|
Term
What causes tissue death in PVD |
|
Definition
|
|
Term
Adequate blood flow is dependent upon 4 factors |
|
Definition
condition of the blood vessels, rate of the blood flow, metabolic needs of the tissues, nervous system activity |
|
|
Term
Sympathetic nervous system |
|
Definition
directs hypothalmus regulates and causes vasoconstruction |
|
|
Term
|
Definition
main neurotransmitter for sympathetic vasconstriction |
|
|
Term
|
Definition
released from adrenal medulla to cause vasoconstriction and is released in high doses |
|
|
Term
|
Definition
formed by interation of renin and circulating hormone to potent substance that changes to cause vasoconstruction |
|
|
Term
|
Definition
heart contractions weakens |
|
|
Term
what are alterations in Blood and Lymph Vessels? |
|
Definition
Plaque narrows blood vessels passage and causes peripheral resistance, less blood gets to extermities, slowed rate causes turbulences and increases viscosity thickens blood and causes clots |
|
|
Term
Circulatory insufficency of the extremities: Hydrostatic |
|
Definition
pushing pressure decreased due to peripheral resistance (vessel/valve problems) |
|
|
Term
circulatory insuffciency of the extermities: Osmotic |
|
Definition
pulling pressure decreased less able to pull fluid from the intersitital space back into the capillaries |
|
|
Term
|
Definition
most common of disease of the arteries,means hardining of the arteries |
|
|
Term
Etiology of reduced blood flow |
|
Definition
a process where the nuscle fibers of the endothelial lining of the walls of the smaller arteries become thickened |
|
|
Term
|
Definition
involves a different process affecting the intima layer of the larger arteries |
|
|
Term
ATHEROsclerosis causes what? |
|
Definition
narrowing of the lumen stenosis and possible obstruction by thrombus |
|
|
Term
ATHEROsclerosis process is what? |
|
Definition
changes consist of the accumulation in lumen of atheromas or plaques make up of, lipids,calcium,blood components,carbs,fibrous tissues, although the pathological process of arter/athero differ rarely one dose not occur with out the other |
|
|
Term
recommended levels of lipid profile? |
|
Definition
low density (bad) want under 100mg/dl diabetics HTN Atherosclerosis or smoker under 70: high density(good)more than 60 diabetics same:cholesterol under 200 diabetics same; triglycerides under 150 and diabetics same |
|
|
Term
What is Buergers Disease? |
|
Definition
it is characterized by recurring inflammation of the small arteries and veins of the lower/upper extremities |
|
|
Term
Buergers disease results form what |
|
Definition
thrombus formation and occulusion of the vessels, very painful,relieved by rest |
|
|
Term
who dose Buergers disease effect the most? |
|
Definition
men between 20-35 it is an autoimmiune diseases,and tobacco is main cause/aggravating factor because it vaso constricts the arteries |
|
|
Term
buergers disease can progress to what? |
|
Definition
ulcers,gangreen and amputation |
|
|
Term
What kind of disease is Raynaud's Disease |
|
Definition
it is a ARTERIOSPASTIC disease |
|
|
Term
what is raynaud's disease |
|
Definition
localized intermittent episodes/vasospasms of arterioles and vasoconstriction of small arteries of the hand and feet |
|
|
Term
|
Definition
most common is women ages 16-40 yrs occurs more in cold climates and winter results in color pallor and temp cold and pain changes bilaterally in hands and feet |
|
|
Term
what is the color sequence in raynaud disease |
|
Definition

|
Term
PAD and PAOD chief symptom? |
|
Definition
intermittent claudication |
|
|
Term
what % of vessel must be obstructed to have symptoms occur in PAD and PAOD? |
|
Definition
|
|
Term
what happen in PAD and PAOD |
|
Definition
pain due to the inability of the arterial system to provide adequate blood flow to tissues? |
|
|
Term
Where dose the pain occur in PAD and PAOD? |
|
Definition
muscles in groups in joint |
|
|
Term
Where dose the pain occur in PAD and PAOD? |
|
Definition
muscles in groups in joint BELOW THE OCCLUSION/STENOSIS OF THE DISEASE |
|
|
Term
what kind of pain is common in PAD AND PAOD? |
|
Definition
cramplike muscular pain in extermities consistently occurs with the same amount of activity and relieved by rest |
|
|
Term
What are the S&S of PAD and PAOD |
|
Definition
it is REST PAIN, severe pain in the extremity at night time it worsens when the clients is at rest |
|
|
Term
what dose rest pain indicate? |
|
Definition
there is a severe degree of arterial insufficency and critical state of ischemia |
|
|
Term
what are the 6 P's in ischemia and what is ischemia? |
|
Definition
ischemia is deficient blood supply to the body part and the p's are Pain, Pallor, pulselessness(popilital, dorasalis, posterior tabial) Parathesia(tingling, numbness) Paralysis, Polkilothemia (coolness) |
