Arjo Nimbus 4 User manual

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.
During an alarm condition the triangularAlarm symbol will illuminate, an audible alarm will sound and one of the following indicators
will be illuminated: Low Pressure, High Pressure, Pump Fault or Power Fail.
The Low Pressure indicator is illuminated whenever the pump detects low pressure within the mattress.An audible alarm will sound
unless cancelled by the Mute button. The indicator will extinguish once normal pressure is reached. Make sure the CPR is closed,
the tubeset is connected properly and the mattress is set to Normal.
The High Pressure indicator is illuminated whenever the pump detects high pressure within the mattress.An audible alarm will sound
unless cancelled by the Mute button. If this condition occurs, the air supply from the pump is switched off until normal pressure
is detected. After two seconds of normal pressure being detected the indicator is switched off and the air supply restarted. Make
sure the tubeset is not kinked.
The Pump Fault indicator is illuminated when an internal pump malfunction is detected. Call the Service Engineer.
The Power (Fail) alarm indicator will illuminate when a mains power failure has been detected. An audible alarm will sound. The
alarm will continue until the mains power is resumed or the Run/Standby button is pressed to put the pump into Standby. If the
power failure is prolonged, switch to Transport mode and disconnect the tubing.
Examples of conditions causing the Power (Fail) alarm are mains lead removal and power failure.
The Service indicator will illuminate and remain on after a set number of running hours indicating the pump is ready for a service.
The pump will continue to function normally while the Service indicator is illuminated.
During an alarm condition the audible alarm can be muted by pressing and holding the Mute button for 3 seconds. The indicator
on the Mute button will illuminate to show the audible alarm has been silenced.
The Alarm Mute button does not operate in a Power Fail condition.
Press and hold the Static button for 3 seconds to select Static mode. An audible tone will sound when the button is pressed. The
indicator on the Static button will only illuminate when the pump is in Static mode. Press and hold the button for 3 seconds to
return to Dynamic mode.
The mattress cell pressure can be manually adjusted for patient comfort using the rotary Comfort Control. Turn the Comfort
Control clockwise for a firmer setting and counterclockwise for a softer setting.

the bed frame.
To Complete Mattress Installation
Quick Start
When the Nimbus pump is switched on using the power switch, the
pump will run a self diagnostic check for approximately 3 seconds
during which all indicators will be illuminated.
The Wait and Low Pressure indicators will remain illuminated while
the mattress inflates.Allow approximately 15 minutes for the mattress
to inflate fully.
Transport Mode
To transport a patient using the Nimbus Professional mattress,
turn the Transport control at the foot end of the mattress clockwise
to Transport. Switch off the pump and disconnect the tubeset. In
this mode the mattress will support the patient for up to 12 hours.
To resume operation, reconnect the pump, turn the transport control
counterclockwise to Normal and switch on.
CPR CONTROL
IN THE EVENT OF CARDIAC ARREST
In the event of a patient suffering cardiac arrest and CPR
needing to be administered:
To Activate the CPR:
1. Lift the red handle on the control panel at foot end of the
mattress.
SAFETY SIDES
Regarding the use of safety sides, always refer to your local trust
policy AND the product instructions for use.
If the bed has divided sections for independent elevation
of a patient’s head and/or knees, attach the mattress
to the movable parts of the bed frame only.
Zip the protective cover over the mattress. Make sure that theArjo logo
is uppermost and at the foot end of the mattress.
Check that the transport control is set to Normal and the CPR control
is closed and locked in position.
Make sure that the mains power cable and tubeset 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.
The CPR control must be visible and accessible at all times.
If the pump is to be hung from the end
of the bed, attach the bed bracket to
the bed frame.
Alternatively the pump can be placed
underneath the bed, either upright or
lying on its back.
Make sure the tubeset is securely connected to the pump and the
mattress.
Insert the mains power connector into the socket on the side of the
pump. Connect the mains power cable to a suitable mains power outlet.
2. Turn the handle counterclockwise.
3. Pull the handle away from the panel.
To Reset the CPR:
1. Turn the grey triangular seal clockwise and push onto the
connectors.
2. Turn the red handle clockwise.
3. Fold the handle flat to lock in position.
Vent Valve Control
To deflate a cell, turn the Vent Valve 180°
clockwise, to point downwards.
Refer to “Guidelines for Selecting Mattress
Vent Valves to Open” in the “Operation”
section of the product instructions for use.
