COPD - Nursing Case Study

Pathophysiology

• Primary mechanism: Airway inflammation and narrowing—Chronic exposure to irritants like cigarette smoke leads to persistent inflammation of the airways, causing them to narrow and obstruct airflow, making breathing difficult.

• Secondary mechanism: Alveolar destruction—The destruction of alveoli (air sacs) reduces the surface area for gas exchange, leading to impaired oxygen uptake and carbon dioxide elimination, which contributes to respiratory insufficiency.

• Key complication: Air trapping and hyperinflation—Due to obstructed airflow, air becomes trapped in the lungs, leading to hyperinflation, which increases the work of breathing and can result in respiratory muscle fatigue and diminished exercise tolerance.

Section 1

Change in Patient Status:

During the morning assessment, the patient exhibited increased respiratory distress. His respiratory rate had risen to 28 breaths per minute, and he appeared visibly anxious and using accessory muscles to breathe. Despite being on supplemental oxygen at 2 liters per minute via nasal cannula, his oxygen saturation remained low at 86%. Auscultation revealed diminished breath sounds bilaterally with scattered wheezes and crackles, suggesting possible fluid accumulation or further airway obstruction. The patient's heart rate had increased to 108 bpm, and he reported feeling more fatigued and unable to complete even basic activities without becoming breathless.

In light of these changes, the clinical team decided to order a chest X-ray and repeat arterial blood gas (ABG) analysis. The chest X-ray revealed hyperinflated lungs with flattened diaphragms and signs of a possible acute exacerbation of COPD. The ABG results showed a pH of 7.32, indicating respiratory acidosis, with elevated PaCO2 of 55 mmHg and low PaO2 of 55 mmHg. These findings suggest that the patient is experiencing acute respiratory failure secondary to his COPD exacerbation, likely due to increased air trapping and impaired gas exchange. The clinical team initiated non-invasive ventilation to improve oxygenation and decrease the work of breathing, while also adjusting his bronchodilator therapy to include nebulized treatments for more effective airway clearance.

This deterioration in the patient's respiratory status underscores the complexity of managing COPD exacerbations, requiring careful monitoring and timely interventions. The team is also considering further evaluation for potential secondary complications such as infection or cardiac involvement, given his history of hypertension and diabetes, which could be contributing to his current presentation. As the patient's condition evolves, the focus will be on optimizing respiratory support and assessing the effectiveness of the interventions in alleviating his symptoms and stabilizing his condition.

Section 2

As the afternoon progresses, the healthcare team notes a mixed response to the interventions implemented earlier. The non-invasive ventilation has helped improve the patient's oxygen saturation to 90%, yet he remains tachypneic with a respiratory rate of 26 breaths per minute. Despite the nebulized bronchodilator treatments, he continues to struggle with dyspnea and exhibits persistent use of accessory muscles. His heart rate remains elevated at 104 bpm, and he expresses ongoing fatigue and difficulty in breathing.

Given the minimal improvement and concern for potential secondary complications, the clinical team decides to conduct further investigations. A sputum culture is obtained to assess for any underlying infection that could be exacerbating the COPD flare. Blood tests reveal an elevated white blood cell count of 14,000/mm³, suggesting a possible infectious process. Considering his history of diabetes, the team also checks his blood glucose levels, which are noted to be 210 mg/dL, indicating poor glycemic control that might be contributing to his overall condition.

The patient's complex presentation calls for a multidisciplinary approach. The team deliberates on initiating a course of broad-spectrum antibiotics to target potential bacterial infection while closely monitoring blood glucose levels to prevent further metabolic derangement. As they continue to evaluate his response to the current treatment regimen, the focus remains on balancing the management of his COPD exacerbation with the possible infectious and metabolic complications. The priority is to stabilize his respiratory status and prevent further deterioration, ensuring all aspects of his care are addressed comprehensively.

Section 3

As the day progresses into the evening, the healthcare team observes a change in the patient's status, prompting a reassessment of his condition. The patient's respiratory rate has increased to 28 breaths per minute, indicating worsening tachypnea, and his oxygen saturation has slightly decreased to 88% despite the continued use of non-invasive ventilation. He is visibly more distressed, with pronounced use of accessory muscles and audible wheezing upon auscultation. His heart rate has climbed to 112 bpm, and he reports increased fatigue and anxiety about his breathing difficulties.

The results from the sputum culture reveal a significant growth of Haemophilus influenzae, confirming the presence of a bacterial infection likely contributing to the exacerbation of his COPD. In response, the clinical team promptly initiates a course of broad-spectrum antibiotics, adjusting the treatment strategy to address this new complication. Concurrently, his blood glucose levels remain elevated, fluctuating between 200-220 mg/dL, necessitating more rigorous glycemic control measures to prevent further metabolic complications.

In light of these developments, the healthcare team emphasizes the need for vigilant monitoring and reassessment of the patient's response to the revised treatment plan. They consult with the endocrinology team to optimize his diabetes management and consider the potential need for insulin therapy during this acute phase. The focus remains on stabilizing his respiratory status while addressing the infectious and metabolic components of his condition. This complex interplay of factors underscores the necessity for a coordinated, multidisciplinary approach to prevent further deterioration and improve the patient's overall prognosis.

Section 4

As the evening progresses into the night, the healthcare team notes a further change in the patient's status, signaling the need for another reassessment. The patient's respiratory distress has escalated; his respiratory rate is now 32 breaths per minute, with his oxygen saturation declining further to 85% despite the continuation of non-invasive ventilation. The pronounced use of accessory muscles persists, and the wheezing upon auscultation has become more pronounced, suggesting increasing airway obstruction. His heart rate has surged to 118 bpm, and he continues to express significant anxiety about his breathing, compounded by a sense of impending doom.

In light of these developments, the healthcare team orders a chest X-ray to rule out potential complications such as pneumonia or pneumothorax. The results reveal bilateral infiltrates suggestive of worsening infection or possible pulmonary edema, prompting the team to administer diuretics to address potential fluid overload. Additionally, arterial blood gas analysis shows a pH of 7.31, PaCO2 of 54 mmHg, and HCO3- of 28 mEq/L, indicating a state of acute on chronic respiratory acidosis, further complicating his COPD management.

The patient's blood glucose levels are still elevated, ranging between 210-230 mg/dL, despite adjustments in his oral hypoglycemic regimen. The endocrinology team recommends initiating a basal-bolus insulin regimen to achieve better glycemic control, which is critical to his overall recovery. As the team intensifies the treatment strategy, they emphasize the importance of continuous monitoring of the patient's respiratory and metabolic status, integrating insights from pulmonology, infectious disease, and endocrinology to devise an effective multidisciplinary plan of care. This coordinated approach aims to stabilize the patient's condition while preventing further exacerbations, paving the way for potential improvements in his clinical trajectory.

Section 5

As the night progresses, the healthcare team closely monitors the patient's response to the intensified treatment regimen. Initial improvements are observed in his respiratory status; his oxygen saturation rises to 89% with continued use of non-invasive ventilation, and his respiratory rate decreases slightly to 28 breaths per minute. However, the patient's heart rate remains elevated at 114 bpm, and his anxiety persists, albeit somewhat diminished due to reassurance and supportive care. The administration of diuretics appears to have alleviated some pulmonary congestion, as evidenced by reduced wheezing upon auscultation and improved breath sounds in the lower lung fields.

Despite these encouraging signs, the team is vigilant for any new complications. A repeat arterial blood gas analysis reveals a slight improvement in his acid-base status, with a pH of 7.34 and PaCO2 of 52 mmHg, indicating a partial respiratory compensation. However, the patient's electrolyte panel now shows a potassium level of 3.4 mEq/L, prompting the team to initiate potassium supplementation to prevent arrhythmias and support muscle function, particularly given his increased use of accessory respiratory muscles.

The patient's blood glucose levels begin to stabilize with the initiation of the basal-bolus insulin regimen, now ranging between 160-180 mg/dL, which is a positive development in his metabolic management. The endocrinology team remains engaged, advising regular glucose monitoring to fine-tune insulin dosing further. As the early morning hours approach, the interdisciplinary team continues to collaborate, ensuring that all aspects of the patient's complex condition are addressed. This coordinated effort is crucial as they strive to transition the patient towards a more stable respiratory and metabolic state, reducing the risk of further deterioration and setting the stage for his potential recovery.
