How Does A Pressure Mattress Work
Pressure mattresses are designed for those with pressure ulcers . Pressure sores occur when an individual spends prolonged periods of time in the same position and typically occurs in those with restricted mobility and/or poor skin integrity. It is crucial to get the right type of pressure mattress for the right grade of bed sore in order to maximise patient comfort.
This blog will explain what a pressure mattress is and how it differs from a regular mattress. It will also show how a pressure sore mattress works and how they are effective for increasing comfort for those suffering from bed sores.

Availability Of Any Information On Pis
In total, our search yielded 23 sources of PI patient education materials, including brochures, leaflets, static websites , pamphlets, and a video clip .1). Figure Figure11 shows the availability of patient education materials in relation to hospital funding and location. The results show more than half of the hospital websites accessed did not contain any information for patients on prevention and management of PIs, indicating that only 71 of the 212 hospitals had these materials. Private hospitals were more likely to have patient information about PIs on their website than public hospitals . A chisquare test showed that there was a statistically significant association between the hospital type and the likelihood of having PI material on their website, 2 = 26.31, P< .001. Similarly, metropolitan hospitals were more likely to have PI materials on their websites compared to rural hospitals , and the association between the location type and PI educational material availability was statistically significant 2 = 24.37, P< .001.
Description Of The Intervention
The aim of pressure ulcer prevention strategies is to reduce either the magnitude, or duration, of pressure between a patient and his support surface , or both. This may be achieved by regular manual repositioning , or by using pressurerelieving support surfaces such as cushions, mattress overlays, replacement mattresses or whole bed replacements, which are widely used in both institutional and noninstitutional settings. Often a combination of repositioning and support surface enhancement may be used. Support surfaces are used with the aim of redistributing pressure, reducing shearing forces and controlling the local microclimate. The cost of these interventions varies widely from over GBP 30,000 for some bed replacements, to less than GBP 100 for some foam overlays. Information on the relative costeffectiveness of this equipment is needed to inform use.

Outcomes And Data Collection
The MICU nurses assessed patients skin at unit admission and every shift as standard practice and documented their assessment in the electronic medical record that was date and time-stamped. Certified wound ostomy continence nurses were available for consultation if nurses were unsure how to stage or describe a wound. Pressure injuries were documented using the National Pressure Injury Advisory Panels staging classification system . Hospital protocol required clinical nurses to document all stages of pressure injuries in the EMR. The WOC nurse was consulted for all HAPI and higher stage pressure injuries that were present at admission. In cases in which WOC nurse had documented wound staging, their assessment was used in place of the documented stage entered by clinical nurses. Only UAPIs that were on body surfaces in regular contact with bed linens were abstracted from the EMR, thus excluding UAPIs caused by tubing, devices, dressings, and drains. Data were only collected on UAPI, not preexisting pressure injuries. Trained research nurses examined every patient every day for the first 6 months of the trial to ensure that clinical nurses were accurately describing wounds in the EMR and to ensure consults to wound care nurses were requested when needed. Data were abstracted from the EMR after patients were discharged.
Prevention Of Heel Pressure Ulcers In An Orthopaedic Unit
18 June, 2002
VOL: 98, ISSUE: 25, PAGE NO: 53
Anne Wilson, RGN, BSc, is tissue viability nurse, Royal Alexandra Hospital, Paisley
The development of hospital-acquired pressure ulcers on the heel is a well-acknowledged problem . In fact, after the sacrum the heels are the second most common anatomical site for the development of ulcers , and their incidence has increased steadily over the past few decades .
Although tissue breakdown is a complex multifactorial process, the focus with pressure ulcer development in the heels is on extrinsic factors such as pressure, shear and friction, with the most plausible explanation being the failure to relieve pressure. While many advances, such as pressure-relieving mattresses and beds, have greatly reduced the incidence of sacral ulcers . Krasner recognised that, even with pressure reduction, most support surfaces do not adequately relieve heel pressure.
Pressure ulcers may form when heel pressure on the mattress exceeds the capillary closing pressure and the heel position is not changed frequently enough . The heel is at increased risk of ulceration as it has a relatively low resting blood perfusion level if subjected to lower pressures than 32mmHg .
Cheney suggests this problem is compounded by orthopaedic surgical procedures requiring long periods in the operating room and in recuperation. To prevent the development of heel ulcers, therefore, predisposing factors must be identified, minimised and/or relieved .

How Pressure Ulcers Develop
Pressure ulcers can develop when a large amount of pressure is applied to an area of skin over a short period of time. They can also occur when less pressure is applied over a longer period of time.
The extra pressure disrupts the flow of blood through the skin. Without a blood supply, the affected skin becomes starved of oxygen and nutrients, and begins to break down, leading to an ulcer forming.
Pressure ulcers tend to affect people with health conditions that make it difficult to move, especially those confined to lying in a bed or sitting for prolonged periods of time.
Conditions that affect the flow of blood through the body, such as type 2 diabetes, can also make a person more vulnerable to pressure ulcers.

Can Using A Waterbed And An Air Mattress Together Relief Pressure Ulcers
While there is limited data showing how a waterbed could be used to treat pressure ulcers, there are a few studies which have shown correlations in recovery and care. A waterbedâs delicate nature, as well as revolving air pressure in an air mattress, could provide significant relief to individuals suffering from bed sores.
If youre thinking about employing a waterbed to treat or help care for a loved one, consult your doctor to discuss the best strategy of care.

Risk Factors For Pressure Sores
A pressure sore is caused by constant pressure applied to the skin over a period of time. The skin of older people tends to be thinner and more delicate, which means an older person has an increased risk of developing a pressure sore during a prolonged stay in bed.
Other risk factors for pressure sores include:
- immobility and paralysis for example due to a stroke or a severe head injury
- being restricted to either sitting or lying down
- impaired sensation or impaired ability to respond to pain or discomfort. For example, people with diabetes who experience nerve damage are at increased risk of pressure sores
- urinary and faecal incontinence skin exposed to urine or faeces is more susceptible to irritation and damage
- malnutrition can lead to skin thinning and poor blood supply, meaning that skin is more fragile
- obesity being overweight in combination with, for example, immobility or being restricted to sitting or lying down can place extra pressure on capillaries. This then reduces blood flow to the skin
- circulation disorders leading to reduced blood flow to the skin in some areas
- smoking reduces blood flow to the skin and, in combination with reduced mobility, can lead to pressure sores. The healing of pressure sores is also a slower process for people who smoke.
If youre bedridden, pressure sores can occur in a number of areas, including:
- back or sides of the head
- rims of the ears
A person is at risk for pressure ulcers if s/he
How Do Air Mattresses For Hospital Bed Work
As mentioned above, the air cylinders in the alternating pressure mattresses are placed parallel to each other. The air moves in a sequence from one cylinder to another to perfuse the blood in areas which are at higher risk of developing pressure ulcers. When one cell gets inflated, the other one gets deflated. This motion of air within the pneumatic mattress relieves the pressure on problematic areas of the body regularly, stimulating blood flow.

Which Interventions Are The Most Important
Pressure ulcers usually heal very slowly, and may come back. Thats why its so important to make sure they dont develop in the first place. People who are confined to a wheelchair or have to stay in bed for a long time often say that they can feel parts of their body becoming sore. Its important to pay attention to what they say, to quickly reduce pressure on their skin, and regularly change the position they sit or lie in.
Observing which parts of the body are most susceptible to pressure, as well as the positions that put the most pressure on them, can help you get an idea of what sort of relief might be helpful. For example, lying down puts much less pressure on your backside than sitting in a chair. If you use a wheelchair, you can find out what helps to reduce the pressure and then make that your routine.
Its also important to try to move if possible even if you have to lie in bed or sit in a wheelchair. If you are able to sit up, leave the bed, or even walk a few steps with a bit of help, its a good idea to do that as often as possible.
When You Are In Bed
Use a foam mattress or one that is filled with gel or air. Place pads under your bottom to absorb wetness to help keep your skin dry.
Use a soft pillow or a piece of soft foam between parts of your body that press against each other or against your mattress.
When you are lying on your side, put a pillow or foam between your knees and ankles.
When you are lying on your back, put a pillow or foam:
- Under your heels. Or, place a pillow under your calves to lift up your heels, another way to relieve pressure on your heels.
- Under your tailbone area.
- Under your shoulders and shoulder blades.
- Under your elbows.
Other tips are:
- DO NOT put pillows under your knees. It puts pressure on your heels.
- Never drag yourself to change your position or get in or out of bed. Dragging causes skin breakdown. Get help if you need moving in bed or getting in or out of bed.
- If someone else moves you, they should lift you or use a draw sheet to move you.
- Change your position every 1 to 2 hours to keep the pressure off any one spot.
- Sheets and clothing should be dry and smooth, with no wrinkles.
- Remove any objects such as pins, pencils or pens, or coins from your bed.
- DO NOT raise the head of your bed to more than a 30 degree angle. Being flatter keeps your body from sliding down. Sliding may harm your skin.
- Check your skin often for any areas of skin breakdown.

Characteristics Of The Skin Model
The hardness of the skin model was tested using a durometer . We used the disk-shaped polyurethane resin without a cavity as a specimen for the hardness test . The data were compared with those reported in previous studies on human skin.23
To test the skin models smoothness, a friction tester was used. The rectangular-shaped polyurethane resin sheet without a cavity was used for the specimens for the smoothness test . According to a previous report,24 the friction force was measured against polytetrafluoroethylene by covering the probe of the tester with a PTFE sheet. The tests were conducted at a contact pressure of 4 kPa, liner sliding velocity of 100 mm/s, and sliding stroke of 80 mm.

How Can A Mattress Help In Pressure Ulcer Prevention
A mattress can help prevent bedsores from appearing by evenly distributing the weight so that no one spot receives an overly concentrated amount of pressure. This is often challenging with individuals who are bedridden or immobile, however, frequent adjustments are critical for prevention.
Various types of mattresses work well for preventing these ulcers.
Air loss cushions work by simulating a weightless sensation, relieving pressure from the afflicted area. Dynamic beds work by inflating bubble cells for support and deflating ones near the infected region for relief.
Static mattress work by using modern foams to distribute weight and reduce the chance of bedsores and prolonged tension. Finally, hybrid mattresses are a combination of a static and a dynamic mattress, using features beneficial to both designs, and work well for high-risk individuals.
Causes And Prevention Of Pressure Sores
Pressure sores are wounds that develop when constant pressure or friction on one area of the body damages the skin. Constant pressure on an area of skin stops blood flowing normally, so the cells die and the skin breaks down.
Other names for pressure sores are bedsores, pressure ulcers and decubitus ulcers.

How The Intervention Might Work
Pressurerelieving cushions, beds and mattresses either mould around the shape of the patient to distribute the patient’s weight over a larger contact area devices) or vary the pressure beneath the patient mechanically, thus reducing the duration of the applied pressure devices) . CLP devices can be grouped according to their construction . These devices fit, or mould, around the body so that the pressure is dispersed over a large area, and are mainly classified as being of a lower technological specification . By comparison, airfluidised beds, where warmed air circulates through fine ceramic beads covered by a permeable sheet, and lowairloss beds, where patients are supported on a series of air sacs through which warmed air passes, are highspecification CLP devices.
Alternatingpressure devices generate alternating high and low interface pressures between body and support, usually by alternate inflation and deflation of airfilled cells. Such devices are available as cushions, mattress overlays, and singleor multilayer mattress replacements. These devices are classified as “hightech”.
Other support surfaces, such as turning beds, turning frames, net beds, and turning/tilting beds move patients who are unable to turn themselves manually or automatically. Pressure ulcer prevention is often not the reason for using turning and tilting beds, which may be used in Intensive and Critical Care Units for other reasons, e.g. to promote chest drainage.
Use Pillows Cushions Or Special Mattresses
Using pillows or cushions as soft buffers between your skin and the bed or chair can be helpful. No two skin surfaces should rest against each other, eg, while lying in bed, place a pillow between your knees and ankles to prevent them from touching each other. If you are confined to bed, ask your healthcare provider about the use of heel and knee protectors or pressure relieving mattresses.
