INTRODUCTION
This manual should be used for the initial set up of the Restep® system and for reference purposes.
Clinical Indications for use
The primary application of the Restep®system is for the prevention of Deep Vein Thrombosis (DVT)
due to the presence of risk factors for thrombus formation during orthopedic, trauma, neurology,
urologic, critical care, general medicine, obstetrics, and general surgery.
This system should be used when prescribed by a physician.
Garments should be removed regularly to inspect the skin.
Patients with diabetes or vascular disease require frequent skin assessment.
When appropriate, patients should be instructed in the proper use of the system and any
problems should be reported to the nursing staff.
The garments should be applied to the patient prior to the induction of anesthesia.
If the garment cannot be applied to the operative limb during surgery, it may be applied to
the limb once the patient reaches the recovery room. For a non-surgical patient, the system
should be applied as soon as the risk of DVT is identified.
The system should be used continuously until the person is fully ambulatory. The therapy can
continue with leg garments for people with limited mobility.
Contraindications
The Restep®system should NOT be used in the following conditions:
Severe arteriosclerosis or active infection.
Suspected or known acute DVT.
Severe congestive heart failure or any condition where increased fluid to the heart
may be detrimental.
Existing pulmonary edema.
Local skin or tissue conditions in which the garments would interfere.
If in doubt, refer to the patient’s physician before using device.
CAUTION: US Federal law restricts this device to sale by or on the order of a physician.
Precautions
Do not drop the power adapter or pump as it may result in damage to the components

PUMP OPERATION
Switching the pump on and off
Light Indicators while pump is off
No light = pump off and not connected to power
BATTERY CHARGE light (flashing green) = battery charging
BATTERY CHARGE light (solid green) = battery charged
To start pump operation, press the POWER button once and wait. The pump will undergo a software
auto-check for a few seconds. During this time, the LEG GARMENT light may flash. After the auto-check
is completed, the LEG GARMENT light will be lit constantly.
NOTE: When the POWER button is pressed, Restep pumps using Software PSoC Version 2.3 will also produce
an audible beep and the BATTERY CHARGE and LOW BATTERY lights will flash simultaneously. A label indicating
Software PSoC Version 2.3 can be found on the back of the pump if applicable. Please be patient and do not
press the POWER button again or you may turn the pump off.
The pump will now begin its normal operation cycle. Allow the pump to run for several cycles to allow
the garments to inflate and fit their shape to the patient’s extremity. During this time the
“LOW PRESSURE” alarm may activate. If, after a few cycles, this alarm does not reset, please refer
to the trouble-shooting guide.
To end pump operation, press POWER button again. When the pump is powered down during an
inflation cycle, the Garment TYPE light will flash while the valves open and drain the pressure from the
garment. This ensures the system is left in a safe deflated mode for the patient.
NOTE: You may change the TYPE or MODE settings only within the first 60 seconds of the initial Power button
press; after 60 seconds, TYPE and MODE selection keys are inactivated. It is NOT recommended to change
garments after initial setup while pump is in use. The pump should be turned off during a garment change to
avoid unnecessary alarm disturbance to the patient.
Garment TYPE selection
The user may select between the LEG GARMENTS type or FOOT GARMENTS type by pressing the Type
Selection Key. Press this key until the desired type is illuminated by the garment type indicator LED.
LEG: This is the default setting for calf, bariatric calf, and/or thigh garments. The operating inflated
pressure is 40mmHg and the compression delivered is considered a uniform-type compression. The
LEG GARMENT light will flash during initial setup of the pump and then will be lit constantly during use.
FOOT: Select this button for foot garment use. The operating inflated pressure is 80mmHg and the
compression delivered is considered a uniform-type compression. The FOOT GARMENT light will be lit
constantly when selected.
Note: Ensure the garments on the patient and the garment TYPE selection are the same. Do not mix leg and
foot garments on the same patient. If desired, a calf and thigh garment may be used simultaneously.

14
Garment MODE selection
The two modes available are DUAL GARMENT mode and SINGLE GARMENT mode. All garments can be
used in either mode. Press this key until the desired mode is illuminated by the mode indicator LED.
DUAL GARMENTS: This is the default setting for the pump. Each garment inflates for 12 seconds
and then deflates for 48 seconds per cycle. Inflation alternates between the two garments during
each cycle. One garment will inflate and then deflate and 30 seconds later the second garment will
inflate and then deflate.
SINGLE GARMENT: Press the MODE key once to select the SINGLE GARMENT mode. Only one
garment is used on the patient (either extremity). This garment inflates for 12 seconds and then
deflates for 48 seconds per cycle.
Note: It does not matter which extremity the garment is placed on or which connector is used.
The pump will detect this during its first inflation cycles and compensate accordingly.
Mute
When an alarm occurs, the pump will give the appropriate audible tone to inform the user of the alarm
and light the appropriate ALARM light. The user may silence the audible tone by pressing the MUTE key.

PREVENTIVE MAINTENANCE
General
The Restep®system should be inspected and tested by a qualified biomedical service technician
annually as part of Preventive Maintenance to ensure proper operation of the pump and garment
system. Inspection and testing will verify that the buttons, speaker, lights, compressors,
transducers, and solenoids function properly.
Visually inspect power adapter for abrasions, bent pins, damaged cables, and excessive wear.
Make sure the garment tubes are correctly connected and ensure they are not kinked, broken, or damaged.
Visually inspect battery for signs of damage.
Replace battery annually to ensure optimal performance of the pump.
NOTE 1: Battery (Item Number RSP152) is available from Stryker Sustainability Solutions.
NOTE 2: DO NOT disassemble the pump housing as this will void the warranty. If the pump is not operating prop-
erly, contact your Stryker Sustainability Solutions representative.
NOTE 3: Restep Pump inspection and testing may take approximately 15 minutes to execute.
