The Dyna-Form Mercury Advance Trolley Mattress has been designed especially for users considered to be that of Very High
Risk of pressure ulcer development in potentially lengthy A&E waiting environments. This product can be made to measure in
order to fit most trolley designs and is ideal for use in busy A&E departments that have an extensive patient turnover. Offering high
levels of patient comfort, this system has the facility to “step up” to that of a dynamic mattress when clinically required. Similarly,
the mattress function can be downgraded as the patient’s condition improves. These features make it particularly beneficial for use
in an acute environment and help reduce moving and handling, logistical and decontamination impact costs. A higher maximum
weight capacity, up to 40 stone / 254kg, allows the product to meet the modern challenges of those heavier clients. All component
parts are interchangeable and replaceable, maximising product life and reducing environmental impact. The outer cover
comprising a high frequency welded, multi stretch and vapour permeable fabric satisfies the strictest infection control policies.

1. Introduction
The Mattress consists of a foam head cell and series of 14 transverse air cells, each containing a unique
foam profiled insert, which are in turn held within a foam U Core, all protected by a vapour permeable
waterproof cover. The single head end cell and the formers consist of foam only. The transverse cells are
arranged into alternate pairs of A and B cells which are filled and emptied in sequence.
In Static Mode, the mattress attains the pressure reducing properties of the Dyna-Form Mercury
static foam mattress (details available on request), whilst in Alternating Mode the mattress is able to
offer similar properties to a pressure relieving dynamic system.
The digitally controlled Power Unit controls a pump that allows air to flow into, or out of the air cells
as required according to the operating mode selected. It also maintains the air pressure within the
mattress at the required level and controls the action of the audible/visual Audible Warning System in
the event of mains supply failure or over or under inflation pressure. A CPR Valve located at the pump
end of the umbilical hose permits the rapid deflation of the Mattress in an emergency.
Power Switch Audible Warning Reset
The power switch simply switches the mains power to the pump on and off.
When the pump detects an Audible Warning condition, this can be silenced (see page 5)
and re-set by switching the pump off and then back on again.
CPR Valve
Please ensure that the CPR connector is always placed fully home, prior to inflating the mattress.
NB: The mattress will NOT inflate properly should this not be the case.
The CPR connector is only to be used in the event of a clinical emergency for priority use.
However, disconnecting this function will cleverly deflate air rapidly from the mattress in
readiness for transport / static mode.

This symbol when illuminated (The green indicator light) is not used to indicate that the
equipment is on or ready for use.
When a patient requires a true dynamic function or indeed more pressure in the cells, as they
may be uncomfortable or feel as though the support surface is too soft or unstable, then please
select a “High” setting (pressure 26mmHg). This must only be used by a trained clinician as often
too high pressures can further agitate certain patient conditions.
When a patient requires less pressure in the cells, as they may be uncomfortable or indeed hyper
sensitive to cell movement or indeed if the patient is still reddening further, then please select a
“Low” setting (pressure 18mmHg). This must only be used by a trained clinician.
This function is used to silence the Audible Warning. The LED will remain lit if the Audible
Warning has been silenced previously, however a fault is still detected. Refer to the power switch
in order to re-set fully. If the Audible Warning continues to sound repeatedly, along with an
illuminated light, then an engineer must be called.
This symbol indicates an “Audible Warning Failure”.
Please see troubleshooting guide below for how to re-set.
This symbol when illuminated indicates a Service is required.
DHG recommends a service every 8760 hours of operation (one continuous year running).
LED Mode Settings
Note: Please ensure (when available) that all securing straps on the base of the mattress are secured onto
the MOVING PARTS of the bed frame.
