Flashcards in Unit 8 Deck (41):
1

atelectasis

collapse of part of lung leading to impeded filling

2

what type of problem is atelectasis

str problem

3

when is atelectasis permanent

if alveoli and wall are stuck together

4

3 types of atelectasis

obstr/resorptive
compression
contraction

5

what is obstr/resoprtive atelectasis dt

aw obstr (by mucous?) -> trapped air -> air is apsorbed into caps -> local collapse

6

what is compression atelec dt

ext p on lungs causing collapse

7

what is contraction atelec dt

lung trauma -> healing pulls area of injury together by depositing scar tissue -> pulls ends together -> contraction -> collapse of part of lung

8

mnfts of atelec

dyspnea
tacnypnea
dec chest expansion
inc hr

9

what is dyspnea rt in atlec

l/o lung capacity

10

what is tachypnea rt in atlec

dec vent

11

is tachypnea in atlec compensatory

yes

12

why is there inc hr in atlec

collapsed areas cannot expand leadint to dec chest expansion

13

is inc hr in atlec compensatory

yes

14

dx for atlec

px
cxr (large area)
ct (small area)
bronchoscopy

15

tx for atlec

tx cause

16

plueral effusion

accum of fluid in plueral space

17

what is pleural effusion dt

dt abn seepage or drainage

18

what is pleural effusion directly rt

transcap exch/seepage

19

exudate in plueral effusion

inflm fluid with inc protein content

20

transudate in PE

non inflm fluid with dec protein content

21

empyema in PE

purulent fluid dt bact inf

22

hemothorax in PE

blood

23

chylothorax in PE

lymph

24

Et of PE

usually CHF
infc, ca, infarct

25

why may infection cause PE

inc exudate

26

why may ca cause PE

tumor->obstr

27

why may infarct cause PE

obstr

28

why may obstr cause PE

areas prior to obstr have inc in fluid -> impaired TCE

29

how does fluid enter parietal memb

parietal caps

30

where does excess fluid drain into

parietal lymphatics

31

what happens when fluid entry into parietal caps exceeds drainage

PE

32

what are mnfts of PE based on

cause and vol

33

3 main mnfts of of PE

dyspnea
plueritic pain
lung compression

34

why does dyspnea occur in PE

poor ventilation

35

why does plueritic pain occur in PE

fluid accum applies in P in lungs

36

dx of PE

XR ( large vol) US, CT

37

Tx of PE

identify cause

38

how do you identify cause of PE

fluid analysis via paracenthesis

39

when do you use a chest tube to tx PE

for slower, long term drainage if problem cant be fixed quickly

40

when can PE fluid not be drained

if fluid has inc viscosity, -> sx

41

what if PE is a reoccuring problem

palliative pts only, use a sclerosing agent to remove space between membs
