    Study Notes

    Basic Concepts

    • Respiratory systems have the main function of moving oxygen into body tissues and removing carbon dioxide
    • Aerobic exercise is not a type of respiration
    • Breathing, cellular respiration, and respiratory systems are all related to respiration

    Parts of the Respiratory System

    • The respiratory system includes trachea, bronchi, and alveoli, but not esophagus
    • Surfactant prevents alveolar walls from collapsing and sticking together
    • The entire respiratory tract is lined by pseudostratified ciliated columnar epithelium

    Pulmonary Infections

    • Pneumonia is characterized by infection in the lung parenchyma
    • Pneumonia can develop when defense mechanisms are impaired
    • Pneumonia can lead to complications such as abscess formation, pleural empyema, and organization & fibrosis

    Types of Pneumonia

    • Bronchopneumonia and lobar pneumonia are types of pneumonia based on anatomic classification
    • Viral pneumonia is not a type of pneumonia based on anatomic classification
    • Bronchopneumonia is often a complication of bronchiolitis or chronic bronchitis and is characterized by multiple foci of isolated acute consolidation

    Pneumonia Pathogens

    • Streptococcus pneumoniae is the most common cause of community-acquired acute pneumonia
    • Mycoplasma pneumoniae is commonly associated with community-acquired atypical pneumonia
    • Nosocomial pneumonia is often caused by methicillin-resistant Staphylococcus aureus

    Clinical Features and Outcomes

    • Pneumonia symptoms include high fever, shaking chills, and pleuritic chest pain
    • Complications of pneumonia include abscess formation, pleural empyema, and organization & fibrosis

    Community-Acquired Acute Pneumonias

    • The right middle lobe and lower lobe are frequently involved in community-acquired acute pneumonia
    • S. pneumoniae pneumonia evolves through four stages

    Bronchopneumonia

    • Bronchopneumonia often affects infants and elderly
    • Staphylococcus, Streptococcus, and Pneumococcus are common etiologies of bronchopneumonia
    • Rhinovirus is not a common etiology of bronchopneumonia

    Aspiration Pneumonia

    • Aspiration pneumonia is partly caused by chemical injury and bacterial infection
    • A common complication of aspiration pneumonia is abscess formation

    Lung Abscess

    • A lung abscess is characterized by necrosis of lung tissue
    • The most frequent cause of lung abscess is aspiration of infective material
    • Clinical features of lung abscess include copious foul-smelling purulent sputum, hemoptysis, and spiking fever

    Chronic Pneumonia

    • Mycobacterium tuberculosis is associated with chronic pneumonia
    • Granulomatous chronic pneumonia can be caused by Histoplasma capsulatum, Coccidioides immitis, and Blastomyces dermatitidis

    Pneumonia in Immunocompromised Hosts

    • Pneumonia in immunocompromised hosts can be caused by Cytomegalovirus, Pneumocystis jiroveci, and Mycobacterium avium-intracellulare

    Clinical Presentation

    • Typical community-acquired acute pneumonia presents with high fever and shaking chills
    • Atypical pneumonia typically presents with moderate amounts of sputum

    Diagnosis and Treatment

    • A common diagnostic feature of community-acquired acute pneumonia on a chest X-ray is consolidation of lung lobes
    • The primary treatment for bacterial pneumonia typically involves antibiotics
