What does the low air loss therapy aim to control?

1. Patient mobility

2. Skin heat and humidity

3. Blood flow and circulation

4. Pressure points on the body

The correct answer is: Skin heat and humidity

Low air loss therapy aims to control skin heat and humidity by providing a specialized support surface that allows air to circulate beneath the patient. This type of therapy is designed to enhance the microclimate around the skin, which helps to reduce moisture buildup and excessive heat. Maintaining a balanced environment can prevent the development of pressure ulcers, as both moisture and heat can contribute to skin breakdown. In this context, the specific focus of low air loss therapy aligns directly with preserving skin integrity by managing the thermal and moisture conditions of the skin surface, alleviating discomfort, and promoting healing in patients at risk for pressure injuries.
