type 2, hypercapnic failure
what is a silent chest
no respiratory sounds, very ominous finding
what is the significance of a drop in BP during inspiration
pulsus paradoxus
emergency
what would you expect PFT results to be in an asthmatic
very low FEV1, minor low FVC
FEV1/FVC <70%
how would you check for inducability of asthma during a PFT
administer methacholine and if FEV1 reduces by >20%, this is suggestive of asthma
how do you check reversibility of asthma during PFT
give bronchodilator and >12% increase in FEV1 is suggestive of asthma
what testing can you use during asthma exacerbations to test severity
Peak expiratory flow rate (PEFR)
<40% of predicted value = severe exacerbation
what are the questions to determine severity of symptoms
Daytime symptoms >2X/week
Symptoms at night
SABA inhaler > 2X/week
symptoms interferes with ADLs
