Edema And Shock Flashcards
Which are the starling forces and what determined them?
The Starling forces determine fluid movement through capillary membranes, there are 4 forces: Pc, Pi, TTc, TTi.
Which Starling’s force pushed fluid out of the capillary?
Pc = Capillary pressure.
Which Starling’s pressure pushed fluid into of the capillary?
Pi = Interstitial fluid pressure.
Which Starling’s pressure pull fluid into of the capillary?
TTc = Plasma Colloid Osmotic Pressure.
Which Starling’s pressure pull fluid out of the capillary?
TTi = Interstitial fluid colloid osmotic pressure.
What is the Kf?
Filtration constant, measure of capillary permeability.
What’s going to cause an increase in a hydrostatic pressure inside the capillaries?
1) CHF (Elevated of the central venous pressure).
2) Venous thrombosis.
3) Compression veins.
4) Sodium and water retention.
What’s going to cause an increase capillary permeability ?
Infections and septic shock.
Toxins.
Burns.
What’s going to cause an decrease plasma colloid osmotic pressure?
Nephrotic syndrome.
Liver disease.
Protein malnutrition.
Protein-losing enteropathy.
What’s going to cause an increase interstitial colloid osmotic pressure?
Lymphatic obstruction.
Which are the major causes of edema?
1) Increase capillary pressure.
2) Increase capillary permeability.
3) Increase interstitial fluid colloid osmotic pressure.
4) Decrease plasma proteins.
What is the definition of edema?
Excess of fluid outflow into interstitium.
What is a pitting edema?
Excess amount of fluid in absence of additional colloid.
What causes Non-pitting edema?
Colloid in interstitial fluid.
What is the Transudate ?
Protein-poor edema fluid caused by increased capillary pressure or decreased plasma protein.
What is the Exudate?
Protein-rich edema fluid caused by increased capillary permeability.
