Question

What is the negative pressure in VAC dressing?

• A. 60-90 mmHg
• B. 90-100 mmHg
• C. 120-130 mmHg
• D. 130-150 mmHg

Hint:

The optimal range for negative pressure in VAC dressing is 120-130 mmHg to effectively promote wound healing and tissue regeneration.

Answer 1

The Correct Option is C

The negative pressure in a Vacuum-Assisted Closure (VAC) dressing, also known as negative pressure wound therapy (NPWT), refers to the suction pressure applied to promote wound healing through increased blood flow and removal of exudates. The standard negative pressure range used in this therapy is typically 120-130 mmHg. This suction helps to draw the edges of the wound together and is effective in promoting healing by encouraging granulation tissue formation.

Given the options, the range of 120-130 mmHg is correct for the negative pressure applied in VAC dressing.
