Study Notes
COPD and Emphysema
- COPD: Chronic Obstructive Pulmonary Disease
- Emphysema: Gradual damage to lung tissue, destruction of alveoli
- Blue Bloaters: Cyanosis due to low oxygen levels in the blood
- Pink Puffers: Compensatory puffing or prolonged expiration due to CO2 trapping
- Barrel Chest: Increased anterior/posterior diameter of the chest
- Clubbing of fingers: Late sign of COPD
- Signs and symptoms: Hypoxia (restlessness), dyspnea, barrel chest, diminished breath sounds, fatigue, non-productive cough, hyperresonance upon percussion.
Nursing Diagnosis: Ineffective Airway Clearance
- Increased mucus
- Thick, tenacious white or gray sputum
- Productive cough
Medical Management
- Bronchodilators: Beta agonists (albuterol, salbutamol, isoproterenol)
Nursing Management
- Promote Airway: increase fluid to loosen secretions, coughing to expel secretions, suctioning as needed, chest percussion therapy (CPT), postural drainage
- Promote Breathing: Positioning (orthopneic position), pursed lip breathing (inhale through nose, exhale through mouth twice as long), mechanical ventilation (non-invasive, IPPB)
- Health Teaching: Rest, avoid smoking, infection prevention (handwashing, avoid crowded places), diet (increase calories and protein, decrease carbohydrates)
Atelectasis
- Collapse of one or more parts of the lung
- Affects alveoli, the tiny air sacs in the lungs
Types of Atelectasis
- Compressive atelectasis: Fluid, air, blood, or tumors push on the lung causing collapse.
- Resorptive atelectasis: Oxygen and carbon dioxide move into the bloodstream and no new air moves into the alveoli, causing them to collapse. Commonly occurs due to surgery requiring anesthesia.
- Obstructive atelectasis: Also known as resorptive atelectasis, occurs when something like mucus, a tumor, or an inhaled object blocks the inside of the lungs.
- Contraction atelectasis: Lung scarring (fibrosis) causes the alveoli to not open properly.
Clinical Manifestation of Atelectasis
- Dyspnea (shortness of breath), cough, sputum production, tachycardia, tachypnea, pleural pain, central cyanosis, orthopnea
- In acute atelectasis involving a large amount of lung tissue (lobar atelectasis), marked respiratory distress.
- In chronic atelectasis, similar symptoms as acute atelectasis, but alveolar collapse predisposes patients to infection distal to the obstruction.
Pneumonia
- Inflammation of the lungs, often caused by infection.
- Aspiration pneumonia: Entry of exogenous or endogenous substances into the lower airway.
- Common pathogens: Anaerobes, Staphylococcus aureus, Streptococcus species, and Gram-negative bacilli.
- Other aspirated substances: Gastric contents, exogenous chemical contents, or irritating gasses.
- Risk factors: Heart failure, diabetes, alcoholism, COPD, AIDS.
Pneumonia in Immunosuppressed Hosts
- Pneumonia can occur with the use of corticosteroids, other immunosuppressive agents, chemotherapy, nutritional depletion, broad-spectrum antimicrobials, AIDS, genetic immune disorders, and long-term advanced life support technology.
Passageway of Respiration
- Mouth/nose > pharynx > larynx > trachea > lungs > bronchus > bronchioles > alveoli.
- Alveoli are the dead end of the inhaled air and are close to the blood.
- Oxygen enters the blood from alveoli and carbon dioxide moves from the blood to the alveoli to be exhaled.
