�� Text on screen: This video is intended for clinicians. The ActiV.A.C.� Therapy System is an integrated negative pressure wound management system for use in acute, extended and home care settings. When used on open wounds, it is intended to create an environment that promotes wound healing by secondary or tertiary (delayed primary) intention by preparing the wound bed for closure, reducing edema, promoting granulation tissue formation and perfusion, and by removing exudate and infectious material. Open wound types include chronic, acute, traumatic, subacute and dehisced wounds, partial-thickness burns, ulcers (such as diabetic, pressure or venous insufficiency), flaps and grafts. When used on closed surgical incisions, it is intended to manage the environment of surgical incisions that continue to drain following sutured or stapled closure by maintaining a closed environment and removing exudate via the application of negative pressure wound therapy. Prior to use of the ActiV.A.C.� Therapy System, consult the product instructions for use and safety information provided with the device. Additional safety information specific to the ActiV.A.C.� Therapy System is available at the end of this video. Contact your local 3M representative if you have any questions before initiating therapy. Text on screen: 3M� ActiV.A.C.� Therapy System Clinician Instructional Video.

V.A.C.� Therapy in the absence of instillation is intended to create an environment that promotes wound healing by secondary or tertiary (delayed primary) intentions by preparing the wound bed for closures, reducing edema, promoting granulation tissue formation and perfusion, and by removing exudate and infectious material. Veraflo Therapy is indicated for patients who would benefit from vacuum assisted drainage and controlled delivery of topical wound treatment solutions and suspensions over the wound bed. The V.A.C.� Ulta Therapy System with and without instillation is indicated for patients with chronic, acute, traumatic, sub-acute and dehisced wounds, partial thickness burns, ulcers (such as diabetic, pressure and venous insufficiency), flaps and grafts. V.A.C.� Therapy in the absence of instillation may also be used for: The temporary bridging of abdominal wall openings where primary closure is not possible and/or repeat abdominal entries are necessary and for open abdominal wounds with exposed viscera including, but not limited to, abdominal compartment syndrome. The intended care setting is a closely monitored area within the acute care hospital, such as the ICU. The abdominal dressing will most often be applied in the operating theater. The management of the environment of surgical incisions that continue to drain following sutured or stapled closure by maintaining a closed environment and removing exudate via the application of negative pressure wound therapy.

Refer to Warnings, Bleeding section in the V.A.C.� Therapy System Safety Information and V.A.C.� Granufoam� Dressing Application Instructions. A medical professional tends to a wound on a practice mannequin on an operating table in a hospital setting. The medical professional removes existing dressing from the wound. The medical professional inspects the wound and cleans it according to institutional protocol. Before applying a new dressing, remove and discard the previous dressing per institution protocol. Thoroughly inspect the wound to ensure all pieces of dressing components have been removed. Perform a thorough wound and periwound area cleaning per physician order or institution protocol prior to each dressing application. Ensure adequate hemostasis has been achieved. j& Text on screen: V.A.C.� Dressing Application for Single Wounds. A medical professional tends to a wound on a practice mannequin's foot on an operating table. The medical professional opens a packet of 3M� Cavilon� No Sting Barrier Film and applies it to the periwound skin. Text on screen: Note: If adjunct materials are utilized under the V.A.C.� Dressing, they must be meshed or fenestrated to allow for effective exudate removal and negative pressure delivery. Record the total number of pieces of foam used in the wound and document this on the Foam Quantity Label and in the patient's chart. The medical professional uses scissors to cut a hole in the middle of the V.A.C.� Drape. They place the hole in the drape directly over the wound and peel back layers of adhesive backing. They gently press the adhesive into place. Shown here is a small wound requiring a standard V.A.C. dressing. Prepare the periwound area by applying a protective skin barrier preparation, such as 3M� Cavilon� No Sting Barrier Film. j& Picture frame or window pane the wound with a hydrocolloid dressing, or another vapor-permeable adhesive film dressing, such as V.A.C. Drape, or 3M� Tegaderm� Transparent Film Dressing. (crinkling) j& The medical professional uses scissors to cut a piece of dressing foam to a desired size. Text on screen: Do not cut the foam over the wound, as fragments may fall into the wound. Away from the wound site, rub foam edges to remove any fragments or loose particles that may fall into or be left in the wound upon dressing removal. The medical professional continues to cut the foam away from the wound and gently rubs the edges to remove any excess. Cut dressing foam to dimensions that will allow the foam to be placed gently into the wound, but not overlap onto intact skin. j& Text on screen: Assure the foam does not extend onto intact skin, that it is positioned on the product used to "picture frame" the wound and protects the intact skin. Note: Ensure foam-to-foam contact between adjacent pieces of foam for even distribution of negative pressure. Do not force dressing foam into any area of the wound. The medical professional places the foam into the wound cavity. The medical professional places a larger, circular piece of foam over the first piece of foam in the wound. Gently place the foam into the wound cavity, ensuring contact with all wound surfaces. To accommodate the size of the SensaT.R.A.C.� Pad, cut another piece of foam large enough to extend two- to three-centimeters beyond the SensaT.R.A.C.� Pad, and lay the foam in the wound. j& Text on screen: Drape application. The medical professional peels an adhesive backing off of the drape and places it over both pieces of foam. They gently press down to secure the drape to the surrounding skin. Text on screen: Note: Patient's skin condition should be carefully monitored. The medical professional continues to remove layers of adhesive backing and gently presses the drape into place over the skin, ensuring a seal. Trim and place the drape to cover the foam dressing and an additional three- to five-centimeter border. j& (crinkling) j& Text on screen: SensaT.R.A.C.� Pad Application. The medical professional pinches the V.A.C.� Drape and cuts a small hole over the foam. Text on screen: Cut a hole, not a slit. Note: Do not cut off the pad or insert the tubing directly into the foam dressing. This may occlude the tubing and cause the V.A.C.� Therapy Unit to alarm. Pinch the V.A.C. drape and carefully cut an approximately 2.5-centimeter hole, not a slit, through the V.A.C. drape. The hole should be large enough to allow for removal of fluid and exudate. You do not need to cut into the foam. j& The medical professional holds the SensaT.R.A.C.� Pad over the wound area as they prepare to apply it. They remove two backing layers and place the adhesive side of the pad directly over the hole in the drape. Text on screen: Note: To prevent periwound maceration with wounds that are smaller than the central disc of the pad, it is very important that the central disc lay on top of foam only. It may be necessary to augment the V.A.C.� Dressing that is in the wound with an additional piece of foam cut 1-2cm larger than the diameter of the central disc. If this is used, please ensure the periwound skin is protected prior to foam augmentation. The medical professional gently presses down on the SensaT.R.A.C.� Pad to secure it to the dressing. Text on screen: Please refer to the V.A.C.� Therapy Clinical Guidelines for additional dressing application techniques. The medical professional pulls on a blue tab on the SensaT.R.A.C.� Pad to remove the pad stabilization layer. They gently press down on the drape to secure it to the area.
