This document provides information and instructions for selecting measurement sites and preparing skin for tcpO2 monitoring using PeriFlux 6000. It recommends that physicians select sites and advises avoiding sharply curved anatomy, bony prominences, large vessels, calloused skin, heavy edema and infected areas. The steps for site preparation and electrode fixation are outlined, which include removing hair, blotting with tape until clean, wiping with alcohol, aligning and securing the electrode and fixation ring. Photos should be taken and sites marked or labeled. Example comments are provided for different clinical situations.

3. • Calibration
• tcpO2 Site Selection
• Electrode Maintenance
• Interpreting Curves and Results

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. 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. 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. Take a Photo and Indicate Sites
Mark sites
using handle

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. Electrode Fixation - Comments
But when it looks
like this…
…suspect electrode
leakage.
Check attachment of the
fixation ring!
