Choosing a low-air loss antidecubitus mattress

A low-air loss mattress is an effective tool against bedsores (pressure sores). However, there are numerous options you have to make the right choice. When do you choose a low-air-loss mattress and what are its benefits? You’ll read about it below!

What is a low air loss antidecubitus mattress?

A low-air loss mattress, as the name suggests, releases very little air. A low-air loss mattress is filled with air cells, which are inflated by an electric pump. The cells contain small holes, through which the air escapes. However, the holes are so small that the air cannot disappear quickly. Hence the “low air loss”.

The pump automatically turns on when needed. The air cells are supplied with new air when they have let too much through. From that point, the process begins again: the full air cells slowly release air until a certain level is reached and new air is added.

When do you use a low-air loss antidecubitus mattress?

You can use a low-air loss mattress at various times. The purpose of such a mattress is mainly the prevention of bedsores. It is therefore often used as a prevention tool.

Constant airflow around the body

A low-air loss antidecubitus provides a constant flow of air around the body of the person lying on the mattress. The air that slowly exits the cells continually supplies the sleeper’s body with fresh air. The new and fresh air keeps the skin in better condition. The better condition of the skin comes from effectively combating two phenomena:


The air currents counteract maceration. Maceration is softening of the skin and can also be called fluid injury.


Blemish spots are also prevented by airflow. A blemish spot is eczema that occurs when skin is exposed to heat, moisture and friction.

Preventing maceration and blemishes reduces the risk of bedsores.

Option: alternating action
The low-air loss mattress from Bos Medical International also has the option of alternating action. Alternating mattressesalternate the pressure so that not one area is constantly stressed. The alternating pressure reduces the risk of pressure sores and also helps in the healing of pressure sores. For more information, ask for a quote.

Here’s what to look out for when using a low-air loss mattress

When deploying a low-air loss mattress, you do need to pay attention to a few things.

  • The thickness of a fitted sheetcan influence the effect of air flow. You want to minimize this, so preferably use thin materials for over the mattress.
  • The need for alternate lying must also be considered when using a low-air loss mattress. Seek professional medical advice to determine if alternate lying is necessary. In general, alternate lying is not necessary when the patient (at high risk without pressure sores) does not exceed 90 kilograms in weight.
