Warnings and Precautions

Sterility is guaranteed unless pouch is damaged or opened prior to use.
This wound dressing should not be used with other wound care products without first consulting a health care professional.
During the body's normal healing process, non-viable tissue (autolytic debridement) is removed from the wound, which could make the wound appear larger after the first few dressing changes. If the wound continues to get larger after the first few dressing changes, consult a health care professional.
Should you observe irritation (reddening, inflammation), maceration (whitening of the skin), hypergranulation (excess tissue formation) or sensitivity (allergic reaction), consult a health care professional.
Frequent dressing changes on wounds with damaged or delicate sin surrounding the wound are not recommended. The wound should be inspected during dressing changes. Contact a health care professional if (1) signs of infection occur (increased pain, bleeding, wound drainage), (2) there is a change in wound color and/or odor, (3) the wound does not begin to show signs of healing and/or (4) any other unexpected symptoms occur.
The dressing may be used on infected wounds only under the care of a health care professional.
The use of this dressing neither guarantees nor warrants against AIDS or Hepatitis B Virus transmission.

Mode of Use/Application

Before using the dressing, clean the wound with an appropriate wound cleansing agent or normal saline and dry the surrounding skin. Choose a dressing size and shape to ensure that the dressing is 3cm larger than the wound area in any one direction. Remove the release paper from the back, being careful to minimize finger contact with the adhesive surface. Hold the dressing over the wound and line up the center of the dressing with the center of the wound. Place the dressing directly over the wound. For difficult-to-dress anatomical locations, such as the heel or sacrum, a supplementary securing device, such as tape, may be required. Discard any unused portion of the product after dressing the wound.

Removal & Change Frequency

The dressing should be inspected frequently for leakage, rolling of the edges and/or whether any part of the bubble has reached the change indicator. If any of these occur, the dressing should be changed. As wound fluid is absorbed by the dressing, gel formation may be visible through the dressing. The dressing should be changed when clinically indicated, when strikethrough occurs or a maximum of seven days after application. The wound should be cleansed at appropriate intervals. Press down gently on the skin and carefully lift one corner of the dressing until it is no longer adhered to the skin. Continue until all edges are free. Carefully lift away the dressing.
