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

In the context of vacuum-assisted closure (VAC) therapy, the primary goal is to promote wound healing by applying negative pressure to the wound site. This technique helps to remove exudate, reduce edema, and increase blood flow, thereby facilitating the healing process.

For effective VAC therapy, the negative pressure setting is typically maintained at an ideal pressure of -125 mm Hg. This level of suction is clinically validated to provide optimal healing conditions by encouraging the formation of granulation tissue and helping approximate wound edges, which are essential components of the healing process.

Thus, among the provided options, the correct pressure setting for VAC therapy is:

• -125 mm Hg
