The formation and underlying causes of pressure ulcers (PUs) are quite complex,
with multiple influencing factors. However, by definition pressure ulcers cannot
form without loading, or pressure, on tissue. Clinical interventions typically
target the magnitude and/or duration of loading. Pressure magnitude is managed by
the selection of support surfaces and postural supports as well as body posture
on supporting surfaces.
Duration is addressed via turning and weight shifting
frequency as well as with the use of dynamic surfaces that actively redistribute
pressure on the body surfaces. This article shows that preventative interventions
must be targeted to both magnitude and duration and addresses the rationale
behind several common clinical interventions--some with more scientific evidence than others.
