True low air loss improves skin microclimate management and pressure injury prevention
Improper skin microclimate management reduces tolerance to mechanical loading.
Microclimate refers to the temperature, humidity and airflow next to the skin surface. With an increase in temperature and humidity, the skin becomes weaker (more vulnerable) and less stiff. Improper skin microclimate management reduces tolerance to mechanical loading, increasing tissue deformation and pressure injury risks.1
A low air loss support surface is a critical tool in care of the acute care burn and obese patients.
Low air loss describes a feature where air is circulated beneath a water vapor permeable cover to control the humidity at the interface between the individual and the support surface. Low air loss support surfaces provide airflow to assist in managing the heat and humidity (microclimate). The low air loss bed system offers many advantages in the care and management of the burns patient, for example, it removes excess moisture when a burn patient’s wounds excrete fluid. There is a definite saving of nursing time by rendering unnecessary constant attention to the patient for preventative skin care, positioning, bed pan etc. The nurse is then able to devote her time positively to the more involved needs of the patient and family. 2 People with obesity are also at increased risk of stress incontinence and diaphoresis, as well as heat and moisture trapping between the body and the support surface. A support surface that optimizes pressure redistribution and microclimate control is required. 1
Serene Air’s blower provides reliable True Low Air Loss to optimize heat and moisture reduction at the interface.
Support surfaces featuring low air loss are commonly used for postoperative patients to prevent the developing and worsening of new and existing pressure injuries. 1 Serene Air’s blower (>1,300 lpm) provides reliable True Low Air Loss, ensuring proper skin microclimate management and improving clinical outcomes.
- Helps reduce moisture between patient and the lying surface
- Helps regulate the skin’s temperature and improve patient’s comfort (Maceration)
- Less susceptible to the damaging effects of pressure and shear forces
- Suitable for burn and very high risk patients
