If you experience any pain, swelling, sensation changes, or any unusual reactions while using this product, consult your medical professional immediately. Do not overinflate aircells. Improper aircell inflation may cause significant irritation in patients with diabetic neuropathy. Reduce aircell compression with any visual skin changes or reported discomfort. Do not use this device on patients incapable of communicating physical discomfort. Like all lower extremity immobilizers, such as casts or braces, patients without sensation (ie: post-op anesthesia, neuropathies, etc.) should be monitored frequently for “hot spots”, skin irritation or wound management. Use caution when walking on slippery or wet surfaces to avoid injury. At high altitudes the aircells will expand beyond optimal level. Adjust aircell pressure by tightening or loosening straps. Always consult with your physician or therapist before making changes to the brace. Always inspect before use. Check for broken stitches or parts; torn, cut or frayed material; or buckles, or hook and loop fasteners that do not hold securely. Do not use damaged product. Discontinue use when torn, worn, frayed in any way. Never alter or repair this product. This product is not intended to be used with any other product except DJO approved accessories.
