Is a cough with asthma usually productive?
No, it is usually productive with COPD
What measure in lung function differentiates COPD from asthma?
COPD has persistent airflow limitations that is not reversible (post-brochiodilator FEV1/FVC <0.7)
Define FEV1, what is normal?
Maximum volume of air exhaled forcefully in the first second of maximum expulsion
Normal is >/=80%
Define FVC
What is normal?
Maximum volume of air that can be exhaled after full inspiration
Normal is empty 80% of air in <6 secs
Define FEV1/FVC
What is normal?
Percentage of lung capacity able to be expelled in one second
Normal usually 75-80%
What is the cutoff from moderate persistent to severe persistent asthma in FEV1/FVC and FEV1 (percent of normal)
<75%, <60%
What is step 1 of treatment of asthma?
Low-dose ICS+formeterol PRN when >12 yo
What is step 2 of treatment of asthma?
Low-dose ICS daily or low dose ICS + formeterol PRN
What is step 3 of treatment of asthma?
Low dose ICS +LABA
What is step 4 of treatment of asthma?
Medium dose ICS+LABA
What is step 5 of treatment of asthma?
High-dose ICS+LABA and add-on tiotropium or omalizumab or IL-5 antagonist if eosinophilic asthma
