2. Clinical Applications
Indications The Alpha Active 4 system is indicated for the prevention and/or
management of all categories1of pressure ulcer, when combined
with an individualised, comprehensive pressure ulcer protocol:
for example, repositioning, nutritional support, skin care.
Selection should be based upon a holistic assessment of the
patient’s individual care needs.
The systems represent one aspect of a pressure ulcer
management protocol; all other aspects of care should be
considered by the prescribing clinician.
If existing wounds do not improve or the patient's condition
changes the overall therapy regimen should be reviewed by the
prescribing clinician.
The above are guidelines only and should not replace clinical
judgement.
The
Alpha Active 4 mattress is designed for patients weighting up
to 200 kg (440lb).
Contraindications Do not use Alpha Active 4 system for patients with unstable spinal
fractures.
Cautions If patients have other unstable fractures, or conditions which may
be complicated by a soft or moving surface, advice should be
sought from an appropriate clinician before use.
While the
Alpha Active 4 system has been designed to manage
patients up to the weight limits indicated above, those
approaching this upper limit are likely to have additional care and
mobility needs and may be better suited to a specialist bariatric
system.

Alarms and Indicators
Low Pressure
Indicator
The Low Pressure indicator is illuminated whenever the pump
detects low pressure within the mattress replacement. An audible
alarm will sound, but the audible alarm can be muted by the mute
button.
The indicator will extinguish once normal pressure is reached.
Service Indicator/Pump Fault
The Service/pump fault indicator will illuminate and remain on if
the pump has detected an internal fault. A service engineer
should be called.
Power Fail Indicator The Power Fail indicator will illuminate when a mains power
failure has been detected. An audible alarm will sound until power
is resumed or the pump is switched off using the on/off button.
NOTE
See “Troubleshooting and Alarm Conditions” on page 16 for
possible causes of Low Pressure.
NOTE
Weight settings are affected due to power fail. There are two
variants of pump in the market as follows:
1. The pump will revert to a default patient weight setting of 125
kg
(275 pounds) once power is restored after a power outage or
generator test.
2. The pump will revert to the last setting set by the caregiver
once power is restored after a power outage or generator test.
To determine which pump is being used once the pump is
operating, set the pump to 20 kg (44 pounds) and disconnect
from the power supply. Reconnect power and if the pump
reverts to 125 kg (275 pounds), you have pump 1, and if it
reverts to 20 kg (44 pounds), you have pump 2.

5. Mattress - Pump Operation
These instructions cover day-to-day operation of the system. Other operations, such as
maintenance and repair, should only be carried out by suitably qualified personnel. .
Quick Start Before using the Alpha Active 4 mattress replacement make sure
it has been installed correctly in accordance with “Installing the
Mattress” on page 6, and ensure that the CPR unit on the
mattress is clicked into the closed position.
1. Connect the pump to the mains power supply using the
supplied cable and switch on the pump.
2. Press the On/Off button on the side of the pump.
3. Select appropriate cycle time.
4. Select patient weight on pump. This should serve as an
approximate guide only. An independent clinical determination
needs to confirm that the patient is properly supported.
5. Allow approximately 30 minutes for the mattress
replacement to inflate fully.
6. Place a bed sheet loosely over the mattress without
tucking, to gain maximum pressure redistribution.
Support Setting
Procedure
It is important to follow the correct support setting procedure to
ensure the patient receives adequate support (lift) while
achieving maximum pressure redistribution and comfort.
7. Lie or sit the patient on the mattress.
8. Wait 10/20 minutes while the pump adjusts the pressures.
9. Ensure that the patient is not ‘bottoming out’. To do this,
unfasten the cover and slide a hand beneath the patients
sacral area to ensure at least 2.5cm clearance between the
sacrum and bed base.
10. If the caregiver feels less than 2.5cm of support material,
the patient has bottomed out and the support pressures
should be adjusted accordingly.
NOTE
Refer to “Controls, Alarms and Indicators” on page 8 for a comprehensive description of the
controls and indicators on the pump.
WARNING
Do not place the patient on the mattress until it is fully inflated.

11
Changes in Patient
Position
When a patient is in the lying or supine position, their body weight
is dispersed over a large area. When in the sitting position, their
body weight is concentrated within a much smaller area and
therefore will require more support than in the lying position.
Therefore, when the patient changes position, it may be
necessary, in order to maximise the benefit of the support
surface, to make adjustments to the setting of the patient weight
selector.
From Lying to Sitting - Increase weight selector setting.
From Sitting to Lying - Decrease weight selector setting.
This adjustment should be in conjunction with independent
clinical determination of appropriate support.
Static Provides a stable, non-moving support surface for instances
where active therapy is not indicated e.g. to carry out nursing
procedures or for patients unable to tolerate a moving surface. In
Static mode the support surface remains constant (all cells are
equally inflated). Additional nursing assessment must be
undertaken in order to direct an individualised repositioning
programme.
When operating the system in Static mode it may be necessary,
where possible, to reduce the pressure setting to increase patient
comfort and safety.
Power Fail Condition If a Power Fail condition arises disconnect the tubeset from the
pump and place the attached cap over the end of the tubeset to
put the mattress into transport mode. Once power is resumed, re-
connect the tubeset to the pump and carry out the “Support
Setting Procedure” on page 10 to continue therapy.
To Disconnect the
Tubeset
To disconnect the tubeset at any time, depress the buttons on the
top and bottom of the tubeset connector pull the tubeset
connector away from the pump.
To deflate the mattress Refer to “To Deflate and Store the Alpha
Active 4 Mattress” on page 12.

12
Transport Mode To transport a patient using the Alpha Active 4 mattress
replacement, disconnect the tubeset from the pump and place
the attached cap over the end of the tubeset to put the mattress
into transport mode. This will automatically switch the mattress
into transport mode.
The patient will remain supported by the mattress for up to 12
hours.
To resume normal operation, simply reconnect the tubeset and
run the pump.
To Deflate and Store the Alpha Active 4Mattress
To deflate the
mattress:
1. Disconnect the tubeset from the pump.
2. Activate the CPR control to deflate the mattress.
To store the mattress Following deflation:
1. Bring the tubeset over the mattress to lie parallel to the foot
end of the mattress.
2. Roll the mattress from the foot end toward the head end of
the mattress.
Caution
Transport mode is non-therapeutic offering support only for up to 12 hours. It
is recommended that when in transport mode the patient is frequently
monitored.

13
CPR Control
In the event of a patient suffering cardiac arrest and CPR needing
to be administered:
To activate CPR Located at the head end of the mattress replacement (on the
same side as the tubeset) is a red strap labelled CPR. In the
event of a cardiac arrest pull this from the mattress to deflate.
To reset CPR To re-inflate the mattress, simply replace the stopper securely
into the manifold.

6. Decontamination
The following processes are recommended, but should be adapted to comply with the local or
national guidelines (Decontamination of Medical Devices) which may apply within the Healthcare
Facility or the country of use. If you are uncertain, you should seek advice from your local Infection
Control Specialist.
The
Alpha Active 4 system should be routinely decontaminated between patients and at regular
intervals while in use; as is good practice for all reusable medical devices.
To clean Clean all exposed surfaces and remove any organic debris by
wiping with a cloth moistened with a simple (neutral) detergent
and water. Dry thoroughly.
Chemical Disinfection To protect the integrity of the cover we recommend a chlorine-
releasing agent, such as sodium hypochlorite, at a strength of
1,000ppm available chlorine (this may vary from 250ppm to
10,000ppm depending on local policy and contamination status).
Wipe all cleaned surfaces with the solution, rinse and dry
thoroughly.
Alcohol based disinfectants (strength 70%) may be used as an
alternative.
Ensure the product is dry before storage.
If an alternative disinfectant is selected from the wide variety
available we recommend that suitability for use is confirmed with
the chemical supplier prior to use.
Thermal Disinfection For information for the mattress top cover, including laundering
guidelines, refer to “Cover Specification” on page 20.
