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.

Nimbus 3 Pump

The same pump is used on the Nimbus 3 and Nimbus 3 Professional systems. The pump comprises a moulded case with non-slip feet on the base and rear, and an integral carry handle. Carry Handle

Mains Power Switch

Alarm Indicators

Tubeset

Mains Power Cord

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.

Nimbus 3 Mattress

The Nimbus 3 mattress comprises the following components:

Detachable Cover 3 Head Cells 4 Thigh Cells Head End

5 “Heelguard” Cells

Drag Handle

8 Torso Cells

Securing Strap

Foot End

Carry Handle

CPR Control Pump Tubeset

Transport Control

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 Options and Features” on page 32).

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 patients weighing up to 250 kg (39 stones) and are suitable for the prevention and management of all grades of pressure ulcers.

Contra-Indications

The Nimbus 3 and Nimbus 3 Professional systems, both in alternating and static modes, should not be used for patients with unstable spinal fractures. In the case of patients with other unstable fractures, where a moving surface can be harmful, advice should be obtained from the appropriate physician before using the Nimbus 3 or Nimbus 3 Professional systems in both alternating and static modes.

Patient In Chair

If the patient will be sitting in a chair for any period of time, it is strongly recommended that a pressure reducing or relieving seat cushion is used.



The Nimbus 3 and Nimbus 3 Professional systems are an aid to the prevention and management of pressure ulcers. If there is no improvement in the patient's condition, clinical advice should be sought.



The above are guidelines only and should not replace clinical judgement or experience.

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 Huntleigh Healthcare 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. 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.

LOW PRESSURE

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 26 “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 “telephone” 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.

Transport Control

This sets the mattress into TRANSPORT mode where the support surface is equally pressurised and the pump and tubeset can be removed. In this mode the mattress will support the patient for up to 12 hours.

CPR Control

The CPR (Cardio-Pulmonary Resuscitation) Control provides a means of rapidly deflating the mattress to allow normal resuscitation procedures to be carried out.

The CPR control is used to deflate the mattress for packing and storage.

Additional Controls on the Nimbus 3 Professional Mattress The following two controls are on the opposite side of the mattress to the CPR/Transport 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 (next to the Head Section) is inflated to a constant pressure to support the patient’s shoulders. The remaining 16 cells alternate. TriCell Head Section Deflate

5. Operation These instructions cover day-to-day operation of the system. Other operations, such as maintenance and repair, should only be carried out by suitably qualified personnel.



Refer to Section 4, Page 11 “Controls, Alarms and Indicators” for a comprehensive description of the controls and indicators on the pump and mattress.

Installing the System

Before using the Nimbus 3 or Nimbus 3 Professional system make sure: 1. The system has been installed correctly in accordance with Section 3, Page 7 “Installation”. 2. The CPR unit on the mattress is closed and locked in position. 3. The Transport control on the mattress is set to NORMAL.

4. If a Nimbus 3 Professional system is being installed, make sure that on the mattress: • All 16 Vent Valves are closed. • The Head Section Deflate Control is set to Dynamic (Normal) Mode.

Inflating the Mattress



1. Switch the pump POWER switch to ON. The ON / RESET ALARM indicator below the POWER switch should illuminate. 2. The pump will now run a self test for approximately 3 seconds when all the indicators on the front panel will be illuminated. 3. If the pump detects low pressure (e.g. a deflated mattress) it will enter an inflation sequence with the LOW PRESSURE and WAIT indicators illuminated. 4. Once normal operating pressure has been reached both the LOW PRESSURE and WAIT lights will extinguish. It may take up to 15 minutes to inflate the mattress.

The three Head Section cells and the five Heelguard cells will inflate more slowly than the rest of the mattress. Testing the Power Fail Alarm

The Power Fail Alarm is powered by a rechargeable battery. The duration of the alarm will depend on the level of charge in the battery. 15
