Pressure Injury Prevention
Sub-Epidermal Moisture (SEM)
Deliver objective and anatomically-specific assessment of pressure injury (PI) risk 5 days*¹ earlier than visual skin assessment, regardless of skin tone². This empowers you with a window of opportunity to deploy a tailored prevention strategy to minimize PI incidence.

The Science of Sub-epidermal Moisture (SEM)
Elevated levels of SEM is a biomarker of early tissue damage that can lead to pressure injury development. SEM can be identified by assessing the biocapacitance of tissue. This non-invasive technology enables early and objective assessment of increased pressure injury (PI) risk, empowering you to take decisive action to minimize PI incidence and to help reduce overall cost and time to care.
