Flashcards in Hemodynamics Part I: Edema Deck (27):
1

vessel occlusion y excessive blood clot formation

thrombosis

2

where does the outflow of fluid usually occur within a capillary bed

arterial end of circulation

the return of fluid is at the venous end

3

increased fluid in the interstitial tissue spaces

edema

4

protein-poor fluid

transudate

5

hydrothorax

fluid in pleural space

6

hydropericardium

fluid in the space between the heart and pericardium

7

ascites (hydroperitoneum)

fluid in peritoneal space

8

increased hydrostatic pressure edema characteristics

generalized

characteristic of CHF

produces dependent edema

9

finger-shaped depression remaining after pressing on skin with finger

pitting edema

due to transient fluid displacement

10

protein most responsible for maintaining colloid osmotic pressure

albumin

11

liver failure of cirrhosis -->

decreased production of protein (albumin)

12

loss of protein via glomerular injury

nephrotic syndrome (> 3.5)

13

what does ascites result from?

advanced liver cirrhosis

14

describe anasarca

severe generalized edema

lack of oncotic pressure

earliest sign is periorbital edema

15

increased salt in circulation leads to (3) --->

- shift of fluid to intravascular space
- increased hydrostatic pressure due to expansion of fluid volume
- increased plasma water content results in decreased oncotic pressure resulting from dilution of albumin

16

inflammation edema characteristics

increased passage of fluid into the extracellular space

localized

usually exudate

17

lymphedema characteristics

localized

lymphatic obstruction due to inflammation or neoplasia

18

elephantitis due to wuchereria bancrofti

lymphedema

19

removal of axillary lymph nodes post-mastectomy

lymphedema

20

clinical manifestations of pulmonary edema

dyspnea
-sudden, orthopnea, cyanotic, air hunger, tachypnea

cough: copious sputum, frothy, blood tinged

pulse: tachycardic, boudning

crackles and JVD

21

observe: poorly defined pulmonary vessels, visible lung fissures, septal lines, thick bronchial wall, haziness on xray

interstitial pulmonary edema

22

observe: bilateral symmetric perihilar lung consolidation

alveolar pulmonary edema

look also for enlarged heart and pleural effusion

23

parenchymal edema may shift brain due to increased pressure and if generalized may push the brainstem down into the foramen magnum =

tonsillar herniation

24

causes of localized cerebral edema

abscess
neoplasm
trauma

25

causes of generalized cerebral edema

encephalitis
hypertensive crisis
obstruction of venous outflow
trauma

26

epidural is more likely------------- and subdural is more likely __________

epidural- arterial
subdural- venous

subarachnoid- into brain tissue, intraparenchymal hemmorhage

27

gross appearance of cerebral edema

distended, flattened gyri and narrowed sulci due to compression of brain against skull
