Wound, Ostomy and Continence Nurses Society (WOCN) Practice Exam

What is the primary function of air fluidized therapy?

1. To increase patient mobility

2. To create a fluid medium for immersion

3. To apply constant pressure on the wound

4. To promote muscle strength in patients

The correct answer is: To create a fluid medium for immersion

The primary function of air fluidized therapy is to create a fluid medium for immersion. This therapy involves the use of a specialized mattress that contains tiny beads, which are aerated by a stream of air. When the air flows through the beads, it creates a fluid-like environment that reduces pressure and friction on the patient's skin. This immersion helps in managing pressure ulcers, as it disperses body weight evenly, decreases localized pressure, and enhances blood flow to the affected areas. The immersion effect provided by air fluidized therapy allows for better wound healing and reduces the risk of new pressure injuries. While the therapy may indirectly affect patient mobility and skin integrity, its primary design centers on providing a supportive surface that mimics the properties of fluid to alleviate pressure on vulnerable body parts.
