Introduction
KEY AREAS IN THE TREATMENT OF COMPROMISED SKIN
Pressure Relief
The Arise® is divided into three distinct anatomical zones: head, seat, and foot. Each zone is adjusted to ensure optimal
pressure relief and provide a comfortable sleeping surface.
Maximum pressure relief is achieved through delivering a specific amount of air to each therapy cell and allowing
controlled amounts of air to escape, thus equalizing the pressure between the patient and the therapy cells. This
distributes the patient’s weight evenly over a wide surface area resulting in average pressure readings below capillary
closure levels.
Moisture Control
Patients are at risk for skin maceration if excess moisture is permitted to accumulate beneath the patient. This may be
due to perspiration, incontinence or wound drainage.
On the Stryker AIr I and II mattress system, moisture is controlled via the specially treated breathable, fluid-proof, urethane
coated nylon therapy pad. The moisture vapor permeable fabric of the therapy pad allows a sufficient amount of air to
circulate beneath the pad and wicks away excess moisture.
Shear and Friction Reduction
Shearing occurs when the skin is stationary in relation to the support surface, while the underlying tissues and vessels
are stretched and damaged. When a patient’s skin rubs against another surface, the result is friction. The top surface of
the Stryker AIr I and II mattress system therapy pad is constructed from a very smooth nylon fabric with low friction and
shear properties to protect the patient’s skin from these damaging forces.
