Asthma classifications Flashcards
Intermittent
sx= < 2x/wk, no interference w/ daily activity
nighttime= <2x/mnth
use of rescue meds= < 2 days /wk
lung fxn= FEV >80%
FEV/FVC normal
mild persistent
sx= > 2 days/wk, but not daily
nighttime= 3-4X/mnth
use of rescue= > 2 days/wk, but not daily and not more than once per da
lung fxn=same as intermitent
moderate persistant

night time= > 1 time/wk, but not nightly
use of rescue= daily
FEV> 60%
FEV/FVC reduced 5 %
severe persistent
sx= continual, extremely limited activity
nighttime= often 7X/wk
use= several times per day
lung fx= FEV <60%
FEV/FVC ration reduced > 10%
how do you dx astham
airflow obstruction is indicated by a decreased ratio of forced expiratory volume in 1 sec to forced vital capacity - if greater than 10% increase in FEV1 after bronchodilator therapy= dx!
ABG?
