Study Notes
Chronic Obstructive Pulmonary Disease (COPD)
- Affects 15 million in the U.S. and 900,000 in Canada.
- 4th leading cause of morbidity and mortality in the U.S.
- Defined as a collection of lower airway disorders hindering airflow and gas exchange.
- Includes two main conditions:
- Emphysema: Destruction of lung elastic tissue reduces recoil capability, causing hyperinflation and air trapping.
- Chronic Bronchitis: Inflammation of bronchi/bronchioles due to irritants like cigarette smoke, leading to mucus overproduction and airway obstruction.
Pathophysiology of COPD
- Alveolar damage results in gas exchange compromise; leads to CO2 retention and respiratory acidosis.
- Patients experience increased work of breathing and sensations of "air hunger."
Risk Factors for COPD
- Cigarette smoking is the primary risk factor.
- Additional risk factors include alpha1-antitrypsin deficiency and prior asthma.
Complications of COPD
- Potential complications include:
- Hypoxemia
- Respiratory acidosis
- Respiratory infections
- Cardiac failure (cor pulmonale)
- Dysrhythmias
- Respiratory failure
COPD Assessment and Management
- Importance of thorough medical history and physical assessment:
- Includes smoking history, breathing issues, activity levels, and weight gain.
- Laboratory assessments focus on ABGs and pulse oximetry to monitor oxygen saturation (target: 88-92%).
Weight Management and Anxiety in COPD Patients
- Strategies to prevent weight loss include frequent small meals and high-calorie food options.
- Anxiety management techniques, such as counseling, hypnosis, and relaxation techniques, are essential.
Prevention and Recovery
- Prioritize smoking cessation and manage infections, including pneumonia.
- Focus on improving endurance to assist with activities of daily living.
Overview of Asthma
- Can occur at any age, with a peak incidence between 10-17 years.
- 8.3% of U.S. children are affected, with higher rates in urban areas and African American populations.
Asthma Pathophysiology
- Characterized by reversible obstructive airway disease due to inflammation, bronchospasm, and mucus accumulation.
- Assess for related conditions like allergic rhinitis and sinusitis.
Asthma Symptom Assessment
- Key indicators of asthma control:
- Frequency of daytime symptoms (wheezing, dyspnea, coughing).
- Nighttime symptoms and reliance on rescue medications.
- Activity limitation due to asthma symptoms.
Asthma Therapy Goals
- Objectives focus on improving airflow and gas exchange through recognition of symptoms, avoidance of triggers, proper medication administration, and patient education.
Asthma Medications
- Rescue medications include inhaled short-acting beta agonists (e.g., Albuterol) and anticholinergics.
- Control medications (long-term) include inhaled corticosteroids, long-acting beta agonists, and leukotriene inhibitors.
Emergency Asthma Treatment Indicators
- Signs indicating the need for urgent care include worsening symptoms unresponsive to bronchodilators, trouble breathing, or signs of cyanosis (blue lips or nails).
Status Asthmaticus
- A life-threatening severe asthma episode that can lead to pneumothorax and respiratory/cardiac arrest; requires emergency treatment.
Environmental Modifications for Asthma Patients
- Implement strategies to minimize allergens, such as using dust-proof covers, cleaning regularly, and maintaining proper household humidity levels.
Chronic Obstructive Pulmonary Disease (COPD) Overview
- Affects approximately 15 million in the U.S. and 900,000 in Canada.
- 4th leading cause of morbidity and mortality in the U.S.
- Defined as a collection of lower airway disorders that interfere with airflow and gas exchange.
Emphysema
- Characterized by destruction of lung elastic tissue, reducing recoil ability and causing hyperinflation.
- Results in air trapping, increased work of breathing, sensation of "air hunger," and decreased gas exchange leading to CO2 retention and respiratory acidosis.
Chronic Bronchitis
- Inflammation of bronchi and bronchioles primarily caused by irritants like cigarette smoke.
- Triggers inflammation, vasodilation, congestion, and bronchospasm.
- Thickened bronchial walls and excessive mucus impede airflow, increasing infection risks.
Risk Factors
- Primary risk factor: Cigarette smoking.
- Other factors include alpha1-antitrypsin deficiency and asthma.
Complications of COPD
- Hypoxemia and acidosis.
- Respiratory infections.
- Cardiac failure, specifically cor pulmonale.
- Dysrhythmias and respiratory failure.
Assessment Techniques
- Physical assessment includes recognition of respiratory and cardiac changes.
- Psychosocial assessments focus on the individual’s emotional well-being.
- Laboratory assessments such as arterial blood gases (ABG’s) aid in monitoring hypoxemia and hypercapnia.
COPD Management Strategies
- Oxygen administration requires careful monitoring, aiming for O2 saturation of 88-92%.
- Weight management through small, high-calorie meals and strategies to reduce dyspnea during eating, such as pursed-lip breathing.
- Support for anxiety through counseling, relaxation techniques, and developing a clear management plan.
Health Promotion and Maintenance
- Smoking cessation is vital for prevention of further disease progression.
- Home care management and self-management education regarding drug therapies and breathing techniques are essential.
- Goals include maintaining baseline gas exchange, achieving effective breathing patterns, and avoiding respiratory infections.
Evaluation of Outcomes
- Assess progress toward maintaining a body weight within 10% of ideal weight and increased acceptable activity levels.
- Reduction in anxiety levels and implementation of strategies to prevent serious respiratory infections.
NCLEX Style Questions
- Examples provided assess understanding of patient statements that indicate worsening dyspnea, proper chest tube care, and priority actions based on peak flowmeter readings.
Conclusion
- Management of COPD requires a multi-faceted approach involving risk assessment, careful monitoring, lifestyle modifications, and coordination of care to improve patient outcomes.
