Welcome to Part 1 of our two-part podcast series on Adult Asthma Exacerbations. Given this past summers' increase in the number and size of forest fires leading to increased asthma presentations to the ED, we are joined by Dr. Leeor Sommer from North York General Hospital and Dr. Sameer Mal, an ED-Intensivist and Transport Physician from London, Ontario to discuss the most important aspects of ED asthma care. Together, we'll explore a systematic approach to managing patients presenting to the ED with asthma exacerbations. Our discussion will emphasize the critical role of a thorough history and physical examination in effectively stratifying patient risk and guiding treatment/disposition decisions. Additionally, we'll examine the importance of providing comprehensive discharge medications and instructions to mitigate both mortality and morbidity associated with asthma exacerbations. We answer questions such as: which patients, if any, require peak expiratory flow measurements in the ED? Why is it so important to add steroid MDI therapy to oral steroid therapy in patients being discharged from the ED after an asthma exacerbation? What are the most predictive variables to risk stratify patients with asthma exacerbations to help guide treatment and disposition? and many more. Stay tuned for Part 2, where we'll delve deep into the management of the crashing asthmatic.

Utilize adjuncts such as PoCUS and chest X-ray to help refine your differential diagnosis in conjunction with a thorough history and physical examination. Guard against diagnostic premature closure that might lead you to exclusively consider asthma upon hearing the term 'wheeze'.
