Transcutaneous Oximetry
1) Regional Perfusion Index (chest 02 level/ 02 at level in
question)
a. Probable Healing 0.60-1.00
b. Questionable Healing 0.40-0.60
c. Healing Not Probable 0.00-0.40
Venous Duplex Upper and Lower Extremity
1)
Doppler Signals (present, continuous, reduced,
pulsatile, absent)
a.
Spontaneous - signal clearly heard
b. Phasic - flow increases with expiration and decreases
with inspiration
c. Augmentation - increase in signal
with distal
compression
d. Competency - signal cessation with
proximal
compression
e. Patency
2)
Vessel Compressibility
a.
Fully Compressible
b.
Partially Compressible
c. Non-compressible
3) Disease Stages
a. Acute
Thrombosis
1. Vessel is
non-compressible
2. Vessel
dilatation
3. Thrombus
may be visible in vessel lumen
4. Abnormal
Doppler signals
5. Absent or partial filling of the vessel lumen with
Color
Doppler
b.
Sub Acute Thrombosis
c. Chronic Thrombosis
1. Highly echogenic clot
2. Visible collateralization or recanalization
(vessel compresses and linear,
echogenic intraluminal striations present)
3. Vessel is not dilated
4. Abnormal Doppler signals may be present
