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.
