What does low air loss therapy aim to control?

1. Patient movement

2. Skin temperature and humidity

3. Overall patient comfort

4. Pressure distribution

The correct answer is: Skin temperature and humidity

Low air loss therapy is primarily designed to manage skin temperature and humidity. This type of therapy utilizes a mattress or support surface that maintains a controlled microclimate around the patient, which is crucial for individuals at risk of developing pressure ulcers or those who already have them. By introducing a continuous flow of air through the support surface, the therapy helps to dissipate moisture and excess heat that can lead to skin maceration. Maintaining an optimal environment around the skin can significantly enhance healing and comfort for patients, making it easier to manage wounds effectively. This balanced control of moisture and temperature not only helps prevent skin breakdown but also supports the healing process by promoting a healthier microbial environment. Therefore, low air loss therapy's primary aim is indeed the control of skin temperature and humidity to protect and heal the skin effectively.
