|
the TYPE of EDEMA where chemical mediators play a role
|
INFLAMMATORY edema
|
|
|
the TYPE of EDEMA where HEMODYNAMIC FORCES across the capillary wall controls swelling
|
NON -inflammatory edema (no WBC's)
|
|
|
Drop in protein (plasma colloid osmotic), retaining water and salt due to JG apparatus, blocked lymphatics (cancer, inflammation, etc.), or INCREASED hydrostatic pressure are all signs of
|
NON - inflammatory edema (no WBC)
|
|
|
NON-inflammatory edema could be said to be ____________-related.
|
Gradient
|
|
|
Describe NON-inflammatory edema in terms of fluid collection?
|
a NET INCREASE (accumulation) of EXTRA CELLULAR FLUID because more fluid going into vessel than out
*this card probably should say "more going out of the vessel than in" but I have to check the notes |
|
|
Describe a clot
|
Impaired venous outflow because of a clot is called VENOUS THROMBOSIS
BLOCKAGE OF A VEIN |
|
|
Increased HYDROSTATIC pressure due to THROMBOSIS...
|
a CLOT has formed, blocking the vein and causing DEEP VEIN THROMBOSIS
|
|
|
Increased HYDROSTATIC pressure not only caused by deep vein thrombosis due to a clot blocking a vein, but also can result from 2 organ FAILURE:
|
RIGHT SIDED HEART FAILURE -where does the fluid go when it can't get into the heart? Yup, the tissues.
RENAL FAILURE: + dysfunction due to a higher VOLUME of blood/fluid so the fluid compartment balance of the kidney crashes. |
|
|
Regarding SALT & WATER retention, you make too much _______, either because of renal failure or heart failure, and Big Aldosterone is gonna come kick out those K+ bums and grab the Salty girls all for himself.
|
RENIN
*causes edema because... JUXTAGLOMERULAR APPARTATUS overfunction, either due to kidney fail or heart failure. Doesn't matter which. |
|
|
Why would Secondary/heart disease cause and increase in blood pressure and INCREASE EDEMA?
|
ATHEROSCLEROSIS in renal artery
secrete RENIN due to initially LOW BP in kidneys, this skyrockets the BP and causes edema. |
|
|
__________edema is most often due to right sided heart failure and involves the lower extremities because the blood cannot get back in!
|
DEPENDENT
|
|
|
___________edema is all edematous, most often due to RENAL failure and is more severe than dependent edema.
|
ANASARCA/GENERALIZED
|
|
|
ANASARCA presents with __________ along the tibia and ankle and __________ edema around the eyes.
|
PITTING & PERIORBITAL edema = anasarca/general edema
*severity based on time it takes for tissue to restore/pop up |
|
|
DEPENDENT edema is
|
RSHF
|
|
|
GENERALIZED edema is
|
RENAL w/ Periorbital and Pitting edema
|
|
|
ASCITES is
|
KWASHIKOR'S (malnutrition)
|
|
|
When blood does not return to the heart from the lungs, ___________ edema results.
|
PULMONARY
|
|
|
Why would blood return to the lungs in pulmonary edema?
|
The LEFT SIDE OF THE HEART IS FAILING.
|
|
|
signs and symptoms of pulmonary edema:
DROWNING IN BLOOD... |
EDEMATOUS (red)
PROTEINACEOUS (frothy) sputum with chest pain DROWNING |
|
|
ACTIVE increased blood flow to a tissue is called ___________.
Example? Does it cause edema? |
HYPEREMIA
Vasodilation No, happens all the time due to chemicals or sympathetics. |
|
|
HYPEREMIA =
|
ACTIVE, NO edema
|
|
|
CONGESTION =
|
PASSIVE, ALWAYS EDEMA (ISCHEMIA)
|
|
|
What causes right sided heart failure with passive congestion?
|
heart cells in the LUNGS have macrophages full of HEMOSIDERIN. RBC's leak into alveoli, macrophages eat them and the hemosiderin dyes them a RED/BROWN COLOR of lung.
|
|
|
NUTMEG LIVER ...
LIVER BACKED UP WITH BLOOD |
passive/CONGESTION of liver because Right side of heart is not draining the venous system. Right sided blood must go into liver before rest of the body.
|
|
|
T.E.V.A.T.
|
5 causes of hemorrhage:
Trauma Aneurysm Erosion Vitamin Thrombocytopenia |
