Study Notes
Chronic Obstructive Pulmonary Disease (COPD)
- Airflow is limited to and from the lungs, causing shortness of breath.
- Causes:
- Smoking
- Occupational exposures (e.g. coal mining, gold mining, cotton textile industry)
- Air pollution
- Sudden airway constriction in response to inhaled irritants
- Genetics (e.g., Alpha 1-antitrypsin deficiency)
Emphysema
- Airspaces in the lungs enlarge, causing hyperinflation of the lungs and increased total lung capacity.
Pulmonary Tuberculosis
-
Risk Factors:
- Children under 5 years old
- Drinking unpasteurized milk from infected cows
- Homeless individuals or those from lower socioeconomic groups, minorities, or refugee groups
- Frequent contact with untreated or undiagnosed individuals
- Crowded living environments (e.g., long-term care facilities, prisons, mental health facilities)
- Older individuals
- Malnutrition, infection, immune dysfunction, HIV infection, or immunosuppression due to medication therapy
- Alcohol abuse and IV drug users
-
Transmission:
- Via airborne route by droplet infection.
-
Pathophysiology:
- Droplets enter the lungs, forming tubercle lesions.
- The body encapsulates the tubercle, leaving a scar.
Acute Hypoxemic Respiratory Failure
- The main therapeutic goal in acute hypoxemic respiratory failure is to ensure adequate oxygenation of vital organs, usually achieved through mechanical ventilation.
