A2 - Rahul G., Patwari PY - 2014 T2 - Clinical Emergency Medicine AB - Patients with severe asthma exacerbations may have such severe restriction of airflow that they do not exhibit wheezing on examination.Beta-2 agonists are the mainstay of treatment for acute asthma exacerbations.Corticosteroids should be given to patients who do not respond initially to beta-2 agonists and in those with moderate to severe exacerbations.Peak expiratory flow rate and forced expiratory volume in 1 second are objective measures of the severity of a patient's asthma exacerbation and should be followed serially to measure improvement.
