Stages of Pressure Ulcers

Pressure ulcers can be graded from Stage
I to Stage IV to classify the degree of
tissue damage. Pressure ulcers do not
necessarily progress from Stage I to
Stage IV or heal from Stage IV to Stage I.

Stage I: _________________________

Non-blanchable erythema of intact skin,

the heralding lesion of skin ulceration.

In individuals with darker skin,

discoloration of the skin, warmth,

edema, induration, or hardness may

also be indicators.

Stage II: ________________________

Partial thickness skin loss involving

epidermis, dermis, or both.

Stage III: ________________________

Full thickness skin loss involving

damage to or necrosis of subcutaneous

tissue that may extend down to, but not

through, underlying fascia. The ulcer

presents clinically as a deep crater

with or without undermining adjacent

tissue.

Stage IV: ________________________

Full thickness skin loss with extensive

destruction, tissue necrosis, or damage

to muscle, bone, or supporting structures

(e.g., tendon or joint capsule).

Therapeutic Support Surfaces

Therapeutic Support Surfaces prevent and treat pressure ulcers by molding to the body
to maximize contact, redistributing weight as uniformly as possible, and reducing
pressure to below capillary closure (32mm/Hg).

While a variety of support surfaces

have been shown to improve pressure ulcers, there is no compelling evidence that
one support surface consistently performs better than all others, under all circumstances.
The primary concern when choosing a support surface should be the therapeutic benefit
associated with the product.

Invacare’s TSS line consists of Group I and Group II surfaces as defined by CMS. Each
Group can further be categorized by the type of surface and whether it is

dynamic

static.

Group I - Support surfaces designed to prevent pressure ulcers

• Gel Overlay –

Uniformly distributes pressure and reduces friction and shear with gel

bladders inside a foam core. Designed to be placed directly on top of an existing
mattress.

• Foam Mattress –

Multiple layers of foam for maximum pressure reduction. Designed

to be placed directly on the existing bed frame.

• Alternating Pressure Pad –

Alternates inflation and deflation of cells to constantly

change pressure points. Designed to be placed directly on top of an existing mattress.

Group II - Support surfaces designed to prevent and treat pressure ulcers

• Non Powered Pressure Reducing Mattress –

Channels air through cells for

maximum patient immersion.

• Alternating Pressure Mattress –

Alternates inflation and deflation of cells to

constantly change pressure points and promote circulation.

• Low Air Loss Mattress –

Floats the patient on air-filled cells while circulating air

across the skin to reduce moisture and help maintain a constant skin interface
pressure. “True Low Air Loss” utilizes 100-150 liters of air per minute to maintain
normal skin temperature and moisture levels, yet will not dry out therapeutic dressings.

• Lateral Rotation Mattress –

Gently rotates the patient from side to side to cyclically

change pressure points. Reduces risk of pulmonary complications, stimulates gastro-
intestinal tract, improves circulation and provides pressure relief without disturbing
the patient.
