Immobile patients suffer from constant pressure on specific areas, resulting in ulcers that often cause pain and are difficult to heal. Pressure ulcers (or decubitus ulcers) are persistent and costly problems in hospitals, nursinghomes, and long-term care facilities. The mitigation strategy often involves constant rotation of patients, which uses the time and resources of care providers. Modulim’s SFDI technology can help clinicians monitor circulation changes that precede ulcers and allow caregivers to intervene proactively. If an ulcer has already formed, SFDI technology can help clinicians track and document the impact of treatment attempts. A recent publication demonstrated how SFDI was used as a tool for skin assessment in subjects at risk for pressure ulcers (Yafi et al. 2017).
