Asthma and COPD are two of the most common chronic respiratory diseases nurses will encounter — but both can escalate into life-threatening emergencies if not managed properly. In this lesson, we’ll review the basics of asthma, from airway inflammation and bronchodilator use to the critical warning sign of absent wheezing in status asthmaticus. We’ll also cover COPD, focusing on carbon dioxide retention, oxygen therapy targets, and how long-term complications like pulmonary hypertension and cor pulmonale develop. By the end, you’ll have a solid framework for recognizing, treating, and anticipating complications in these key pulmonary conditions.
