The purpose of this clinical study is to correlate tissue oxygenation values measured with a hyperspectral imaging system (OxyVu) to Ankle Brachial Indices (ABI), toe pressures (TBP), and transcutaneous oxygen monitoring (TCOM) in patients scheduled for foot level amputation because of critical limb ischemia, infection, or tissue necrosis.
Correlation of(OxyVu) values to to ABI, TBP, and TCOM in patients scheduled for foot level amputation because of critical limb ischemia, infection, or tissue necrosis.
