How Does a Low Air Loss Mattress Work?

A bed is a kind of furniture that we use to sleep, rest, relax and reprieve at the end of each day. Since bed is a place where we can get rid of stress and go to sleep, it’s heaven for us. However, the bed can be the source of anxiety and pain for patients confined to bed because of illnesses like pressure ulcers.

Pressure ulcers patients may suffer from mild discomfort to extreme pain while confined to bed. In that case, a low air loss mattress can be handy for the treatment of pressure wounds. Low air loss mattress works innovatively in treating ulcers, persistent pressure, bone, joint infections, etc. Well, you can know how this air bed works and related all other aspects throughout this article.

For What Is a Low Air Loss Mattress Known For?

What Is a Low Air Loss Mattress

A low air loss mattress is not just like a regular or conventional mattress. Basically, it’s a pressure-relieving mattress, also known as pressure mattresses, that aid in preventing and treating bed sores. A low air loss mattress is designed in such a way as to ensure optimal comfort by maintaining a comfortable position.

This type of mattress is constituted of multiple inflatable air tubes that periodically inflate and deflate to relieve skin pressure. This alternating action prompts proper air circulation and helps to treat, manage, and prevent pressure wounds. The inflatable air tubes also help to alleviate stress from bony prominence like shoulders, hips, elbows, and heels.

Using a low air loss mattress for speedy recovery from pressure ulcers and other pressure injuries can be very helpful. This mattress distributes the patient's body weight over a wide surface which helps to forbid skin breakdown. Its airflow system will help to keep optimal body temperature and moisture level.

How Does a Low Air Loss Mattress Work

A low air loss mattress is a unique air bed that helps decrease maceration and heat development by removing extra moisture. It is basically for those confined to bed for a long time or recovering from medical conditions like injury or surgery. A low air loss mattress or LAL mattress works through three main components, including air chambers, pumps, and mattress cover.

  • Air Chambers: Most air chambers are made of PVC or Nylon, and it is the inflatable cylinder of the air mattress. The air chambers are adjacent to the other air chambers, creating a seamless surface designed to support patients lying on mattresses
  • Pumps: Pumps are also known as blowers, and they help to fill the air chambers with air. Well, you will find certain pump options or an automatic pump option. You can adjust the air pump settings based on patients’ conditions
  • Cover: Modern air beds come with a cover on the above side of the air chambers. The cover helps to remove friction and also prevents shear. It also prevents the body moisture from reaching the mattress and also allows vapor to get in

A low air loss mattress has air holes made with laser over the bed surface that constantly blow out air. The blowing air keeps the patient floating on a soft air cushion. Air bed normally uses 100-150 liters of air per minute to maintain and manage skin moisture and temperature level.

When a patient lies down on a low air loss mattress, the air chambers gently switch between inflation and deflation. The air pressure change cycle is non-noticeable, and it basically happens every 10-25 minutes. It changes the person’s weight to prevent constant pressure on the fragile skin areas and also stimulates blood flow to the tissues.


Types of Low Air Loss Mattress

There are many types of low air loss mattresses available, and not all are suitable for pressure injury-related patients. Here we’ve discussed two different types of air beds and their workability in detail:

1. Huntleigh Breeze Low Air Loss Mattress Replacement System

This air mattress offers excellent pressure redistribution, and it is highly effective in preventing and managing heel ulcers. Huntleigh breeze low air loss mattress has a unique turn valve deflation feature, allowing the heel cells to deflate. This air mattress has eight torso section cells which are effective to support the patient’s heavy body parts.

2. Invacare True Low Air Loss Therapeutic Support Mattress

Invacare true low air loss therapeutic support mattress helps maintain a perfect atmosphere by removing excess moisture and heat. It has five different pressure zones and provides 275 liters of air per minute. The features combination of Invacare true low air loss therapeutic support mattress helps to maintain reasonable skin temperature and moisture level.


How Does a Low Air Loss Mattress Help to Prevent Pressure Injuries

Low Air Loss Mattress Help to Prevent Pressure Injuries

What is pressure injury? It is a skin condition related to skin and underlying tissues generally caused by constant pressure. The prolonged pressure interrupts the blood and oxygen flow over the whole body. Pressure sores are also caused by shear, friction, pressure, and moisture, along with prolonged stress.

In that case, a low air loss mattress can effectively work to prevent pressure injuries. Basically, a low air loss mattress uses two different methods to avoid injuries of pressure; here they are:

  • Continuous Low Pressure: Continuous Low Pressure, also known as CLP, is a surface technology that immerses and envelopes the consumer. The air chambers will be distributed within the air bed by following the user’s movement. This action ensures lowered and comfortable contact pressures
  • Microclimate Management: A low air loss mattress uses a gentle airflow to offer a heat-moisture gradient under a vapor-permeable cover. This action keeps skin cool and dry and helps to maintain microclimate. It is a preferred method for low air loss patients who require active microclimate management

Who Can Benefit from a Low Air Loss Mattress?

Low air loss mattress is an innovative mattress that is useful for those who have pressure ulcers, ulcer symptoms, and immobility. It is particularly advantageous or beneficial for those who are suffering from immobile. Instability causes chronic stress on the shoulders, elbows, buttocks, and heels.

Chronic stress or pressure makes people unable to move on the bed, and it helps to develop pressure ulcers. Here are some others who will get benefit by using a low air loss mattress:

  • Paraplegic or Quadriplegic
  • Comatose
  • Hospitalized in Intensive Care
  • Recovering from Surgery
  • Terminally Ill

A low air loss mattress will aid in relieving stress from vital areas of your body and maintain a comfortable position. This mattress will also be useful for those who have proper blood supply issues. It’ll improve blood flow and keep your skin dry by providing airflow.


When Should a Loss Air Loss Mattress Be Used?

Since a low air loss mattress is used for prevention and treatment, it should be used for specific medical conditions. An air mattress is for those who have developing or severe pressure ulcers, bed-confined for a while, and who is-

  • Primarily bed-confined
  • Have symptoms or signs of evolving pressure ulcers
  • Who is suffering from an open stage or open pressure ulcer

Final Thoughts

A pressure mattress will ensure maximum patient comfort by reducing skin interface pressure. It helps speed recovery by improving oxygenation and blood flow. A low air loss mattress uses air work periodically by being attached with a series of air bubbles. The air bubbles inflated and deflated to prevent overexposure from pressing on the sore area. These actions are also very effective for reducing the amount of moisture build-up, which can make the sores worse.
