Comfort Control
Pump Indicators The pump front panel has the following indicators:
Run Mode
Static Mode
Alarm Mute
Wait
High Pressure
Low Pressure
Alarm
The Nimbus 4 and Nimbus Professional systems
automatically compensate for patient weight
distribution and position, to optimise the mattress
pressure relieving performance. However, 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 green Run indicator below the Run/Standby button
is illuminated to confirm the pump is in Run mode.
The yellow indicator on the Static button is illuminated
when Static mode has been selected for operation.
The yellow indicator on the Mute button is illuminated
when an audible alarm has been silenced.
The Alarm Mute button does not operate in a Power
Fail condition.
The Wait indicator is illuminated when the mattress is
being inflated.
The indicator will remain illuminated until the
mattress has been fully inflated.
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 two
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.
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 yellow
Alarm triangle illuminates together with an indicator of
the cause of the alarm. Additionally, an audible warning
will sound, which can be temporarily silenced by
