2. Product Overview Alternating Mattress system (see cover) Dyna-Form Air Pro-Plus is an Alternating Mattress Replacement System providing pressure application and release to patients with, or vulnerable to, pressure ulcers. It is designed to replace an existing mattress and can be used on both standard and profiling bed frames. Mattress This system includes a static head cell(s) to provide static “pillow” support for optimum user comfort, while air pressure in the other cells is alternated over a 10 minute cycle. This provides regular periods of pressure reduction to aid blood and lymphatic flow to vulnerable tissue. Control unit The Control unit provides the air supply to the Mattress. • It is controlled via a touch panel with integrated digital display. The Audible Warning sounds when pressure fails or power is interrupted. Audible Warning Mute silences the Audible Warning for maximum of 20 minutes – the Audible Warning resumes if cause of failure is not resolved. The Audible Warning will sound for up to two hours following an interruption to power. • The Control Unit includes a back up power battery for the Audible Warning. This battery is continuously re-charged and will last the lifetime of the product. • Buttons on the control panel adjust the three comfort level settings. • The Warning LED indicator and Audible Warning Mute completes the profile. The visible and audible warning functions have a number of indicators depending on the cause of the failure. The mains supply to the Control Unit can be easily disconnected and is designed to detach if tugged too firmly - protecting the internal wiring of the unit. Should this occur, the alternation sequence is suspended and the Mattress cells remain inflated and/or deflated based on the current cycle. The Power Down Audible Warning will sound.

USER MANUAL

Operation Mattress Function Establishing Pressure (supine patient) With the patient lying supine (on their back, face upwards), select the soft, medium or firm setting based on patient weight and comfort requirements. You may also select the ‘Dynamic’ or ‘Static’ setting using the relevant buttons. Before changing or lowering the pressure, ensure the system is working effectively by performing a ‘bottoming out’ test: Bottoming Out Test When altering the pressure setting, ensure the patient is not ‘bottoming out’ (insufficiently supported by the air cells and therefore coming in contact with bed base). 1. Ensure system is in alternation mode but is not undergoing an alternation. 2. With the patient lying in a supine position, unzip top cover just past sacral (bottom) region. 3. Slide your hand along a deflated cell under the patients sacral area (bottom). The inner static cell will remain inflated but your hand should slide easily between patient and base. 4. If a hand can pass under patient then the patient is adequately suspended and pressure can be lowered. 5. Repeat Bottoming Out test after pressure has been lowered. In the event of a system malfunction, the Audible Warning will activate and pressure LEDs will flash. Establishing Pressure (inclined patient) When moving the patient to a sitting or more upright position, pressure may need to be increased to a medium or firm setting in order to provide added support and to avoid ‘bottoming out’. It is important to return to the original pressure setting when the patient returns to the supine position. Wait a minimum of 12 minutes between pressure adjustment and patient assessment, as it may take a cycle for the system to adjust. CPR Function Rapid deflation of the Mattress may be required for emergency treatment or to decommission the system. Firmly pull the Rapid Release /CPR Tag from the side of the Mattress to rapidly deflate the entire system. To re-inflate the system after the Rapid Release/CPR Tag has been removed replace as such, ensuring all sealing connectors are firmly attached and restart the Control Unit. Wait for the Mattress system to gain optimal pressure. Perform a Bottoming Out test after inflating the mattress following rapid deflation. Mattress replacement system The Air Pro-Plus is a replacement mattress system. Remove the standard / foam hospital mattress before patient use.

Operation Transport Function

1. Before patient transport, switch modes from alternating to static and wait for 10 -15 minutes for cells to inflate to maximum pressure. 2. Turn off the Control Unit. 3. Remove the mattress connection from the Control Unit. Allow air to escape for a few seconds before sealing with the attached transport cap, see picture on cover. This will soften the Mattress surface for pressure relief and comfort. Air can be sealed in the system for 30 hours as a transport feature. If the patient is responsive, check comfort level based on current pressure and adjust accordingly. Always perform a ‘bottoming out’ test (see page 8) to ensure the patient is adequately supported and not touching bed base. System Removal 1. Turn off the Control Unit by pressing the Power button for at least two seconds and unplug the power cable. 2. Remove the Rapid Release Handle from the Control Unit. 3. Place Control Unit and power cable on top of the Mattress and detach Mattress from the bed frame. 4. Once air has been released from all cells, roll up the Mattress and return all items to Carry Bag for safe keeping. Prior to re-starting the system, ensure the Rapid Release Handle is firmly connected to the Control Unit.
