Orthopaedic Seat Cushion for Patients for Pressure Ulcer Prevention

Orthopaedic Seat Cushion

Pressure ulcers are skin breakdowns caused primarily by excessive applied pressure. Heat, moisture, friction, poor nutrition, vascular problems, and inability of a person to move are also contributing factors to this, among many others.

Presence of these ulcers already has a significant negative impact on an individual and failure to provide protection to the skin for these not to occur, imposes more complications and risks.

Prevention of pressure ulcers is a vital measure, and this includes proper hygiene, pressure relief, proper skin inspection, and provision of appropriate seating surfaces.

For seating surfaces or seat cushions, they are chosen based on the medium and properties of the materials used in their construction: foam, air, gel, or combination types.

They vary in efficacy based on pressure distribution, provision of stability, ability to insulate, or conduct heat, and the reliability of their performance over time (Frontera & DeLisa, 2010).

Seat cushions are preferably prescribed and designed specific to the medical and functional needs of an individual and should promote improved positioning, pressure relief, and comfort.

Questions to Consider in Choosing Seat Cushions

  • Does the seat provide adequate support to promote good sitting posture?
  • Will the pressure distribution of the seat prevent pressure sores?
  • Is the shape of the seat cushion appropriate for the user’s body contours?
  • Does the person need a custom-shape to accommodate deformities and maximise support?
  • Are special combinations of foam, air, or gel seat cushions needed to maximise comfort and pressure relief?
