Also known as a "wound vac"
A technique for treating acute and chronic wounds by using a sealed wound dressing attached to a vacuum pump.
The vacuum creates a<unk><unk>  gradient that draws out fluid and increases blood flow to the area.
Often applied to wounds that are expected to heal poorly, such as diabetic foot ulcers,<unk>  ulcers, or very large tissue defects.
High quality evidence exists for improved outcomes in the treatment of diabetic foot ulcers.
Poor quality or insufficient evidence suggests may improve treatment of bedsores, large tissue defects, or other wounds.
There is little evidence to suggest an increased risk of complications, so wound vacs are often applied to many other kinds of wounds.
