Benefits of Low Air Loss Mattress: How It Works and Selection Tips

- Burn patients: These mattresses remove excess moisture from wound exudates, reducing the need for frequent nursing interventions for skin care, repositioning, or hygiene, allowing staff to focus on more critical needs of patients and their families.3
- Patients with obesity: 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.4 Low Air Loss mattresses help manage these issues by optimizing pressure redistribution and microclimate control, which is essential for patient comfort and skin health.
- Patients with damp skin due to sweating, incontinence, or fever can benefit from a surface that effectively manages moisture.5 Proper skin microclimate management can increase tolerance to mechanical loading, reducing tissue deformation and the risk of pressure injuries.
- Pressure redistribution
- Friction and shear management
- Microclimate management
- Pressure Redistribution: The Serene Air system features both alternating and static modes. The alternating mode provides pressure redistribution through cyclic changes in loading and unloading (i.e., inflation and deflation of air-filled cells), while the static mode ensures proper immersion and envelopment to maximize pressure redistribution of the skin tissue in contact with the mattress. This design enhances user comfort and reduces the risk of pressure injuries.
- Friction and Shear Management: The seat inflation mode of Serene Air provides adequate postural support to prevent shear in the coccyx, sacrum, and buttocks.7 Additionally, Wellell's top cover offers low shear and low friction while providing optimal immersion and envelopment, further protecting these vulnerable areas.
- Microclimate Management: The Serene Air system, equipped with a powerful blower system (over 1,300 lpm), delivers reliable True Low Air Loss, ensuring effective microclimate control and improving patient outcomes. The top cover also boasts a moisture vapor transmission rate (MVTR) greater than 500 g/m²/24 hrs, ensuring high moisture vapor permeability.

FAQs About Low Air Loss Mattresses
Q1. Do I have to turn patients on a low air loss mattress?
Yes. While it helps reduce pressure, patients still need regular turning to prevent pressure ulcers and support circulation.
Q2. What is the difference between a low air loss mattress and an air fluidized mattress?
Low air loss uses airflow to reduce moisture and pressure. Air fluidized beds use beads and air to create a fluid-like surface for advanced wound care.
Q3. Can a low air loss mattress be used at home?
Yes. Many models are designed for home use and can help manage or prevent pressure ulcers in home care settings.
Q4. Should I put sheets on a low air loss mattress?
Use only light, breathable sheets. Thick bedding can block airflow and reduce the mattress's effectiveness in pressure relief and moisture control.
