About Therapeutic Support Surfaces (TSS)

In the United States, medical mattresses are classified into four different groups based on their intended use and the level of support they provide. Group I medical mattresses are designed for use in low- to moderate-risk pressure ulcer prevention and treatment. Group II medical mattresses are designed for use in moderate- to high-risk pressure ulcer prevention and treatment.

One key difference between Group I and Group II medical mattresses is the level of support they provide. Group I medical mattresses are typically less supportive and are intended for use in patients with a low risk of developing pressure ulcers. Group II medical mattresses, on the other hand, are more supportive and are intended for use in patients with a moderate to high risk of developing pressure ulcers.

Another difference between the two types of mattresses is the level of immersion or contouring they provide. Group I medical mattresses tend to have less immersion or contouring, while Group II medical mattresses may have more immersion or contouring to help reduce pressure on the skin.

Both Group I and Group II medical mattresses are designed to help prevent and treat pressure ulcers, but they are intended for use in different patient populations and may have different features and levels of support. It's important to choose the appropriate medical mattress based on the needs and risk level of the patient.

Bed sores / pressure ulcers occur when there is prolonged pressure on a certain area of the skin. This pressure can cause damage to the skin and underlying tissues, leading to the development of an ulcer.

Here are three top reasons people get bed sores:

1. Immobility: When a person is unable to change positions or move around, such as due to a medical condition or disability, they are at risk of developing bed sores. This is because the constant pressure on one area of the body can cause the skin and tissues to break down and lead to the formation of an ulcer.
2. Friction and Shear: Friction occurs when the skin is rubbed against a surface, such as when a person slides down in a chair or bed. Shear occurs when the skin is pulled in one direction while the body slides in another direction, which can also damage the skin and tissues. Both friction and shear can contribute to the development of bed sores.
3. Moisture: Prolonged exposure to moisture, such as from sweating or incontinence, can also increase the risk of bed sores. Moisture can soften the skin and make it more susceptible to damage from pressure, friction, and shear.

It's important to note that other factors can also contribute to the development of bed sores, including poor nutrition, reduced blood flow to the skin, and certain medical conditions. If you or someone you know is at risk of developing bed sores, it's important to take steps to prevent them, such as changing positions regularly, using special cushions or mattresses, and keeping the skin clean and dry.
