Pressure injuries (PI) result from pressure-induced damage to the skin and underlying tissues.Currently, Stage I PI are detected using visual skin assessments.However, this visual method is unable to detect skin color changes in persons with darkly pigmented skin, which results in Cockatil Shaker a higher Stage II-IV PI incidence and PI-associated mortality in persons with a darker complexion.Thus, a more objective method of early-stage PI detection is of great importance.

Optical spectroscopy is a promising modality for the noncontact diagnosis and monitoring of skin water content, capable of detecting edema and Stage I PI.The scope of the current study is to assess the feasibility of imaging the water content of the skin using Si-based sensors.We have considered two primary cases: the elevated bulk water content (edema) and localized water pool (e.g.

, blood vessels).These two cases were analyzed using analytical models.We found that detecting the watercontent contrast associated with edema in tissues is within the reach of Si-based sensors.However, although the B6 effect is expected to be detectable even with consumer-grade cameras, with the current state of technologies, their use in real-world conditions faces numerous technical challenges, mainly due to the narrow dynamic range.
