Obstructive Lung Disease Overview Flashcards
flow-volume curve in obstructive lung disease
- lower peak expiratory flow
- scooped out appearance
why do you have a scooped out appearance in obstructive lung disease on the flow-volume curve
- you have trouble getting the air out
FEV1/FVC of obstruction
- below 70% predicted
severity of obstruction is based on
- FEV1
RV in early obstruction
TLC in early obstruction
result
- some increase in RV
- TLC the same
- breathing at slightly higher volumes
RV in COPD
TLC in COPD
result
- RV much higher. will trap more air
- TLC higher
- higher lung capacity and barrel chests
obstructive lung diseases
- asthma
- COPD
- bronchiectasis
branches of COPD
- bronchitis
- emphysema
asthma is a disease of the airways characterized by
- airway inflammation
- reversible airflow obstruction with bronchodilator
- airway hyperresponsiveness
COPD characterized by
- airflow limitation that is not fully reverisble
airflow limitation is ____________ and associated with an enhanced ____________- of the lungs to noxious particles or gases
- progressive
- abnormal inflammatory response
COPD produces significant _____ consequences
- systemic
bronchiectasis is a clinical syndrome of
- productive cough with lots of sputum
- dilation of airways
is bronchiectasis reversible
- no and not curable
- but manageable
