toreleasethesiderails)incaseofreorotheremergency.Monitorpatientsfrequentlyto
guard against patient entrapment.
WARNING: To help prevent inadvertent bed exits or falls, ensure the distance between the
top of side rails (if used) and top of mattress (without compression) is approximately 4.5
inches / 11.4 cm. Consider individual patient size, position (relative to the top of the side
rail), and patient condition in assessing fall risk.
WARNING: I.V. and Drainage Tubes – I.V. and drainage tubes should always have slack for
Alternating Pressure and other patient movements.
WARNING: Skin Care – Monitor skin conditions regularly and consider adjunct or
alternative therapies for high acuity patients. Give extra attention to skin over any raised
side bolster and to any other possible pressure points and locations where moisture or
incontinence may occur or collect. Early intervention may be essential to preventing skin
breakdown.

3 FEATURES
PUMP AND MATTRESS SYSTEM
Description
The Lumex LS300 Alternating Pressure / Low Air Loss Mattress System is a specialized mattress
replacement unit that utilizes low air loss technology with specialized mattress design that
provides pressure management for the treatment of pressure ulcers. The 2:1 alternating function
also provides active prevention for pressure relief, especially for those in acute care and long
term care settings (the cells inate and deate in a 2:1 cycle, meaning 1/2of the body is always
supported at any one time). The Lumex LS300 Alternating Pressure / Low Air Loss Mattress System
offers “cell on cell therapy”, whereby the cell is split in two where the bottom cells do not deate
if the upper cells are completely deated in order to provide extra protection and “zero” pressure
comfort for the patient in the event of a power failure and the mattress deates. The soft-rm
adjustment allows the patient to adjust the rmness or softness of the surface for optimal comfort
with a comfort level dial.
PUMP FEATURES
• Alternation time is set to 10, 15, or 20 minute cycle (see ALTERNATE function on page 12); or
instead, the caregiver can select the STATIC function (see STATIC function on page 12).
• Low Pressure failures will produce an audio alarm for added safety. The alarm can be
temporarily muted by pushing the front panel ALARM RESET Button, resetting the alarm for 20
min.
• The foot board mounting hanger provides convenient placement on the bed.
Pump front panel Pump rear view
MATTRESS FEATURES
• Individual air cushion design for maximum pressure distribution.
• Vented air cushion provides true low air loss therapy.
• Cell on cell design for “zero” pressure comfort during loss of power.

Use a power regulator
Kinks in the air tubes Adjust the air tubes to enable smooth
air ow
Leakage from the air cells Replace air cell if faulty
Leakage from air tube between
mattress and pump
Replace with new air tubes
Improper air tube connection Re-connect the air tubes
The pump is not functioning Power cord or power voltage Use a power regulator

11 EMC RELATED NOTIFICATION
WARNING: Medical electrical equipment needs special precautions regarding EMC and
needs to be installed according to the EMC information provided. Careful consideration
of this information is essential when stacking or collocating equipment and when routing
cables and accessories.
WARNING: RF mobile communications equipment can affect medical electrical equipment.

Recommended separation distance between
portable and mobile RF communications equipment and the LS300
The LS300 is intended for use in an electromagnetic environment (for home and professional
healthcare) in which radiated RF disturbances are controlled. The customer or the user of the
LS300 can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the LS300 as
recommended below, according to the maximum output power of the communications
equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance din
meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where p is the
maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.

The LS300 is intended for use in the electromagnetic environment (for home and professional
healthcare) specified below.
The customer or the user of the LS300 should assure that it is used in such an environment.
Emission test Compliance Electromagnetic environment-guidance

RF emissions CISPR 11 Group 1 The LS300 uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not
likely to cause any interference in nearby electronic
equipment.
