obstructive exam features
airflow issues» turbulence, increased expiator, decreased breath sounds,
categories of obstructive acronym
FACES
FACES
foreign body/upper airway, asthma, chronic bronchitis/bronchiectasis, emphysema, small airway disease (bronchiolitis)
Factors for increasing R
increase SM tone, decreased radiums, SM hypertrophy, mucus
emphysema insp/exp
inps: less alveoli, less pull open, higher r. exp: no recoil, difficulty exp
Palv =
Pel+Ppl
why does airway collapse in emph forced expiration
transmural pressure hits 0 in compressible location… hyperinflate
resp def
decreased distend ability of lungs, pleura, or chest wall
compliance in restrictive
DECREASED
exam resp
low lung V but no wheezing/insp/exp… not airway issue
categories of resp
