Master the pharmacological and pathophysiological decision-making required for severe and refractory asthma exacerbations. This advanced module moves beyond basic algorithms to dissect the mechanisms of action, dosing strategies, and critical controversies surrounding SABAs, SAMAs, corticosteroids, magnesium, ketamine, heliox, and epinephrine. Designed for paramedics and emergency physicians, it emphasizes rapid risk stratification, the identification of near-fatal phenotypes (including AERD and anaphylaxis overlap), and the prevention of post-intubation collapse through a deep understanding of dynamic hyperinflation and auto-PEEP. Grounded in pan-Canadian consensus and current evidence, this content prepares clinicians to manage the high-stakes transition from pre-hospital care to definitive airway management.
