Understanding Asthma Exacerbations
Asthma exacerbations are episodes characterized by increased respiratory distress, which often results from allergens, infections, or physical exertion. Patients typically present with symptoms such as cough, wheezing, chest tightness, and shortness of breath, and the severity of these symptoms can vary greatly. In evaluating a patient experiencing an exacerbation in the emergency department, it is crucial to assess not only the asthma symptoms but also to rule out other potential conditions like anaphylaxis, pneumonia, or congestive heart failure, as these can mimic asthma presentations. Gathering a thorough history, such as previous treatments and any recent respiratory distress, is essential in determining the underlying causes and aiding in effective management.
