Edema vs Lymphedema

Fluid Balance

Fluid moves freely b/t interstitial & intravascular spaces to

maintain homeostasis

4 types of pressure control fluid shifts across the capillary

membrane

Capillary hydrostatic pressure( the internal fluid pressure on

the capillary membrane)

Interstitial pressure (external fluid pressure on the capillary

membrane

Osmotic pressure-(fluid attracting pressure from protein

concentration within the capillary

Fluid Balance Interstitial osmotic pressure (the fluid attracting

pressure from protein concentration outside the capillary

Normally capillary hydrostatic pressure is >than plasma osmotic pressure at the capillary’s arterial end forcing fluid out of the capillary.

Capillary end the reverse is true(plasma osmotic pressure is >)

Edema results when balance is impeded with increased capillary permeability, lymphatic obstruction, increased capillary hydrostatic pressure, decreased plasma osmotic or interstitial fluid pressure

Pitting edema

Lymphatic Disorders

Lymphedema Excessive and persistent accumulation of extravascular

and extracellular fluid and proteins in tissue spaces

Caused by a disturbance of the water and protein balance across the capillary membrane

Increased concentration of proteins draws greater amount of water into interstitial spaces

Exceeds transport capacity of the lymphatic system, leading to lymphedema

Contributing factors for

Lymphedema Congenital Malformation

Infection and Inflammation

Obstruction or Fibrosis

Trauma, Surgery, Neoplasms

Radiation Therapy

Surgical Dissection of Lymph Nodes

Chronic Venous Insufficiency

Edema vs Lymphedema Normal response to inury. As

healing occurs fluid

decreases

Excess tissue fluid not yet

returned to circulatory syst.

Caused by circulatory

system problems such as

chronic venous insuffiency,

Does not leave a mark when

press (nonpitting)

Can be relieved by diuretics

in some cases

Lymphatic system is

impaired

Excess lymph trapped in

tissue

Body responds with slow

healing and at risk for

infections

Leaves a mark

Harmed by diuretics
