V.A.C.®THERAPY CLINICAL APPLICATIONS

Indications: Indicated for patients who would benefit from a sub atmospheric pressure device particularly as the device may promote wound healing. This includes patients who would benefit from vacuum assisted drainage and removal of infectious material or other fluids from wounds under the influence of continuous and/or intermittent sub atmospheric pressure. Types of wounds for which V.A.C.®Therapy has been indicated include chronic, acute, traumatic, sub acute and dehisced wounds, partial - thickness burns, diabetic ulcers, pressure ulcers, flaps and grafts. Contraindications: Contraindicated for patients with malignancy in the wound, untreated osteomyelitis, unexplored fistulas, non-enteric fistulas, or necrotic tissue with eschar present. Do not place V.A.C . dressing over exposed blood vessels or organs. Precautions: Always Follow Universal Precautions Precautions should be taken with patients exhibiting active bleeding, difficult wound hemostasis, or who are on anticoagulants. When placing the V.A.C. dressing in proximity to blood vessels or organs, take care to ensure that they are adequately protected with overlying fascia, tissue or other protective barriers that form a complete barrier between them and the V.A.C. foam dressing. Greater care should be taken with respect to weakened, irradiated or sutured blood vessels or organs. Bone fragments or sharp edges could puncture a barrier, vessel or organ. Wounds with enteric fistulas may require special precautions in order to optimize V.A.C. Therapy. Refer to the V A. C. Therapy Clinical Guidelines for sample guidelines additional information on clinical applications and therapy considerations. For recommended protocols, please consult the treating physician.

Federal law restricts this device to sale or rental by or on the order ofa physician.

V.A. G. @ A TS Operations and Maintenance Manual

V.A.C. ® THERAPY CARE AND SAFETY TIPS KEEP THERAPY ON Never leave sub atmospheric pressure off for more than 2 hours per day. Remove VAC.® dressing if subatmospheric pressure is terminated or is off for more than 2 hours per day. DRESSING CHANGES Perform aggressive wound cleaning per physician order prior to dressing application. Routine dressing changes should occur every 48 hours. Dressing changes for infected wounds should be accomplished every 12-24 hours. Always replace with sterile VAC. disposables from unopened packages. Follow established institution protocols regarding clean versus sterile technique. Note: All components of The VAG. System are packaged sterile. The decision to use clean versus sterile/aseptic technique is dependent upon wound pathophysiology and physician/clinician preference. All VAC. Therapy disposables (including the foam, canister, tubing and drape) are latex free. MONITORING THE WOUND Inspect the dressing frequently to ensure foam is collapsed and negative pressure is being delivered in a consistent manner. Monitor periwound tissue and exudate for signs of infection* or other complications. Extra care and attention should be given if there are any signs of possible infection or related complications. Infection can be serious. With or without V.A.C. Therapy, infection can lead to many adverse complications including pain, discomfort, fever, gangrene, toxic shock, septic shock and various other complications. IF DRESSING ADHERES TO WOUND Instill normal saline into the dressing and let it set for 15-30 minutes, then gently remove the dressing from the wound. Consider placing a single-layer, wide-meshed, non-adherent dressing prior to foam placement. DISCOMFORT If patient complains of discomfort throughout therapy, consider changing to white PVA Versa Foam™ dressings. If patient complains of discomfort during the dressing change, consider pre-medication , use of a non-adherent prior to foam placement or instillation of a topical anesthetic agent such as 1% lidocaine without epinephrine prior to dressing removal. UNSTABLE STRUCTURES Over unstable body structures such as unstable chest wall or non-intact fascia, use continuous (not intermittent) therapy to minimize movement and stabilize the wound bed. SPINAL CORD INJURY In the event a patient experiences autonomic hyperreflexia (sudden elevation in blood pressure or heart rate in response to stimulation of the sympathetic nervous system) discontinue VAC. Therapy to help minimize sensory stimulation. BODY CAVITY WOUNDS Underlying structures must be covered by natural tissues or synthetic materials that form a complete barrier between the underlying structures and the VAC. foam dressing. V.A.C. DISPOSABLES The VAC .® ATS therapy unit is to be used exclusively with VAC. ® disposables. WARNING: Do not pack the foam into any areas of the wound. Forcing foam dressings in a compressed manner into any wound is contrary to KCI recomme ndations. 'Signs of possible infection may include fever, tenderness, redness, swelling, itching, rash, increased wannth in the wound area, purulent discharge or a strong odor. Nausea, vomiting, diarrhea, headache, sore throat with swelling of the mucous membrane, disorientation, high fever (> I 02F, 38.8 C), refractory hypotension, orthostatic hypotension, or erythroderma (a sunburn-like rash) may be added signs of more serious complications of infection.

1. Perform aggressive wound care per physician order prior to V.A.C. ® Dressing application . 2. Cut the V.A.C. ® foam to fit the size and shape of the wound, then place the foam (a) into the wound cavity. Avoid cutting foam directly over wound to prevent particles from entering wound bed. Warning: do not pack the foam into any areas of the wound. Forcing foam dressings in a compressed manner into any wound is contrary to KCI recommendations.

3. Size the drape to cover the foam and 3-5 cm of surrounding intact skin. Trim drape if necessary. Remove the white backing liner (labeled 1) and place drape on foam. Remove top support layer (labeled 2) and pat around drape to ensure an occlusive seal.

4. Choose a location on the drape where you would like to apply the tubing. At this location, cut a hole through the drape, approximately 2 cm in diameter, leaving the foam mostly intact. An alternative is to cut a 2 cm diameter hole into the drape before you lay it down on the foam. Either process of cutting the drape will work. Note: Always cut a 2cm hole in the drape. Do not cut a linear "slit" in the drape. When negative pressure is applied, a slit may collapse and close, preventing negative pressure from reaching the wound

5. Remove the backing liner (labeled 1) from the T.R.A.C.TM Pad. Place the T.R.A.C. Pad on the drape, with the hole in the center of the T.R.A.C . Pad elbow directly over the hole in the drape. Gently pat around the T.R.A.C. Pad to ensure complete adhesion. Remove the support layer (labeled 2).

6. Remove the blue handles from the drape and T.R.A.C. Pad, where applicable. Connect dressing tubing to canister tubing.

7. Refer to page 9 for canister installation. NOTE: DO NOT Cut off the T.R.A.C. Pad and insert the T.R.A.C. tubing into the foam . This will cause the therapy unit to alarm
