Unit 8 Flashcards
atelectasis
collapse of part of lung leading to impeded filling
what type of problem is atelectasis
str problem
when is atelectasis permanent
if alveoli and wall are stuck together
3 types of atelectasis
obstr/resorptive
compression
contraction
what is obstr/resoprtive atelectasis dt
aw obstr (by mucous?) -> trapped air -> air is apsorbed into caps -> local collapse
what is compression atelec dt
ext p on lungs causing collapse
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
mnfts of atelec
dyspnea
tacnypnea
dec chest expansion
inc hr
what is dyspnea rt in atlec
l/o lung capacity

dec vent
is tachypnea in atlec compensatory
yes
why is there inc hr in atlec
collapsed areas cannot expand leadint to dec chest expansion
is inc hr in atlec compensatory
yes
