2. Clinical Applications Indications

The Alpha Active 4 system is indicated for the prevention and/or management of all categories1 of 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. NOTE The above are guidelines only and should not replace clinical judgement or experience.

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. NOTE See “Troubleshooting and Alarm Conditions” on page 16 for possible causes of Low Pressure.

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 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. . 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.

Quick Start

Support Setting Procedure

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.

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.

10

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, reconnect 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.

11

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.

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.

To Deflate and Store the Alpha Active 4 Mattress To deflate the mattress: To store the mattress

1.

Disconnect the tubeset from the pump.

2.

Activate the CPR control to deflate 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.

12

CPR Control IMPORTANT IN THE EVENT OF CARDIAC ARREST 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.

13

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.

WARNING Remove the electrical supply to the pump by disconnecting the mains power cord from the mains power supply before cleaning. Protective clothing should always be worn when carrying out decontamination procedures.

Caution Do not use Phenol-based solutions or abrasive compounds or pads during the decontamination process as these will damage the surface coating. Do not wring/mangle, boil or autoclave the cover. Avoid immersing electrical parts in water during the cleaning process. Do not spray cleaning solutions directly onto the pump.

To clean

Chemical Disinfection

Clean all exposed surfaces and remove any organic debris by wiping with a cloth moistened with a simple (neutral) detergent and water. Dry thoroughly. To protect the integrity of the cover we recommend a chlorinereleasing 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.
