SEM Delta™ (∆)

May 5, 2026

SEM Delta (∆) is a simple way of identifying where pressure injury risk is developing beneath the skin before it becomes visible. It helps clinicians move from guessing risk across the whole body to identifying specific areas that need attention now. A Quick Recap: What Is SEM? Sub-epidermal moisture (SEM) is the build-up of fluid…

Pressure Injury Prevention Technology: A Clinical Guide to What Works, What’s Cleared, and What to Ask

Wed, May 20, 1:00 PM - 1:30 PM EDT

Not all pressure injury prevention technologies are equal — and the marketing claims make it hard to tell the difference. From SEM measurement to thermography to near-infrared spectroscopy to motion sensors, the landscape is crowded, the regulatory nuances matter, and the clinical evidence varies widely. Making the wrong call has real consequences for patients and…

Introduction to Biocapacitance

May 4, 2026

Biocapacitance is a method of measuring how much fluid is present in tissue beneath the skin. It is based on a simple idea: the more fluid in the tissue, the more its electrical properties change. What Is Biocapacitance? Biocapacitance is an electrical property of tissue that varies depending on how much moisture it contains. Low…

SEM Assessment: Detection, Treatment and Prevention

May 3, 2026

Pressure injuries often begin below the surface of the skin before they can be seen. Sub-epidermal moisture, or SEM, is one of the earliest measurable signs that tissue damage may be developing. SEM assessment helps clinicians detect early tissue changes, act sooner, and monitor whether prevention efforts are working. What Is SEM? SEM stands for…

Pressure Injury Classifications

May 3, 2026

Pressure injuries are classified (or staged) by how much tissue damage is visible. These classifications help clinicians describe the severity of an injury, guide treatment, and track whether the wound is improving or getting worse. The internationally adopted system includes six main classifications: Stage 1, Stage 2, Stage 3, Stage 4, Deep Tissue Pressure Injury,…

Introduction to Pressure Injuries

May 3, 2026

A pressure injury (also known as a bed sore or pressure ulcer) is damage to the skin and the tissue underneath it, caused by prolonged pressure or pressure combined with shear (such as sliding in a bed or chair). They most often develop over bony areas of the body, like the heels and tailbone, but…

Using Rapid Tests of Change Accelerate the Path to Zero Pressure Injuries

April 23, 2026

For many clinical teams, the challenge in pressure injury prevention is not knowing what to do. It is knowing how to implement change quickly, consistently, and in a way that actually delivers outcomes. That is the focus of our latest webinar, “Using Rapid Tests of Change to Accelerate Your Path to Zero Pressure Injuries,” featuring…
