Design Philosophy
Pneumatic compression is a clinically proven modality for minimizing the risks
associated with deep vein thrombosis.¹ The Aircast VenaFlow Elite System leverages
the same clinically proven technology as the existing VenaFlow oering, but is
presented in a low prole, light-weight design. VenaFlow Elite combines two proven
technologies, rapid ination and graduated sequential compression, to accelerate
venous velocity and enhance brinolysis. This unique combination makes VenaFlow
the only technology platform on the market that mimics ambulation.² Additionally,
VenaFlow Elite incorporates asymmetric compression for the superior emptying
of veins.³ The breathable and comfortable VenaFlow Elite calf, foot and thigh cus
enhance the patient experience, assist in increasing compliance and are compatible
with one universal pump.
Function
Standard Operation (rapid ination): The VenaFlow Elite system defaults to a
rapid ination mode. Once powered on, the system begins the compression cycle
and inates the cus one leg at a time, alternating between the two legs every 30
seconds. First the distal aircell inates rapidly within less than 0.5 seconds, then the
proximal aircell follows. The distal pressure peaks at approximately 73 mmhg ±15%
and the proximal pressure peaks at approximately 63 mmhg ±15%. These pressures
then settle at 45mmhg ±10% and after 6 seconds, the cu deates. In 54 seconds, the
ination cycle begins again. An icon will appear on the graphical display signalling
when the ination cycle is in progress. (See‘Pump Features’section) Pressure and the
inate/deate cycle are automatic and an alarm will be activated if the system is not
functioning properly. (See‘System Alarms’ section).
S Mode Operation (slow ination): The user has an option to select the S mode
button to switch to a slower ination mode. After selection, both cus begin to inate
simultaneously once every 60 seconds. The ination cycle is approximately 10 seconds
long. The aircells inate to a peak pressure of 45mmhg ±10%. In 50 seconds, the
ination cycle begins again. In S mode, pressures are automatic and alarms function
normally.
Intended Use/Indications
The VenaFlow Elite System is an intermittent pneumatic compression device that
is intended as a prophylaxis for deep vein thrombosis (DVT) in a clinical setting or
in the home. The VenaFlow Elite System is designed to be used only with VenaFlow
Elite cus.
Contraindications
The VenaFlow Elite System should not be used by persons with known or
suspected deep vein thrombosis, severe congestive heart failure, pulmonary
edema, thrombophlebitis, severe arteriosclerosis, or active infection. Do not
use on extremities which are not sensitive to pain, where cu will interfere
with gangrene, on patients with vein ligation or recent skin grafts, or extreme
deformity of the leg. Do not use the VenaFlow Elite System where increased
venous or lymphatic return is undesirable.

bed), bed rail, or rest on oor or table.
To use the telescoping bed hanger,
press release button on the back of the
device and gently pull out bed hook to
the desired width.
2) Connect tube assembly to the pump.
Make sure tubing connectors lock
securely into pump connectors.
3) Plug in the power cord to electrical
outlet.
Cu Application
The VenaFlow Elite System will automatically detect the cu that is attached to the
device and apply appropriate pressures. You must attach the cus prior to powering
on the device.
1) Calf cu – Apply cu with the tube pointed toward the foot. The aircell may be
placed either on the back, side or front of the leg.
It doesn’t matter where the aircell sits on the leg, it
will perform the same.
Foot cu – Apply cu with the aircell centered on bottom of foot and with the
tube pointed to the left. Foot cus are only for use in standard rapid
ination mode.
Thigh cu – Apply cu with the distal and proximal aircells centered on either the
back, side or front of the calf and thigh with the tube pointed toward the foot. It
doesn’t matter where the aircell sits on the leg, it will perform the same.
2) Connect cus to the tubing that is attached to the pump.
For varied patient sizes, trim calf and thigh cus as needed for proper t.
Be sure to secure cu straps snug but not tight. Once again, when using the calf cu
and thigh cu, rotation of the aircell on the leg does not aect performance of the system.

Lithium-Ion Battery Maintenance Guidelines
Overview
Do not leave batteries unused for extended periods of time because Lithium-Ion
batteries continue to slowly discharge (self-discharge) when not in use or while in
storage. Routinely check the battery’s charge status. The product Operator’s manual
includes information on how to check battery status as well as battery charging
instructions. When a battery has been unused for 6 months, check the charge status
and charge or send the system back to DJO for battery replacement.
The typical estimated life of a Lithium-Ion battery is about two to three years or
300 to 500 charge cycles, whichever occurs rst. One charge cycle is a period of use
from fully charged, to fully discharged, and fully recharged again. For batteries that do
not run through complete charge cycles, there is a two to three year life expectancy.
The intended operating temperature of the device is between 0 and 50 °C.
Rechargeable Lithium-Ion batteries have a limited life and will gradually lose their
capacity to hold a charge. This loss of capacity (aging) is irreversible. As the battery
loses capacity, the length of time it will power the product (run time) decreases.
Battery Maintenance
You should routinely check the battery’s charge status. Carefully monitor batteries that
are approaching the end of their estimated life. Consider shipping the device back to
DJO to replace the battery if you note either of the following conditions:
1. The battery run time drops below about 80% of the original run time.
2. The battery charge time increases signicantly.
If a battery is stored or otherwise unused for an extended period, be sure to follow the
storage instructions in this document. If you do not follow the instructions, and the
battery has no charge remaining when you check it, consider it to be damaged. Do not
attempt to recharge it or to use it. Send the system back to DJO for replacement.
Charging
Always follow the charging instructions provided in your Operator’s manual.
Storage
Charge or discharge the battery to approximately 50% of capacity before storage.
Charge the battery to approximately 50% of capacity at least once every six months.
The battery is best stored at 20±5 °C. For periods of less than 1 month, the battery can
be stored between -20~45 °C.
NOTE: The battery self-discharges during storage. Higher temperatures (above 20 °C
or 68 °F) reduce the battery storage life.
7) Select the button under ‘Done’ to set the new conguration. The change is
complete and the system is ready to operate. A“C”will appear on the display
indicating that the compliance alarm is enabled.

12 13
Low Battery Alarm
1) When there is approximately 15 minutes of charge left in the
battery, an audible alarm will beep 3 times every minute.
When there is less than approximately 5 minutes of charge
left, a consistent beep will sound and a larger version of the
battery icon will appear on the graphical display and it will
alternate with the text“LOW BATTERY”.
2) When either battery alarm occurs, immediately plug device in to electrical outlet
to begin replenishing the charge.
3) If the device is not plugged in during the alarm period, the device will shut down
and will fail to power on again until the device is plugged in again.
Installing or Replacing the Battery
1) Remove power cord. Refer to the ‘Instructions for
installing/removing/replacing the power cord’ section.
2) Remove back cover of device by removing 4 screws
using TORX (star) T20 driver.
