  3. 3. • Calibration • tcpO2 Site Selection • Electrode Maintenance • Interpreting Curves and Results
  4. 4. Site Selection • Physician should be selecting sites • Avoid the following: – Sharply curved anatomy – Bony prominences – Large superficial vessels – Plantar surface of the foot – Calloused skin – Heavy edema – Infected and inflamed areas
  5. 5. Site Preparation 1. Remove hair from area (if necessary) 2. Blot with medical tape Change tape and repeat until tape appears ”clean” 3. Wipe with alcohol Clean site carefully before attaching of fixation rings!
  6. 6. Electrode Fixation 4. Align electrode arrow with tab 6. Secure cable with tape 5. ¼ turn clockwise align arrow with line 2. Attach fixation ring and adhere firmly 3. Four drops of contact liquid 1. Choose TC 550 (normal) or TC 555 Extra Strength Adhesive
  7. 7. Take a Photo and Indicate Sites Mark sites using handle Name channels Tap and browse to photo or choose image
  8. 8. Site Selection - Comments Fixation ring Wound Example Comment Patient without a wound Preferably place electrodes as distal as possible (for example close to the big toe). tcpO2 will provide a general measure of the microcirculatory status at the measuring site. This is particularly useful in patients with diabetes and CLI in addition to macrovascular tests such as ABI and toe pressure. Patient with a wound Place electrodes surrounding the wound, both distal and proximal. A mean of several tcpO2 values is a better predictor of wound healing potential than single site values. Amputation level selection Place electrodes at different suggested levels to be able to decide the optimal amputation level. Reference site Place an electrode on the contralateral side as a reference/control. If possible, rule out arterial hypoxemia with pulse oximetry. CLI = Critical Limb Ischemia
  9. 9. Electrode Fixation - Comments But when it looks like this… …suspect electrode leakage. Check attachment of the fixation ring! Typical data
