Ischaemic Ulcer

Wound healing is influenced by numerous factors including blood flow, tissue oxygenation and vascular pressures (such as toe pressure). Insufficient levels of these factors can delay the wound healing process. Non-healing chronic wounds and ulcers (including diabetic foot ulcers, ischaemic ulcers and pressure sores) are a highly significant factor in healthcare cost in addition to patient suffering and in extreme cases limb amputations and even mortality. Moor Instruments provides a range of equipment enabling simple, rapid and non-invasive monitoring of blood flow, tissue oxygen saturation and temperature. Low profile probes are available for use under dressings. In addition should you wish to image blood flow of the microcirculation over the exposed wound surface we have a range of non-contact, non-invasive, rapid imaging systems available.

Equipment Recommendations

To image the blood flow over the surface of the wound and provide a blood flow map we recommend the moorFLPI-2 imager.

Should you wish to simultaneously measure blood flow, tissue oxygen saturation (SO2) and temperature we recommend the moorVMS-OXY system, moorVMS-LDF, probes and moorVMS-VASC PC software. The moorVMS-PRES will add pressure cuff assessments.
