INTRODUCTION
Product Description
The Lothian II™has been designed to ensure ease of use, whilst high clinical delivery is achieved
in a single mattress. Specifically designed for use in long term care environments or equally at
home in a residential setting, this product provides high to very high risk solution (reference: clinical
case study M. Hughes 2017), when used as part of a complete care package. The cyclical cells
operate and deflate in a ten-minute alternating pattern, with a 1.5 minute equaling of cells in
between the complete cycle, therefore providing direct pressure relief and patient stability
throughout the whole dynamic process. The multi-stretch, vapor permeable cover, comprises of a
high-level coating of polyurethane, which makes it easy to clean, whilst complying with strict
infection control procedures. The rapid cell deflation system in unique in the sense that pressure
relief happens much quicker than on a standard dynamic mattress system. This prompt deflation
physically ventilates, thus allowing immediate relief between cycles, rather than awaiting deflation
under patient weight as is often the case.
Application
This product is to be used for those patients who have existing tissue damage or pressure ulcers.
It can also be used as a high-risk preventative item.
Contra indications
Patients with severe spinal injuries / fractures should not be using this product.
Do not attach the mattress to the fixed part of the bed frame. It should be secured to the moving /
working parts to ensure the bed can be profiled as required.
Patients requiring a deep cell mattress should not be considered for this particular product without
a prior clinical assessment.
This product forms part of a holistic care package and should only be used by trained personnel.
For training or further advice contact Herida Healthcare on Freephone [phone].
Working Principle
The dynamic mattress system consists of a dynamic air pump and an alternating air mattress. The
air mattress has three distinct airway chambers:
1. Pillow Chambers –Air tubes 1,2 & 3. These remain static throughout as to avoid head
movement, sickness to the user.
2. Group A Chambers –Air tubes 4,6,8,10,12,14,16 & 18.
3. Group B Chambers –Air tubes 5,7,9,11,13,15 & 17.

Lothian II™User/Service Manual
OPERATION
A and B chambers alternate inflating and deflating by using the pump connected. This air
alternating, mattress system enhances the blood circulation to treat and prevent pressure
ulcers, when part of a holistic care package. Initialisation can take up to 50 minutes to achieve
& it is recommended that a Rapid Inflator is used, where possible, to reduce the inflation time.
Static Mode
When the pump is adjusted to the static mode, air chambers A & B are both fully inflated until
52mmHg / 180 Kg is achieved. This mode is used for seating or patient transfer.
Alternating Mode
When started, both chambers A & B are initially inflated to 52mmHg / 180 Kg. Group A chambers
deflate for 5 minutes followed by both A & B inflating for 1.5 minutes. This is followed by Group B
chambers deflating for 5 minutes. This is one complete cycle.
Profiled Bed & Mattress - Clinical & Carer Considerations
If the bed is in the profiled position & the patient is touching the foam base, ensure that the pump
pressure is increased accordingly to appropriately accommodate (*see below). Unless the clinical
condition dictates, it is not advised to adjust the bed profile beyond 45°. The Lothian II™will
continue to operate beyond this but may cause increased pressure points on the patient. A fist or
hand test to ensure patient clearance under the sacral area is a best practice guide (see image
1DA and diagram of profiled mattress 2DA or visit our website (www.heridahealthcare.co.uk) under
“Education” tab section and select Dynamic Best Practice from the drop-down menu). If you are
dealing with heavier or more complex patients that require a deeper cell mattress, then please
contact your provider or seek assistance via Herida Healthcare Customer Services. The clinician
must select the correct mattress type at prescription point / patients individual circumstances.

(NB: use hand to check ensure appropriate clearance when profiled as below. Add more pressure
on the pump if required in order to achieve this. NB: Weight setting is a guide only and cell
pressure must also be taken into consideration for individual patients). Clinical judgement must
always overrule user guidance.
Image 2DA
Installation
1. Remove all packaging & place the pump either at the end of the bed on its hooks or on a
flat surface.
2. Ensure that there are no sharp or hard objects on the bed before unfolding the mattress &
laying out flat. The air inlet should be located at the feet side of the bed.
3. Use the Rapid Inflator (if available) to inflate the mattress before connecting the air tubes to
the pump. The tubes should be connected securely in place without any signs of leakage. If
a Rapid Inflator is not available, the mattress will take approximately 50 minutes to inflate.
4. Connect the pump to the socket & switch on.
5. Adjust the mode & pressure by the users condition & weight to suit.
6. In order for the alarm to activate, the system must be switched on & powered up for at least
5 minutes. This should give the internal battery on the PCB sufficient time to charge.

OPERATION
Safety Instructions
1. Ensure that there are no sharp objects, fire or abrasive materials in the vicinity. If the
mattress is damaged. Remove the patient & transfer to an alternative mode of pressure
relief. A foam underlay is provided as standard at the base of the mattress to ensure
pressure relief is maintained (to an extent) in the event of a power failure. NB This is not to
be considered as a long-term pressure relief option.
2. If there is an issue with the pump, remove the patient & transfer to another mode of
pressure relief.
Pump Operation
Power: Power On / Off
Soft / Firm: Pressure adjustment. Each single push adjusts ±5KG. Longer push adjusts ±5KG
rapidly.
Static: All tubes will inflate up to 52mmHg / 180 Kg. No alternating takes place & the digital display
will show “- - -“. The pump will revert back to the previous alternating cycle after 30 minutes.
Pressure Monitor: The light is illuminated when pressure is normal & extinguished when pressure
is abnormal. The light will continuously flash during the alternating cycle change-over.
Mute: When pushed, the audible alarm is silenced.
Lock/Unlock/Malfunction:
•Push the key for 2-3 seconds to lock / unlock the panel.
•The light will continuously flash on the following occasions: when the mattress has not yet
reached pressure during alternating cycles; the mattress has an air leak or the pressure has
dropped lower than 6mmHg.
•When the panel is unlocked, it will automatically lock itself after a period of time.
•The lock / unlock facility will be unavailable if the system cannot reach pressure.
Alarm Activation: In order for the alarm to activate, the system must be switched on & powered
up for at least 5 minutes. This should give the internal battery on the PCB sufficient time to charge.

MAINTENANCE
At point of service the following aspects must be maintained to ensure that manufacturer’s
warranty remains intact. These can be done in a non-alphabetic way, if all areas are covered:
•Ensure the pump unit and mattress / cells are fully decontaminated prior to service and are
cleaned in accordance with the schedule provided.
•Electrical safety checks / Pat Test –To be conducted annually or time of service. Please
make sure the kettle lead and plug fuse is compliant at 3amp only.
•Filters must be changed at point of return / before patient handover / new client and at time
of service.
•Rear pump fuse must be inspected and replaced if faulty –0.5A only.
•Pump casing must be opened and vacuumed internally, if any dust or particles are evident.
Never use any water / fluid internally to clean.
•Pump must achieve pressure within 20% tolerances as per page 9 of this manual –via
calibrated sphygomometer and cell attachments. Kits available to purchase via
manufacturer. Ensure that a rapid inflator is used at time of service to ensure that service
and installation time is reduced to minutes.
•Pump low pressure function is evident at 6mmHG or lower for 15-20 minutes or more.
•Cells are to be fully inflated and tested for leakage. This should be done via a pressurised
system, soak test over at least 3 cycles or under weights to replicate patient in situ.
•The tubing and connectors that run down the side of the mattress, must be clear of kinks /
debris or must not be snapped in any way. These should be running freely with air
distribution to each cell and have no leakage or deterioration of surface. A spring is situated
at the head section of the mattress tubing at to avoid kink in the critical area.
•The none return valve holding the 3 head cells must be functioning correctly. This is evident
via 3 solid static head cells / none alternating during cycle.
•A functional “soak test”, ensuring that the tactile panel / pump and mattress operates fully in
synergy. This is done by attaching and inflating the mattress to full pressure and then
increasing / decreasing both weight and other panel / button functions.
•The key lock button is effective by release / addition, holding 3 seconds or more to activate.
•CPR is to be checked functionally and deflated after all soak tests are completed.
•Mattress Cover and cells are to be inspected for puncture, tear, rip or excessive odour post
cleaning and replaced accordingly if defective.
•Calibration setting as required. See page 12 for further details.
Storage
Good ventilation will be required when storing the product & it should always be kept dry & away
from direct sunlight. Temperature should be maintained in the region of 22°C ± 3°C when in use.
Avoid repeat exposure to extreme temperatures.

Transportation
•Care should be taken when loading, unloading and during transportation & refrain
from placing heavy objects on top of the mattresses.
•Do not expos to direct sunshine for any period of time when loading and unloading &
ensure a cover is used to protect the mattress when raining or snowing.
•Do not open with a knife or sharp objects as this may damage the mattress cover.
•Always use the provided re-usable pump protector for all transportation methods. This plastic
sleeve will need to be cleaned prior to re-use for infection control purposes.
Calibration
•During service intervals or between patients, it is recommended to check pressure
tolerances (see the table on page 9) using a Herida Testing System. Calibration training
must be conducted & applied by a Herida trained technician.
Other Considerations
•Original internal fuse is F0.5A 250V. When replacing the fuse, ensure a similar type is
used and that the fuse is disposed of in the appropriate manner.
•During normal working, when the emergency deflation is needed, switch off the pump
and pull out the CPR toggle quickly.
•The mattress should be away from sharp objects to avoid any scratches or punctures.
•Put bed cover sheet or blanket over the mattress before use. No plastic or rubber
sheets should be used.
•Ensure that all the tubes remain flat & any twists / kinks are avoided.
•If any air leakage is found, check all the tube connectors and air tubes carefully to see if
any are loose or damaged.
•If any major problems or issues are found or the product is not working, stop
using immediately and ask the engineer / manufacturer / provider for assistance.
•Any discarded mattress or covers should be treated in accordance with local rules
and guidance in accordance with contaminated products.
