Pulmonary Disorders Flashcards
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
What are the names of common ICS?
-Key suffix -sone
Beclomethasone
Ciclesonide
Flunisolide
Fluticasone
Mometasone
What are the names of common SAMAs?
Ipratropium (Atrovent)
What are some common names of LAMAs?
-Aclidinium bromide
-Glycopyrrolate
-Revefenacin
-Tiotropium
-Umeclidinium
What are some common names of SABAs?
Albuterol
Levalbuterol
What are some names of common LABAs?
Arformoterol
Formeterol
Indaceterol
Olodaterol
Salmeterol
What are the three LTMs on the market?
Montelukast
Zafirlukast
Zileuton
What IgE-binding inhibitor is used in asthma
Omalizumab
What IL-4 antagonist is used in asthma? When is it indicated
Dupilumab, as an add-on in those with eosinophilic asthma or if OCS-dependent
What IL-5s antagonists are used in asthma? When are they indicated?
Mepolizumab
Reslizumab
Benralizumab
-Eosinophilic phenotype asthma (>150-400 /mm3 if PT is not taking daily systemic steroids)
Patient has a FEV1 82% and wakes up 3 times a night a diagnosis of asthma what NAEPP classification of asthma is she?
Mild persistent
What medication class is best recommended?
ICS/formeterol PRN
If a patients mild persistent asthma is not well controlled with ICS/formeterol what should be added to therapy?
Montelukast (LTM)
If an 8-yo is experiencing 1-2 daytime asthma symptoms weekly and waking twice weekly coughing what should be added to Albuterol PRN?
Fluticasone low-dose twice daily
How are LABAs indicated to be used per the FDA safety announcement?
Use of LABAs in asthma without ICS is contraindicated because of increased risk of severe worsening of asthma symptoms that can lead to hospitalization and death
-Always try to step down from LABAs as asthma symptoms are controlled
When are personal best peak expiratory flow rates used? (PEFR)
To assess asthma exacerbations and use an asthma exacerbations action plan
What PEFR indicates seeking medical attention immediately?
PEFR 50%
How should mild to moderate asthma exacerbation be treated?
-O2 to reach 93-98%
-Inhaled SABA every 20 mins for up to 4 hours then every 1-4 hours
-OCS if no response immediately or if PT recently took an OCS
