Accuracy of TCOM vs NIRS in Predicting Wound Outcomes in Patients Treated With or Without Revascularization

Purpose

The primary purpose of this project is to compare the accuracy of transcutaneous oxygen monitoring and near infrared spectroscopy in assessing cutaneous oxygen levels in chronic wounds of patients following revascularization procedures as well as those with conservatively managed chronic wounds. This study will also compare the efficiency and practicality of both methods in guiding treatment decisions and management of these wounds.

Arm Groups

ArmDescriptionAssigned Intervention
Revascularization This group will include patients whose cutaneous oxygen partial pressure (PO2) around the wound of interest measures less than 40 mmHg and therefore require revascularization.
  • Diagnostic Test: Near Infrared Spectroscopy
    The Kent Camera is intended for use by healthcare professionals as a non-invasive tissue oxygenation measurement system that reports an approximate value of the following in superficial tissue: oxygen saturation (StO2), relative oxyhemoglobin level (HbO2), and relative deoxyhemoglobin (Hb) level The Kent Camera displays two-dimensional color-coded images of tissue oxygenation of the scanned surface and reports multispectral tissue oxygenation measurements for selected tissue regions. The Kent Camera is indicated for use to determine oxygenation levels in superficial tissues.
Medical Management This group will include patients whose cutaneous PO2 around the wound of interest measures greater than 40 mmHg and will be managed conservatively in wound clinic
