Technical Description

The Nimbus 2, Nimbus 3, DFS 2, DFS 3 and Nimbus 3 Professional are Dynamic Flotation Systems
for use in aiding the prevention, treatment and management of pressure sores.
It is a powered, air-filled mattress replacement system with microprocessor-aided control and alarm
functions which have LED indication on the front panel of the pump.

Operating Principle

The patient is supported by twenty cells which are enclosed by a polyurethane coated fabric cover. This
cover has waterproof, vapour permeable, and two-way stretch properties.
The system incorporates a sensor that automatically adjusts the support pressure within the system to
accommodate different weight patients and their weight density or distribution. This sensor pad, known
®
as the Auto-Matt sensor, optimises the pressure to which the cells are inflated to be the minimum to
support that patient in a given position.
Small adjustments can be made to the mattress pressure, using the comfort control knob on the pump.
This is a patient comfort feature to make small adjustments to the softness or firmness of the mattress.
The Nimbus 3 and DFS 3 mattress also includes the HeelGuard
is designed to maximise pressure relief under the heels.
