Before operating or servicing the Position Pro™ mattress system, it is important to read and understand all
information in this manual. Carefully read and strictly follow these guidelines. The Warnings and Cautions are
repeated throughout the manual, where applicable.
To ensure safe operation, methods and procedures must be established for educating and training the staff.
U.S. Federal law restricts this device be sold by or on the order of a physician.
WARNING
The Turn Assist function should only be used or operated by a skilled medical professional.
Explosion risk. Do not use in the presence of flammable mixture with air or with oxygen or nitrous oxide.
Electrical shock risk. Refer all servicing to qualified personnel.
The mattress is equipped with a hospital grade plug for protection against shock hazard. It must be plugged
directly into a properly grounded three-prong receptacle. Grounding reliability can be achieved only when a
hospital grade receptacle is used.
Medical electrical equipment requires special precautions regarding EMC and needs to be installed and put into
service according to the EMS information provided within this manual in order to prevent equipment malfunction.
Portable and mobile RF communication equipment can affect Medical Electrical Equipment.
Do not turn patient with unstable fractures, unstable spinal cord injuries or those in skeletal traction. Death or
serious injury could result.
Risk of injury. Use of dynamic mattress systems for stroke victims should be only under physician’s order.
It is the responsibility of the caregiver to monitor the patient’s condition at regular intervals to ensure patient
safety.
Consult physician if redness or skin breakdown occurs.
Failure to position the patient along the mattress center line before starting the Turn Assist could result in injury.
Check patient frequently to ensure proper positioning and mattress inflation.
Rotation angles will differ according to patient size, patient weight, shoulder width and patient position. Monitor the
patient closely to ensure that the unit achieves the desired angle.
Ensure that all tubing and wiring connected to the patient is long enough, stabilized and secure to assure safe and
unrestricted lateral rotation/elevation of the patient. Be sure to monitor the patient frequently.
To avoid injury when using the Turn Assist function, take special care not to extubate intubated patients.
Always secure the mattress straps to the bed frame to prevent the mattress from sliding and causing patient
injury.
To help ensure patient safety, always raise the bed siderails before beginning Turn Assist.
Do not leave patient unattended during Turn Assist. Serious injury could result.
Ensure CPR straps are always accessible.
Disinfect the mattress between patients. Failure to do so could result in cross-contamination and infection.
If a big spill occurs that cannot be cleaned or dried adequately, changing the cover will be required. Also, open the
mattress to verify if there is fluid inside.
Unplug the mattress power cord from the wall outlet before cleaning the mattress. Failure to unplug the unit could
damage the equipment or result in personal injury.
Do not immerse the mattress or the foot box in cleaning or disinfectant solutions. Do not allow liquid to pool on the
mattress or the control box. Immersion or liquid pooling could cause malfunction resulting in equipment damage
or patient injury.
Allow the control box to completely dry before placing the mattress over it. Excess moisture could cause equipment
malfunction resulting in equipment damage or patient injury.
To reduce risk of patient or user injury and equipment damage, do not exceed the safe working load of the hospital
bed frame when supporting both the patient and the Position Pro™ mattress.
If changing the angle of the bed during Turn Assist, monitor the patient for at least one complete cycle to ensure
that the patient achieves the desired angle.
If the Alarm “Call Maintenance” occurs, immediately remove the patient from the bed and call your service
personnel.

Summary of Safety Precautions
Return To Table of Contents

10 2920-009-001 REV A www.stryker.com
WARNINGS (CONTINUED)
Do not perform a “Burn In” (electronic or electrical tests) with the patient on the mattress to ensure patient safety.
Do not use the pendant to move the bed.
To avoid patient injury, do not use the side straps to transport the patient.
To avoid possible injury and assure proper operation when using the Position Pro™ mattress on a bed equipped
with:
SCALES
Follow the manufacturer’s instructions for use of the scale system.
Do not zero bed scales or weigh patient with Turn Assist active. Patient motion and position resulting from the
Position Pro™ mattress may adversely affect the scale system performance.
Confirm proper scale system operation following mattress installation. For best results, secure the Position Pro™
mattress power cord to prevent damage to the cord and interference with the bed frame and the scale system.
BED EXIT SYSTEM
It is recommended to use the Position Pro™ mattress with the Bed Exit System.
Follow the manufacturer’s instructions for use of the Bed Exit System.
Be sure there is no bed or mattress movement when initializing the Bed Exit System. The patient motion and
position resulting from the Turn Assist may adversely affect bed exit system and performance.
Confirm proper Bed Exit System operation when used in conjunction with Turn Assist.
CAUTION
Do not drop the foot section of the mattress back onto the bed frame. Abruptly dropping the mattress foot section
could seriously damage the controls and cause malfunction.
The Position Pro™ mattress should not be used adjacent to or stacked with other equipment to avoid malfunction
(excluding on a bed).
The mattress cover must be completely dry before storage or adding linens. Failure to remove excess disinfectant
could cause degradation of the cover material.
Follow all applicable safety rules and protocols concerning patient and care giving safety.
To prevent pulling, removal or breakage, stabilize and secure all patient lines and tubing before starting Turn Assist
all together.
Monitor the patient’s skin condition regularly to ensure skin integrity.
Avoid contact of sharp objects with mattress. Punctures, cuts and tears in the cover could result in contamination
of the cushions, prevent proper air pressure control and compromise therapy and safety.
If fluids spill on any part of the pendant, immediately unplug the power cord from the power source. Remove the
patient from the mattress and clean up the fluid. Fluids can cause corrosion of components and may cause the
mattress to operate erratically or may make some functions completely inoperable. Do Not put the mattress back
in service until it is completely dry and has been thoroughly tested for safe operation.
The bed’s caster brakes should always be locked except during transport to prevent unintentional movements.
The bed should always be in the lowest position when the patient is unattended to minimize fall consequences.
Siderails are not intended to be a patient restraint device. It is the responsibility of attending medical personnel
to determine the appropriate manner of restraint and the siderail positioning necessary to ensure a patient will
remain safely in bed.
