Peripheral Cirulation Flashcards
What is the function of peripheral circulation
transports blood to the body
-transports O2 to the tissues
-transports O2 from the tissues to the lungs to atmosphere
explain generally what happens with blood flow to exercising muscles what is brought to the muscle and what is removed
Blood brings: oxygens and nutrients glucose
Removes: CO2, lactic acid, leads to heat dissipation
What pathologies affect the transport of O2 in the vasculature
Peripheral vascular disease or peripheral arterial disease
PAD affects ____ of americans aged 65 years and older
12-20%
what is the claudication scale a measure of and describe each level
measure of PVD or PAD
1-4
1- definite discomfort pain, but only at initial or modest levels
2- moderate discomfort or pain from which the patients attention can be diverted
3- intense pain from which the patient’s attention cannot be diverted
4- excruciating and unbearable pain
what does arterial brachial index measure
measure of plaque formation in the arteries
ABI=
highest pressure in RIGHT foot/ Highest pressure in both arms
a health individual will have less than ___ difference between arms when measuring ABI
10mmhg
more than 10 mmhg between arms is considered
stenosis
PAD causes arteries to ____ and ______ blood flow

what is one difference between pain symptoms in PAD compared to DVT
PAD pain during activity
DVT pain at rest
what is normal ABI?
0.91+
ABI of 0.70-0.90
mild obstruction
ABI of 0.40-0.69
moderate obstruction
