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.
