3. PRODUCT DESCRIPTION
3.1 Environment
Your dynamic mattress system is intended for use in the following environment:
• A hospital where intensive/acute care is provided and medical supervision is
required and monitoring provided.
3.2 Intended Use
The Artemis dynamic mattress system is a high quality air support surface suitable for
individuals at very high risk, those with up to and including grade 4 pressure ulcers,
needing frequent monitoring and positioning. Via the automatic changing pressure in
the air cells the mattress provides comfort and pressure relief to patients vulnerable to
pressure damage by providing regular periods of pressure reduction to aid blood and
lymphatic flow to vulnerable tissue.
The mattress system is designed for use on both standard and profiling bed frames.
Ideally, patients allocated to this system will have some degree of independent mobility
or can be repositioned according to individual needs.
For assistance in setting up, using or maintaining your dynamic mattress system or to
report unexpected operation refer to the contact details found in section 2.

The zoned mattress offers 3 static head cells, 12 torso cells and 8 heel cells.
The cells can be inflated between a range of 13mmHg and 70mmHg, dependent on the
function chosen.
The heel section has narrower and lower cells. The lower cells offload pressure to
protrusions such as the heels and the narrower cells offer a more supportive surface
and ensure localised pressure relief for vulnerable areas.
9.4. Mattress Overview
Hold the button down until an audible signal sounds for a brief period. The screen
illuminates.
9.5.1. Turning On / Off
9.5. Control Unit Operation
The system will be ready for use after an initial inflation period of 20minutes. Once the
mattress is fully inflated the panel will instruct the user that the system is ready for use
and a short audible signal will sound.
If the system does not reach the required pressure it will sound a ‘low pressure’
indication after 20 minutes (see section 11).
To turn the system off hold the button down until the screen extinguishes.
Once a patient is positioned on the mattress the system will determine the patient’s
approximate weight and optimum pressure level within a period of 4 minutes. Once
weight detection is complete the mattress automatically defaults to alternation mode.
9.5.2. System Setup
The mattress utilises an ‘AB’ alternation cycle where alternate cells deflate and inflate.
As the system is detecting the patient weight the screen shows the changing pressure
differential between the A and B cells at that moment in time. In the illustration below A
= 34mmHg and B = 33mmHg

When the system is determining the patient weight the control unit is also calculating
the optimum pressure level for that weight of patient. The process occurs every
60 minutes or when the control unit detects a significant change in weight. The
detection works by increasing the pressure in all cells to maximum and then
decreasing them to the lowest possible supportive pressure where the patient
weight is at its heaviest (i.e. sacral, legs etc.).
The weight guidance indicator is accurate to ±10kg. In the illustration below the
weight is approximated to be 100kg with an alternating pressure of 13mmHg.

introduce a hazard it can be hidden, see 9.5.4.3.
Warning
Once the system has set itself for the patient, re-check it after approximately 20-
30 minutes to ensure the patient is comfortable and that the system is functioning
correctly.
The control unit will automatically lockout all functionality 2 minutes after a function
change. To unlock the control unit the ‘lock’ button is pressed for 2 seconds. To re-
engage the lock the button can either be again pressed for 2 seconds or the user can

****MATTRESS DISCONNECT**** MUTE
Please make sure the connector is
securely fastened. (note, fault shown is an example only)
Re-pressing the mute button reactivates the audible signal.
The mute setting will self-cancel after 30 minutes and the audible signal will re-sound.
Note: If the ‘power failure’ indicator activates the mute button will not silence
the audible signal. To silence, the system must be turned off by pressing the power
button.
When silencing the ‘power failure’ indicator the audible signal will not
reactivate after 30 minutes and all lights will extinguish – There will
be no indication that the system is powered down. Ensure power is
returned to the system as soon as possible to resume pressure relief.
Warning
When pressed a menu appears offering 4 different settings:
9.5.4. System Functions
9.5.4.1. Therapy Selection
1: Alternating
2: Constant Low Pressure
3: Pulsation
4: Max Inflate
Use the up/down cursor key followed by the selection key to initiate the chosen
setting.
1) Alternating: Operates an ‘AB’ cycle where alternate cells deflate and inflate over a
defined time period (see section 9.5.4.3) causing the pressure over any one part of
the body to change regularly, actively encouraging tissue perfusion.
2) Constant low pressure: Reduces the contact pressure by increasing the surface
area over which the patient is supported and by contouring to the shape of the
body, therefore redistributing pressure away from vulnerable areas. In this setting
the system runs in a static mode where the cells are not alternating and are within a
pressure range of 10 to 40mmHg (patient weight dependent).
When using the constant low pressure setting, to return to alternating it is necessary
to manually reselect alternating from the therapy menu, it will not automatically
default back.

19
3) Pulsation: Creates tissue stimulus by alternately increasing and decreasing the cell
pressure of the constant low pressure mode by 20% in each direction.
When using the pulsation setting, to return to alternating it is necessary to manually
reselect alternating from the therapy menu, it will not automatically default back.
4) Max inflate: Inflates the cells to maximum pressure (40mmHg) to provide a stable,
static support surface.
The system will automatically revert back to alternation mode after 20 minutes for
patient safety.
When pressed a menu appears offering 3 different settings:
9.5.4.2. Comfort Control
Use the up/down cursor key followed by the selection key to initiate the chosen
setting.
By selecting this function the softness / firmness of the mattress can be manually
altered, dependent on the patient’s requirements. The pump defaults to medium.
Firm = + 5mmHg
Medium = Automated pressure setting
Soft = – 5mmHg
Before changing the pressure a clinical judgement is required from frequent
monitoring and repositioning of the patient.
