    Study Notes

    COPD (Chronic Obstructive Pulmonary Disease)

    • Definition: A slow, progressive respiratory disease characterized by airflow obstruction.
    • Types: Chronic bronchitis and Emphysema.
    • Prevalence: Fourth leading cause of death in the US.
    • Preventable: While preventable and treatable, not fully reversible.
    • Pathophysiology: progressive, associated with inflammatory response to noxious particles or gases, resulting in tissue damage, airway narrowing, and reduced elasticity.

    COPD Classification

    • GOLD 1 (Mild): FEV1 ≥ 80% predicted
    • GOLD 2 (Moderate): 50% ≤ FEV1 < 80% predicted
    • GOLD 3 (Severe): 30% ≤ FEV1 < 50% predicted
    • GOLD 4 (Very Severe): FEV1 < 30% predicted

    What is COPD?

    • Patient Profile: Typically patients greater than 45 years old.
    • Symptoms: Respiratory symptoms include cough and shortness of breath, post-bronchodilator FEV1/FVC ratio <0.7.
    • Etiology: History of smoking and/or exposure to other pollutants.
    • Diagnosis: A post-bronchodilator ratio of FEV1/FVC <0.7 (or lower limit of normal), and a low FEV1/FVC percentage.

    Pulmonary Emphysema

    • Definition: A progressive lung disease, a form of COPD, primarily affecting the airspaces.
    • Characteristics: Destruction of alveoli, leading to impaired gas exchange
    • Types: Centriacinar, Panacinar, Paraseptal

    Pulmonary Embolism (PE)

    • Definition: Blood clot obstructs pulmonary artery.
    • Origin: Usually originates in deep veins of lower extremities (DVT).
    • Etiology: Combination of factors (Virchow's triad), including hypercoagulability, venous stasis, and endothelial injury.

    Acute Respiratory Distress Syndrome (ARDS)

    • Definition: Serious lung condition causing low blood oxygen; fluid buildup in lung's alveoli, surfactant breakdown.
    • Key characteristics: Life-threatening, poor oxygenation, pulmonary infiltrates, acute onset.
    • Risk Factors: Pulmonary infections (e.g., COVID-19), pulmonary aspiration, extra-pulmonary sources (sepsis, trauma), pancreatitis, drug overdose, fat embolism; advanced age, female gender, smoking.
    • Phases: First (alveolar-capillary damage), Proliferative, Final Fibrotic (scarring)

    Respiratory Failure

    • Definition: Respiratory system fails to supply, oxygen (hypoxemia) or eliminate sufficient carbon dioxide (hypercapnea) causing impaired metabolism
    • Types: Hypoxic or Ventilatory failure
    • Etiology: CNS depression, inadequate neuromuscular ability to sustain breathing, and excessive respiratory system load; airway pathology (e.g., foreign bodies, tumors); lung conditions (e.g., pulmonary edema, ARDS).

    Pneumonia

    • Definition: Lung infection, often caused by viruses or bacteria.
    • Transmission: Can be spread by viruses and bacteria in the air, via saliva, or through other direct contact.
    • Types: Bacterial, fungal, mycobacterial, viral, community-acquired (CAP), hospital-acquired (HAP), and ventilator-associated (VAP). Aspiration.

    Pulmonary Hypertension

    • Definition: Increased blood pressure in the pulmonary arteries.
    • Classification: Grouped into 5 classifications based on underlying causes.
    • Symptoms: Shortness of breath, chest pain, fainting, fatigue and tiredness.

    Ischemic Heart Disease

    • Etiology: Atherosclerosis (plaque buildup) in the coronary arteries.
    • Symptoms: Chest pain (angina), may or may not radiate and accompany other symptoms including shortness of breath, anxiety, nausea, and sweating.
    • Possible complications: Heart attack and other severe cardiac conditions.
