What is a Wound VAC?

Negative Pressure Wound Therapy, also known as a vacuum-assisted closure, is a therapeutic technique using a suction pump, tubing and a dressing to remove excess exudate and promote healing in acute or chronic wounds and second- and third-degree burns.

Negative pressure wound therapy or NPWT is a way of drawing out fluid and infection from a wound in order to heal it. This therapy is carried by using a special dressing (bandage) which is sealed over the injury, and an attached gentle vacuum pump.

What types of wounds need NPWT?

In cases of burns, pressure ulcers, chronic wounds, diabetic foot ulcers, and injuries, your doctor may advise you to go for NPWT. The therapy is well known for its fast healing properties with minimum infection risk. Despite its several benefits, NPWT should not be used without the doctors' prescription. Your physician will recommend a suitable kind of treatment depending on the type of wound and your medical health. A wound vac is often used for:

• Acute and chronic wounds
• Traumatic wounds
• Surgical wounds
• Chronic burns
• Tunneling wounds
• Partial thickness burns
• Neuropathic and diabetic wounds
• Pressure ulcers
• Post C-section
• Skin grafts/muscle flaps
• Dehisced wounds

• Fragile skin
• Untreated osteomyelitis 
• Malignant wounds
• Nonenteric and unexplored fistulas
• Exposed organs or blood vessels
• Necrotic tissue with eschar present 

Benefits of Wound VAC

NPWT helps treat various wounds, and the potential benefits include the following:

• Reduces swelling and inflammation 
• Decreases risk of bacterial infection 
• Improves blood flow to the wound
• Promotes granulation tissue formation 
• Provides a closed and moist wound-healing environment 
• Helps remove infectious materials
• Protects wounds from the outside environment 
• Gentle pulling together of the wound’s edges
• Less dressing changes compared with the other treatments

How does Wound VAC Machine work?

NPWT helps treat various wounds, and the potential benefits include the following:

To use NPWT, the following things are required:

• A special dressing or bandage.
• A tubing.
• A negative pressure device.
• A canister for collecting fluids.

1. Various layers of foam dressing are applied to the wound. Then the dressing is sealed properly using a medical film.
2. There is a tube attached to the film's opening, which leads to the vacuum pump and canister.
3. The canister is used to collect fluids. You can either set the pump to either work continuously or intermittently.
4. The vacuum pump sucks out the fluid and the infection from the wound and helps make the healing faster.
5. It also helps in pulling the edges of the wound and promoting the growth of newer tissues.
6. If and when required, you can push the antibiotics and saline into the wound.

Things to consider while using a Portable Wound VAC

There are certain things one needs to keep in mind while using a VAC device such as -

• Wounds take time to heal depending on plenty of factors such as the wound's size, location, depth, and nutritional status.
• Showering with NPWT device on - You can easily disconnect the aid and shower. However, the device should be off for not more than 2 hours a day.
• Bathing with a wound is tricky as bathing water (soap water) may increase your wound's chances of getting infected. Additionally, it can also make the dressing lose, and water can get inside the wound dressing, worsening your situation.
