Therapeutic Advantages of Low Air Loss Mattress System

Therapeutic Advantages of Low Air Loss Mattress System

There is a growing population of patients who are bed-bound or who spend a considerable amount of time in the bed. If using a conventional bed, the body heat and moisture get trapped causing skin breakdown and rashes, leading to sores and ulcers. The prevention and treatment of pressure sores lie in using the therapeutic low air loss mattress system which is clinically effective, durable, reliable and affordable.

How does the low air loss mattress system work?

A low air loss mattress has tiny laser made air holes in its top surface which continually blow out air causing the patient to float. This reduces skin interface pressure at the mattress surface. As a result, moisture is wicked away and the patient stays dry. This is an excellent therapeutic environment for the prevention and treatment of stages 1 to 4 pressure ulcers.

An important point to remember is the layer of bedding between the mattress and the user should be minimum.

The Huntleigh Breeze Low Air Loss Mattress Replacement System, provides excellent pressure redistribution. It is highly recommended for the prevention and management of heel ulcers. This is facilitated by its unique turn valve deflation feature which allows key cells to be deflated under the heels.

Likewise, the Invacare True Low Air Loss Therapeutic Support Mattress wicks away moisture and heat and maintains a moderate environment for the user. The healing environment is perfect for stages 1 to 4 ulcers. It is available in both standard and bariatric sizes.

How does the alternating pressure system work?

Alternate inflation and deflation of cells change pressure points and improves blood circulation. A single cell deflates and re-inflates and then the adjoining cell and so on, slowly, up and down the mattress. The head area of the mattress does not move and so the patient stays undisturbed even while asleep. The speed at which the alternating process moves from one end of the mattress to the other can be adjusted by the patient.

How does the dual therapy mattress work?

Combination low air loss and alternating pressure mattress systems are also available. They have an alternating pressure base with a low air loss top cover. Such a system requires high powered pumps and blowers to be able to supply the true air loss.

Dual therapy mattress system for bariatric bed-bound patients

Bariatric patients are at a greater risk of pressure sore because of their size and immobility. The low air loss, alternating pressure mattress, is very useful in managing multiple stage 3 or 4 wounds. In case of bariatric patients, a higher volume airflow is required to counteract the increased perspiration. This will also maintain adequate airflow to alternate pressure in the mattress.

Wound therapy using low air loss mattress system

Using low air loss mattresses for wound therapy can significantly reduce the recovery time and rate of complication. This is because low air loss mattresses regulate and manage moisture levels. They also immerse the patient into their surface when compared to a conventional bed, wherein the patient stays on the surface only. The healing time is determined by the blood flow to the wound site. A low air loss mattress maximizes the contact area and regulates the pressure levels, thereby improving blood flow to the wound site.

Points for consideration

  • The blower motor and pump should support round the clock use. Motors that use air that is already in the cells are advisable rather than those which circulate the outside air.
  • The mattress should allow for adequate pressure redistribution of the patient’s weight. So, it is essential that the patient is enveloped by the mattress to some extent rather than just being on the top of its surface.
  • In case of bariatric patients, the mattress should be specifically suited for bariatric weight load.
  • The mattress should match with the bed in terms of its fit and size.
  • The mattress cover should be loose, water-resistant and vapor permeable. It should also be fire-resistant and hypoallergenic.
