What Is a VAC Dressing Therapy
Machine?
A VAC Dressing Therapy Machine is
a medical device used for Negative Pressure Wound Therapy (NPWT). It applies
controlled sub-atmospheric pressure to a wound through a sealed dressing,
helping remove excess fluid and stimulate tissue healing.

Why Was VAC Therapy Developed?
Traditional wound dressings often
struggle with:
- Excess exudate
- Poor blood circulation
- High infection risk
- Slow granulation tissue formation
VAC therapy was developed to:
- Improve blood flow
- Reduce edema
- Remove infectious material
- Promote faster wound closure
How Does VAC Dressing Therapy
Work? (Working Principle)
VAC therapy works on the
principle of controlled negative pressure.
Step-by-Step Working:
- Foam or gauze dressing is placed in the wound
- Dressing is sealed with an adhesive drape
- A suction tube connects dressing to VAC pump
- Negative pressure is applied continuously or
intermittently
- Fluid is removed into a collection canister
- Micro-deformation stimulates granulation tissue
This environment promotes faster,
cleaner healing.
