Day 2 Flashcards
In a 24 hr period how much of the circulating proteins will leave the blood into interstitial tissue?
50%
What supports venous return?
Diaphragmatic breathing Adjacent arteries pulsating Muscle pump Suction effect of the heart Valves
What causes insuffancies of lymphatic system?
Transport capacity bring lower than lymphatic loads.
It is normally 10 times higher than amount of lymph produced.
What is functional reserve in the lymphatic system?
Back up of lymphatic system
Amount of compensation
As long as lymphatic load is below what you will never see swelling.
Transport capacity
Lymph time volume is what?
Amount of lymph transported in a unit of time.
How fast it’s moving.
What is dynamic insuffancy?
Healthy lymphatic system is overwhelmed High volume insuffancy LL of H2O > TC Max LTV = TC MLD increases LTV of collectors, but cannot increase LTV more than max capacity
Will only show edema
What is mechanical insuffancy?
Unhealthy lymphatic system
TC drops below the normal amount of LL (anything below 100% - only see lymphedema if TC is below 10%)
Low volume insuffancy
What causes mechanical insuffancy?
Surgery Radiation Infections Trauma CVI congenital malformation
What is combined insuffancy?
Mechanical insuffancy with sudden onset of swelling (in 1 day) due to external factor.
Symptoms of dynamic insuffancy?
Healthy LS TC is normal LL of H2O is higher than normal TC Protein concentration in tissue is normal High volume insuffancy MLD/CDT not indicated Max LTV = TC Edema
Mechanical insuffancy symptoms
Unhealthy LS
TC is subnormal
LL could be normal but higher than subnormal TC
Protein concentration in tissue is higher than normal
Low volume insuffancy
MLD/CDT = TCsubnormal
Lymphedema
