1. Safety Information
• Please do not dismantle any part of the system. Please contact the vendor if any repairs are required.
• In order to prevent damage to the device, please do not twist or bend the water lines.
• Avoid puncturing the sleeves and tubing. If any defects or blemishes are found in the sleeves and tubing, please cease use.
• ProMax-900 could be cold enough to seriously damage skin.
• ProMax-900 could reach pressure high enough to damage muscle and blood vessels. Please use the device with caution.
• Many device functions can be manually controlled, the user must stay alert and sober while operating.
• The air pump system is semi-manual, amount of pressure and options to inflate or deflate are mainly controlled by the user.
For the sake of safety, please cease use of the device in the event of numbing or lack of sensation in the affected limbs.
• Wrap deflation: Turning off the system will automatically open the air-release valve and release air from the wrap.
• Improper placement or prolonged use of ProMax-900 could result in tissue damage from frostbite or inhibited blood circulation.
Please be attentive while using this device.
• During ProMax-900 treatment, patients should monitor the skin surrounding the treated region or the digits of the extremities of the
treated limb for any burning, itching, increased swelling, or pain. If any of these signs are present, or any changes in skin
appearance occur (such as blisters, increased redness, discoloration, or other noticeable skin changes), patients
are advised to discontinue use and consult a physician.
• ProMax-900 sleeves are not sterile; do not place directly against open wounds, sores, rashes, infections, or stitches. May be applied
over clothing or dressing.
• ProMax-900 should be used only under the supervision of a licensed healthcare practitioner in users:
-Who have a wound in the affected region (the wound must be dressed prior to use of ProMax-900).
- Who have an acute, unstable (untreated) fracture in the affected region.
- Who are children under 18 years old or patients who have cognitive disabilities or communication barriers, whether
temporary due to medication or permanent.
-Who have a cardiac insufficiency or congestive heart failure (with associated edema in the extremities or lungs).
- Who have a localized skin condition (e.g., dermatitis, vein ligation, gangrene, skin graft) in the affected region.
-Who have erysipelas or other active infections in the affected region.

2. Contraindications
Compression therapy (pneumatic compression) using ProMax-900 should not be used on patients who:
•Are in the acute stages of inflammatory phlebitis in the affected region
•Have significant arteriosclerosis or other vascular ischemic disease in the affected region
•Have a condition in which increased venous or lymphatic return is not desired in the affected extremity
(e.g., carcinoma)
•Have decompensated hypertonia in the affected region
•Have pre-existing deep vein thrombosis (DVT)
•Have presumptive evidence of congestive heart failure
Cryotherapy using ProMax-900 should not be used on patients who:
