm conditions. PUMP FAULT
The PUMP FAULT indicator is illuminated when an internal pump malfunction is detected. The fault can only be rectified by carrying out a service on the pump.
POWER Fail
The POWER indicator will flash when a mains power failure has been detected. The alarm will continue until the mains power is resumed or the pump is switched off using the POWER switch on the pump control panel.
Service Indicator
The symbol will be illuminated after a set number of running hours to indicate that the pump is ready for a service. This service period is set to 12 months.
The pump will continue to operate normally even when the illuminated.
