ASTHMA2AsthmaIntroductionAsthma is an airway disease that has significant inflammation and airflow obstruction (Hammer & McPhee, 2014). This paper is a brief overview of both acute asthma and chronic asthma. The pathophysiology of acute asthma exacerbation and chronic asthma is discussed. While the two seem similar, there are some noticeable differences in the way the bodyadjust to each process. The diagnosis and treatment for each disorder will be explained. Acute Asthma Exacerbation“Asthma is a chronic inflammatory disorder of the airways with hyperresponsiveness, and reversible airflow limitation” (Rodrigo, Rodrigo, & Hall, 2004). Acute asthma exacerbations are diagnosed by the severity of the symptoms and go from mild to subset/life threating (Pollart, Compton, & Elward, 2011). The pathophysiology of asthma starts with the “activation of the local inflammatory cells, like the mast cells and eosinophils” (Hammer & McPhee, 2014). The acute -acting mediators then cause smooth muscle contraction, mucus hypersecretion, and local swelling. Due to the smooth muscle hyperresponsiveness and inflammation the airways become narrow, which increases airway resistance. “Airway obstruction increases resistance to airflow and decreases flow rates especially expiratory flow. Impaired expiration causes air trapping, hyperinflation distal to obstruction, and increased work of breathing. Continues air trapping
