Study Notes
Chronic Obstructive Pulmonary Disease (COPD)
- PINK PUFFER: Characteristic of a thin, cathetic individual with significant shortness of breath but well-oxygenated blood due to reduced ventilation and perfusion.
- Reduced elastin fibers in lungs lead to structural weaknesses in alveoli and airways, causing collapses during expiration and air trapping.
- Defined as a preventable and treatable condition with chronic dyspnea and expiratory airflow limitation.
Pathophysiology
- Chronic inflammation in airways and lung tissue results in airway narrowing and increased mucus production influenced by goblet cell proliferation and submucosal gland enlargement.
- Loss of alveolar attachments and elastic recoil contributes to complications like abnormal distention of airspaces.
- Thickening of pulmonary blood vessel linings due to prolonged inflammation.
Complications
- Major life-threatening complications include respiratory failure and respiratory insufficiency.
Assessment and Diagnostic Findings
- Health history is crucial in evaluating COPD.
- Diagnostic tools include:
- Spirometry
- Arterial blood gases (ABG)
- Chest X-ray
- CT scan
- Bronchogram
- Lung scan
- Complete blood count (CBC)
- Blood chemistry
- Sputum cultures
- Cytology exams
- Electrocardiograms (ECGs)
- Stress tests
Epidemiology
- COPD ranks as the fourth leading cause of mortality in the U.S.
- Higher mortality rates observed in women.
Medical Management
- Bronchodilators and corticosteroids are key therapeutic agents.
- Understanding the disease process and prognosis is essential for effective management.
- Similarities with Acute Respiratory Distress Syndrome (ARDS) include swelling and fluid accumulation in lung tissues.
Nursing Priorities
- Ensuring airway patency and facilitating gas exchange is critical.
- Enhance nutritional intake to support recovery.
- Aim to prevent complications and slow the disease's progression.
- Provide comprehensive information about the illness and treatment options.
Causes of Lung Injury
- Direct injury: trauma, inhalation of harmful substances, burns.
- Indirect injury: severe infections, massive blood transfusions, pneumonia, pancreatitis, substance overdose.
Symptoms of ARDS
- Shortness of breath, fast and labored respiration, cyanosis, rapid pulse, and bluish skin.
- Excessive sputum and nasal flaring may also be evident.
Management of Breathing Patterns
- Dyspnea and the use of accessory muscles indicate an ineffective breathing pattern related to alveolar impairment, decreased lung expansion, and lung fibrosis.
Surgical Management
- Surgical interventions include embolectomy to remove emboli, either through open surgery or transvenous catheter techniques.
- Interrupting the vena cava can prevent dislodgment of thrombi and maintain blood flow.
Nursing Management
- Monitor hypoxemia, pain management, and emotional support throughout recovery.
- Encourage ambulation and leg exercises to prevent venous stasis.
- Regular monitoring of anticoagulant therapy and adherence to prescribed management plans is essential.
- Track INR (1 to 2) and PTT (30 to 45 seconds) for anticoagulant effectiveness.
