Abstract

This report outlines results from an independent study assessing the clinical potential of an emerging, contemporary imaging technology. Tissue Viability (TiVi) imaging is an easily implemented, non-invasive, and portable technique which maps the blood circulation in the surface dermal layer. However, its routine clinical implementation awaits the development of the necessary standardised protocols. Thus the pilot study examines the efficacy of a novel TiVi imaging device within a localised skin blood flow occlusion protocol. The test was administered to the upper volar forearm of 19 healthy subjects (10:9 Female:Male) for 5 different time periods ranging from 5 to 25 seconds. Dermal areas corresponding to 100 × 100 pixels (2.89 cm²) were monitored for 60 seconds prior to, during and after each occlusal test. Our results support the relevance of a TiVi occlusion protocol for physiological assessment of the skin microcirculation.
