Asthma results in episodic reversible
Narrowing and inflammation of the airways
What are the clinical hallmarks of asthma?
Episodic wheezing associated with dyspnea, cough, and sputum production
What is the most common symptom of asthma?
Cough
What PEF values indicate the need for quick-relief medication?
50-79% predicted or personal best
What PEF values indicate the need for immediate medical care?
<50%
To assess asthma severity, a SABA is inhaled up to
2 treatments 20 mins apart of 2-6 puffs by MDI or nebulizer treatments
Trial of a bronchodilator should provide evidence that airflow obstruction is
At least partially reversible
Spirometry includes which 2 values?
Peak expiratory flow (PEF) and FEV1
What are differential diagnoses?
Upper respiratory - croup, vocal cord dysfunction
Lower respiratory - COPD, pneumonia
Cardiovascular - valvular disease, cardiomyopathy
GI - GERD
All patients should receive a
Reliever medication (bronchodilator)
Reliever medications include
SABAs, low-dose ICS/formoterol, and short acting anticholinergics
Controller medications include
ICS/LABA combinations
What are add-on controller medications?
