Flashcards in Congestion and Oedema Deck (28):
1

What is congestion?

Relative excess of blood in vessels of a tissue/organ

2

Is congestion a passive process?

Yes

3

What is an example of local acute congestion?

DVT

4

What is an example of local chronic congestion?

Hepatic cirrhosis

5

What is an example of general acute congestion?

Congestive cardiac failure

6

What is hepatic cirrhosis?

A disease in which the healthy tissue in the liver is replaced by scar tissue eventually rendering the liver ineffective

7

What are 2 causes of hepatic cirrhosis?

Alcohol
Hepatitis B

8

What is congestive cardiac failure?

When a pump is ineffective stopping the heart from being able to fully eject blood from the ventricles

9

What type of drug do you use to treat the fluid overload in the veins caused by congestive cardiac failure?

Diuretics

10

What are 2 of the consequences of congestive cardiac failure?

Central venous congestion in the liver
Pulmonary oedema

11

What pressure is the constant movement of fluid through capillary beds driven by?

Hydrostatic pressure from the heart

12

What pressure is the constant movement of fluid through capillary beds balanced by?

Osmotic pressures

13

What is an oedema?

The accumulation of fluid in the extra-vascular space

14

What is peripheral oedema?

Build up of interstitial fluid in tissues

15

What is an effusion?

Accumulation of fluid in the body cavities

16

What are transudates caused by?

Alterations of haemodynamic forces across the capillary walls

17

What is the constituents of transudates? (3)

Low protein/albumin
Lots of water
Lots of electrolytes

18

Is the specific gravity of transudates high or low?

Low

19

What are exudates?

Fluids which enter into areas of inflammation?

20

What is the constituents of exudates? (3)

High protein/albumin
Normal water
Normal electrolyte

21

Is the specific gravity of exudates high or low?

High

22

Are the following examples of exudates or transudates:
Tumour, inflammation, allergy?

25

In pulmonary oedema where does the fluid accumulate in the lungs?

The alveolar spaces

26

What pressure is responsible for pulmonary and peripheral oedema?

Hydrostatic pressure

27

What pressure is responsible for lymphatic blockage?

Hydrostatic pressure

28

Are the following examples of exudates or transudates:
Permeability oedema?

Exudates
