|
Basal State
|
A steady state in metabolism of systemic blood pressure |
|
|
Palpation
|
a method of feeling pulses with the fingers or hands during a physical exam |
|
|
segmental pressures
|
blood pressures obtained from cuffs places around the ankles calves and thighs |
|
|
pseudo-claudication
|
pain when walking that mimics vascular claudication, but is due to some other cause |
|
|
infrainguinal
|
below the groin crease |
|
|
Toe Pressures
|
useful in evaluating small vessel disease and in diabetic patients with calcified incompressible large vessels digital cuff on the great toe and PPG transducer positioned distally on the toe |
|
|
Subclavian Stenosis/ Occlusion |
When a gradient of 20mmhg or more between brachial pressures, on the side of the lower pressure |
|
|
Volume Plethysmography
|
the measurement of a volume change in a limb or organ |
|
|
Pluse Volume Recording PVR
|
Limb volume changes with systole, air is displaced within a cuff, instantaneous pressure change is recorded |
|
|
Normal PVR waveform
|
has a sharp upslope and a prominent reflected wave also called the dicrotic notch in late systole and early diastole |
|
|
PVR mild disease
|
waveform to broaden and the reflected wave will not be present there is also a slight loss of amplitude |
|
|
moderately abnormal PVR
|
has a rounded peak no reflected wavfe and a pronounced decrease in amplitude |
|
|
severely abnormal PVR
|
low amplitude or even flatline |
|
|
PVR ADVANTAGES
|
easy test, asses limb perfusion, not affected by calcified arteries, fast, metatarsal and toe eval
|
|
|
Doppler waveform analysis
|
patient in basal state, warm room, 4 or 8 MHz, 45-60 degrees angle to skin, obtain clean wavefrom |
|
|
Purpose of Exervise Stress test |
differentiate true vascular claudication from pseudo-claudication, borderline normal from abnormal, pts w. neuropathy and vascular disease determine which condition is limiting the patients walking |
