Rush Edema Flashcards
Edema hydrostatic pressure
Heart failure
Edema oncotic oressure?
Nephrotic synd
liver cirrhosis
edema vascular permeability
burns
infections
edema via lymphatic obstrucrions
tumor
filariasis
posteadiation fibrosis
breast cancer (post-lymphadenectomy)
edema via sodium and water retention
renal disease
renal hypoperfusion
edema drains to where
thoracic duct to left subclavian vein
hydrostatic pressure out because of
increase intertitial fluid pressure
the pressure because if inc interstitial fluid pressure
plasma colloid osmotic pressure
hydrostatic pressure is at? and interstitial pressure is at?
hydro is at artery
intersitital is at venous
the force across capillary wall
starling forces
+ and - means in capillary pressure
+ favors filtration
- opposes filtration
pc and pi means? and pi c and pi i?
pc and i are capillary or interstitial hydrostatic press
pi c and i are capillary or interstitial oncotic pressure
basta p = hydrostatic
basta pi = oncotic
c is for capillary
i is for interstitial
transudate patho, vasc perm, protein leak, protein content, specific grav, fibrin, inflamm cells, and gross app
starling forces pathophysiology
normal vascular permeability
low leak plasma
less than 1.012 sg
no fibrin
no inflammatory cells
serous and clear appeaeance
exudate patho, vasc perm, protein leak, protein content, specific grav, fibrin, inflamm cells, and gross app
high vascular permeability pathophysiology
increased vascular perm
plasma leak present
high protien content
more than 1.012 sg
yes fibrin
yes inflamm cells (WBC)
serous, fibrinous, purulent pus, hemorrhagic
criteria that differenciates exudate and transudate
lights criteria
if the lights criteria is mrt then what is the pleural fluid?
exudate
whats the criteria if:
protein by serum protein
LDH divided by serum
LDH compared to top value serum LDH
> 0.5
0.6
0.7
most common sites of effusion
subcutaneous tissue
lungs
brain
body cavities
location of edema influenced by gravity
dependent edema
depression on pressure due to displacement if interstitial fluid
pitting edema
occurs in renal faulure bcs area has lots of loose connective tissue
preorbital edema
characteristics of an effused lung
heavy 2-3x weight
frothy and bloody
characteristics of effused brain
narrowed sulsci
flattened gyri
morohology of effused body cavity
pleura (hydrothorax)
peritoneum (ascites)
pericardium (hypopericardium)
