CWCA Advanced Wound Therapies Flashcards

Negative Pressure Wound Therapy (NPWT) promotes wound healing primarily by:

Answer: Removing excess exudate and promoting granulation tissue formation

NPWT uses sub-atmospheric pressure to remove exudate, reduce edema, and stimulate angiogenesis and granulation tissue formation.

Which of the following is a contraindication for Negative Pressure Wound Therapy (NPWT)?

Answer: Wound with untreated osteomyelitis

NPWT is contraindicated in wounds with untreated osteomyelitis because negative pressure can spread infection into bone or surrounding tissue.

The standard negative pressure setting for NPWT in most clinical applications is:

Answer: -75 to -125 mmHg

Most NPWT protocols use -75 to -125 mmHg, with -125 mmHg being the most commonly used therapeutic pressure.

Hyperbaric Oxygen Therapy (HBOT) for chronic wounds works by:

Answer: Delivering high concentrations of oxygen under increased atmospheric pressure to hypoxic tissue

HBOT increases dissolved oxygen in plasma under pressure, delivering oxygen to hypoxic wound tissue where hemoglobin-bound oxygen cannot reach.

Biological skin substitutes used in chronic wound care are best indicated for:

Answer: Full-thickness wounds failing to progress with conventional therapy

Bioengineered skin substitutes are indicated for non-infected, clean full-thickness wounds that have not healed adequately with standard wound care.

Which dressing type uses electrical current to promote wound healing and reduce biofilm?

Answer: Bioelectric dressing

Bioelectric dressings generate low-level electrical current that disrupts bacterial biofilm and stimulates tissue repair processes.
