Edema Flashcards
Edema from increased capillary filtration pressure is usually caused by
increase in blood volume
Where is edema from increased capillary filtration (hydrostatic) pressure usually found
in patients with congestive heart failure
What is dependent edema
accumulation of fluid in the lower parts of the body
What usually causes dependent edema
venous insufficiency from conditions like thrombophlebitis
What causes edema from decreases in capillary coloidal osmotic pressure
inadequate production or excessive excretion of plasma proteins like albumin
What protein exerts the most osmotic pressrue
albumin
What usually causes a decrease of plasma protein production relating to a decrease of capillary colloidal osmotic pressure
damage to the liver so it can’t make them
starvation so you dont get enough amino acids to make them
Where are most plasma proteins lost
the kidney
Example of a disease that can cause edema from decreased colloidal osmotic pressure
nephrotic syndrome
How does edema from increased capillary permeability happen
intergrity of the capillary wall is damaged
capillary pores enlarge
When can edema from increased capillary permeability happen
burn injuries inflammation toxins infection vessel disease from HBP and diabetes
Edema an obstruction of lymphatic flow is caused by what
when particles that are used to traveling through the lymph system to get back to the blood stream can’t because of a problem with the lymph, so osmolarity in the interstitial space increases and pulls water to it
What the technical name for Edema caused by an obstruction of lymphatic flow
lymphedema
What can cause lymphedema
cancer obstructions
removal or damage to lymph system
What is pitting edema
when the fluid in free moving so you can push into the swollen area and a “pit” will stay there for a little bit
What is nonpitting edema
the opposite of pitting
skin becomes firm and discolored
Edema from decreased plasma protein Oncotic pressure might happen from
liver failure because the liver is no longer making enough plasma proteins
Whats the pitting scale
2mm = +1 disappears immediately
2-4mm = +2 few second rebound
4-6mm = +3 10-12 sec rebound
6-8 mm = +4 more than 20 seconds
What do men use to easily check for edema
base of pinky nail to the tip is about 1 cm
What do women use to easily check for edema
pointer finger base of nail to tip is about 1 cm
At the end of the day, where is a common place to have a little edema
feet
Are prego women checked for edema more often
yes
