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.
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.

| Measure | Description | Time Frame |
|---|---|---|
| Assess predictive value for healing by 8 weeks of OxyVu, ABI, TBI and TCOM measured prior to amputation. OxyVu readings for oxyhemoglobin, deoxyhemoglobin and oxygen saturation will be compared to healing potential predicted from ABI, TBI, and TCOM. | 8 weeks |
