Study Notes
Pneumonia Overview
- Pneumonia is lung inflammation from infection.
- Lungs have lobes, air travels through trachea, bronchi, bronchioles to alveoli.
- Alveoli inflate during inhalation, deflate during exhalation.
- Capillaries surround alveoli, oxygen enters, carbon dioxide exits.
- Infections caused by bacteria, viruses, fungi, or parasites.
- Airways trap germs in mucus, cilia push out (coughing).
- Immune cells fight germs; weakened immunity allows multiplication.
- Inflammation fills alveoli with fluid, hindering oxygen uptake.
Types of Pneumonia
- Lobar pneumonia: one lung lobe affected.
- Bronchopneumonia: multiple lung areas affected.
Symptoms of Pneumonia
- Difficulty breathing
- Chest pain
- Coughing
- Fever and chills
- Confusion
- Headache
- Muscle pain
- Fatigue
Complications of Pneumonia
- Respiratory failure (ventilator needed)
- Bacteremia (bacteria in bloodstream)
- Lung abscess (collection of fluid and pus)
- Empyema (pus around the lung)
Treatments for Pneumonia
- Antibiotics (bacterial/parasitic pneumonia)
- Antiviral drugs (viral pneumonia, like flu)
- Antifungal medication (fungal pneumonia)
- Rest, fluids
- Over-the-counter remedies (fever, aches)
- Hospitalization with IV antibiotics and oxygen (severe cases)
