Choice Of Pressure Relief Cushions

By Maryanne Goff


Pressure relief cushions are an important tool for helping individuals required to sit in wheelchairs for long periods of time. They help to maintain the health of the skin by distributing pressure in a variety of ways. They also help give postural stability and prevent shear force.

Blood needs to circulate freely so that oxygen and nutrients can be delivered to the cells. When blood flow decreases, problems like ulcers can occur and areas like the buttocks and shoulders are particularly vulnerable. Ulcers can cause significant problems, resulting in a need for surgery at times. Shear force is a problem that occurs when the skin outer layer and the inner tissue are pulled apart. This can happen when a person slips down in the chair.

Each and every individual will have different requirements when it comes to choosing a cushion. A clinical professional will be able to assist with making the right choice. Specific factors such as how much time is spent in a chair, how much the user moves around, stability of posture and nature of a disability must all be taken into consideration.

The wheelchair and cushion must work together. There are many sizes and depth of cushions available. The correct one has to be chosen to ensure that when the individual is sitting on the cushion, the height is correct in relation to the armrests and the back of the chair.

Different materials such as gel, foam, air and water are used in these products. This is because they are able to conform to the shape of the body, distributing weight and allowing for optimum blood flow. They all have this in common but when it comes to cost, weight, heat conduction and stability there are different advantages and disadvantages.

A foam cushion is one of the least expensive options and it comes in a range of densities and varying degrees of memory. If the foam is cross cut, contoured or convoluted, it allows greater conformity so that the surface moves with the user. As it is relatively inexpensive and easy to cut, a therapist can experiment with shapes without incurring too much expense. On the downside it does wear down more quickly than other materials, losing its shape and becoming compressed.

Air filled cushions are comfortable and widely used. Those with pumps that allow rows of cells filled with air to inflate and deflate, thus alternating the point of pressure, are particularly effective. The main disadvantage is that an air cushion has to be checked regularly to make sure that it is properly inflated.

A gel cushion conforms well to body shape and movement, providing good weight distribution. It is also suitable for those who often feel hot and sweaty as it helps to keep the skin feeling cool. However, it is heavy in weight which makes it unsuitable for users who often have to be lifted in and out of the car or the wheelchair.

The cost of pressure relief cushions can vary considerably, according to the materials with which they are made, covers, size and depth. It is worthwhile to purchase a product with proven performance over time. This may not be the cheapest option but durability, comfort and effectiveness should take precedence over cost.
