Treat Raised SEM Deltas (Δ) to prevent
broken skin PI/U and DTIs

The Status Quo

logo circles

PUs are frequent, serious and expensive wounds1,2,3,4

logo circles

PUs occur in hospital, hospice and community settings

logo circles

Risk assessments are subjective and not anatomy specific5

logo circles

Current standard of care (visual and tactile skin assessments) cannot detect pre ulceration skin changes which can then progress to more severe broken skin PUs

logo circles

Skin assessments only trigger interventions after skin redness is visible

logo circles

Current standard of care fails patients with dark skin tone, as redness is not visible6

Changing The Status Quo

Electrical property of tissue; a biophysical measure of changes in localized oedema also known as sub-epidermal moisture (SEM)

logo circles

Tissue biocapacitance increases when SEM increases

As a result of a localized inflammatory response triggered due to a developing PU; this is non-visible tissue damage7

SEM is one of the earliest indicators of a developing PU that is still microscopic

Concept of SEM is now proven in the published literature:

  • SEM can now be accurately measured via the Provizio® SEM Scanner8,9
  • Raised SEM is proven to indicate microscopic pre ulcer skin changes
  • Raised SEM should be regarded as a condition that should be treated
  • Treat a raised SEM delta as per a stage one PU
  • Monitor the impact of your treatment actions ……and review the care plan
