When assessing a cushion, I always recommend looking at the method of pressure distribution, the geometry and the medium.

Methods of Pressure Redistribution
It’s easy to think that a skin protection cushion should be soft and cushy and cradle the skin. But in reality, it’s all about redistributing pressure over a larger surface area to decrease high peak pressures in just one area. There are different methods of pressure redistribution:

The best way to assess the geometry of a cushion is by feeling it. Not only sitting on it but taking the cover off and running your hand from side to side and front to back, feeling the contours. When it comes to Vicair cushions the cells will shift and move with your hand, but you will be able to see and feel the inherent contours of the cushion.

The medium of a cushion refers to what the cushion is made of. There are multiple options that manufacturers use and each has its benefits and considerations.

  • Foam
  • Air
  • Honeycomb
  • Gel/Fluid inserts
  • Combination

It’s important to remember the functional and postural goals of your client when considering the medium. Think of the weight of the cushion since each medium has different properties making them lighter or heavier. Each medium also has different qualities that affect the stability of the surface, which can affect the ease of transfers, pelvic posture, and sitting tolerance. How each medium (i.e. air, foam, etc) is used in the cushion, as well as the quality and design of the materials used, impact the interaction between the cushion and the user.


Now that we've gone over methods of pressure distribution, cushion geometry, and cushion medium, let’s look at the clinical application of the models of Vicair cushions:

Vicair Vector O2

Vector O2Method of pressure Distribution: Partial Offloading

Geometry: Contoured

Medium: Static Air through SmartCells

Clinical Indication: A lightweight high quality skin protection option with a soft end feel yet stable enough for slide board transfers. Contours with rear raised compartments load trochanters to provide pelvic stability. The contours are adjustable by adding/removing SmartCells to accommodate or correct for postural asymmetries.


Vicair Adjuster O2

Adjuster O2Method of Pressure Distribution: Immersion

Geometry: Linear

Medium: Static Air through SmartCells

Clinical Indication: A lightweight high quality skin protection option with a soft end feel yet stable enough for slide board transfers. The linear style can accommodate all body types and postural asymmetries.


Vicair Active O2

Active_O2Method of Pressure Distribution: Partial Offloading

Geometry: Contoured

Medium: Combination of SmartCells in the rear and foam in the front

Clinical Indication: A high quality skin protection option with cells in the rear and foam in the front making it stable for slide board transfers, and for pushing up during transfers. Contours in the lateral rear compartments load the trochanters, offering pelvic stability.


Infection Control and Hygiene

These days infection control and hygiene have never been more relevant and important. An important feature for all Vicair cushions is that they are *machine washable with the cells remaining in the compartments. I recommend removing the cover, zip tying the zippers to keep the cells in and putting the cushion in the washing machine. This is an easy way to maintain the cleanliness of the cushion and controlling the possible threat of infection.

*Covers must be removed and washed according to instructions. In Vicair Active O2, the foam must be removed from the liner before placing in washing machine.
