edema Flashcards
what is edema
build up of fluid in interstitial fluid ( fluid in-between cells)
can be localized or generalized
pitting edema or non pitting
what are the causes of edema
increase in hydrostatic pressure
decrease in oncotic pressure
lymphatic channel obstruction (lymphedema)
capillary permeability
fluid movement into tissues
what causes increased capillary permeability
burns/inflammation
what leads to increased tissue and oncotic pressure
loss of plasma proteins in interstitial fluid
decreased transport of capillary filtered proteins
lymph obstruction
what causes decreased capillary oncotic pressure
loss of plasma proteins in interstitial fluid
malnutrition
decreased synthesis of plasma proteins
increased loss of plasma proteins
increased na+ and h2o retention
what is decreased synthesis of plasma proteins
cirrhosis and malnutrition
what is increased loss of plasma proteins
nephrotic syndrome
what is increased na+ and h2o retention
dilution of plasma proteins
