Question

What is the ideal pressure setting for vacuum-assisted closure (VAC) therapy?

• A. -125 mm Hg
• B. 60 to 80 mm Hg
• C. 130 mm Hg
• D. 80 to 100 mm Hg

Hint:

For VAC therapy, the optimal pressure is -125 mm Hg, which maximizes wound healing while minimizing the risk of tissue injury.

Answer 1

The Correct Option is A

Vacuum-assisted closure (VAC) therapy, also known as negative pressure wound therapy (NPWT), is used to promote wound healing by applying controlled negative pressure to the wound. The ideal pressure setting for VAC therapy is typically -125 mm Hg, as this pressure has been found to be the most effective in promoting wound contraction, increasing blood flow, and enhancing tissue granulation without causing damage to the tissue.
- Option (2) (60 to 80 mm Hg) is often too low and may not provide optimal therapeutic benefits.
- Option (3) (130 mm Hg) is higher than the standard setting and may increase the risk of tissue damage.
- Option (4) (80 to 100 mm Hg) is also lower than the optimal setting and may not provide the most effective therapeutic pressure.
Thus, the ideal pressure setting for VAC therapy is -125 mm Hg.
