Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung disease characterized by progressive airflow limitation and tissue destruction (Agarwal et al., 2023). According to Rodrigues et al. (2021), the main pathophysiological changes include alterations in cell functions, which leads to the generation of oxidative and inflammatory microenvironment resulting in chronic inflammation in the airways, destruction of lung parenchyma (emphysema), and disruption of the normal repair and defense mechanisms, leading to narrowing of the small airways (bronchiolitis). These changes result in airflow limitation and air trapping, which cause shortness of breath or dyspnea, particularly during physical activities, as the lung's capacity to exchange air is compromised. The cough Mr. Brown is experiencing is likely due to the increased mucus production in response to inflammation and irritation of the airways.
The vital signs of Mr. Brown show a respiratory rate (RR) of 26 breaths per minute, which is higher than the normal range (12-20 breaths per minute), indicating that he is tachypneic, which is common in COPD exacerbations. His oxygen saturation (SpO2) of 91% is below the normal range (95-100%), suggesting that he has hypoxemia, a hallmark of COPD exacerbation
