3. COPD Description Description –Chronic airflow obstruction Irreversible Irreversible –Chronic bronchitis and/or emphysema Incidence Incidence –13.5 million Americans have bronchitis –2 million Americans have emphysema –4 th leading cause of death –Death rate still rising –2 nd cause of disability in people > 65

4. COPD (cont.) Risk Factors Risk Factors –SMOKING –Age –Male gender –Air pollution –Occupational exposure –Respiratory infections –Familial & genetic factors

5. COPD (cont.) Pathophysiology Pathophysiology –Slow, progressive –Exacerbations  destructive changes –Usually have both chronic bronchitis and emphysema And frequently asthma And frequently asthma

6. Emphysema Patho Loss of lung elasticity Loss of lung elasticity Hyperinflation of the lungs Hyperinflation of the lungs Alveolar walls and small airways damaged Alveolar walls and small airways damaged –Airways narrow or collapse –Air trapping –Alveolar damage = poor gas exchange

7. Chronic Bronchitis Patho Inflammation caused by chronic irritation Inflammation caused by chronic irritation Cause vasodilation → congestion → edema → bronchospasm Cause vasodilation → congestion → edema → bronchospasm  mucous production  mucous production Thickened bronchial walls Thickened bronchial walls Narrowing of airways = poor gas exchange Narrowing of airways = poor gas exchange

8. Diagnostics ABG ABG Sputum C & S Sputum C & S CXR CXR CBC CBC Electrolytes Electrolytes Pulmonary function testing Pulmonary function testing Genetic testing Genetic testing

18. Collaborative Care Anxiety Anxiety –Inform patient of all aspects of care –Know what to do if ↑ in signs and symptoms –Support group –Complementary therapy

19. Collaborative Care Activity Intolerance Activity Intolerance –Pacing activities –Assess during activities for hypoxia –May need supplemental O2

20. Collaborative Care Potential For Infection (Respiratory) Potential For Infection (Respiratory) –Flu and Pneumonia vaccines yearly –Avoid large crowds

21. Home Care –Infection prevention –Breathing exercises –ADL assistance –Pulmonary rehab program –Dealing with chronic illness –May need a social worker

22. The Client with Pneumonia

23. Definition Excess fluid in lungs from inflammatory process Excess fluid in lungs from inflammatory process Types Types –Infectious → Viral or Bacterial Community acquired Community acquired Nosocomial Nosocomial –Inhalation of Irritants

24. Incidence 2 – 4 million cases in US yearly 2 – 4 million cases in US yearly 5 th leading cause of death 5 th leading cause of death  incidence  incidence –Elderly –LTC residents –Hospitalized clients –On ventilators

25. Incidence Continued More in fall and winter months More in fall and winter months Community acquired > nosocomial Community acquired > nosocomial

26. Risk Factors Community Acquired Community Acquired –Older Adult –No pneumococcal or flu vaccines –Chronic illness –Smoking –Alcohol –Exposure to viral or bacterial infections

27. Risk Factors Continued Nosocomial Nosocomial –Older adult –COPD –  LOC –Aspiration –Poor nutrition –Immune suppressed –Mechanical ventilation

28. Pathophysiology Organism invades airway Organism invades airway Multiples in alveoli Multiples in alveoli Inflammation in interstitial spaces, alveoli, and bronchioles Inflammation in interstitial spaces, alveoli, and bronchioles Fluids collect in alveoli Fluids collect in alveoli  gas exchange  gas exchange

29. Patho Continued Fibrin and RBCs move into alveoli Fibrin and RBCs move into alveoli –Causes stiffening =  compliance Alveoli collapse Alveoli collapse Consolidation occurs Consolidation occurs Infection spreads to other lung areas Infection spreads to other lung areas

30. Sites of Pneumonia Lobar pneumonia Lobar pneumonia –Segment or lobe of the lung Bronchopneumonia Bronchopneumonia –In bronchus and bronchioles

31. Diagnostics ABGs ABGs CBC, Lytes CBC, Lytes –May need HIV testing Sputum gram stain and C & S Sputum gram stain and C & S CXR CXR Bronchoscopy Bronchoscopy

32. Manifestations General Appearance General Appearance –Flushed fever fever –Anxious –Muscle weakness –Headache –Chills –Poor appetite

33. Manifestations Respiratory Respiratory –Productive cough –Tachypnea, orthopneic –Use of accessory muscles –Crackles, wheezing –Pleuritic pain
