Pneumonia Flashcards
pneumonia (restrictive disease) define
Infection of the lower respiratory tract Responsible for more disease and death than any other infection Community-acquired pneumonia Streptococcus pneumoniae Health care–associated pneumonia Hospital-acquired (nosocomial) pneumonia Ventilator-associated pneumonia Routes of infection Aspiration – foreign object swallowed into the airways Inhalation Endotracheal tubes and suctioning
Pneumoccocal pneumonia
ALI (acute lung injury), resulting in inflammatory cytokines and cells, causes alveolar edema.
Edema creates a medium for the multiplication of bacteria and aids in the spread of infection into adjacent portions of the lung.
Involved lobe undergoes consolidation.
Viral pneumonia
seasonal; usually mild and self-limiting.
Can set the stage for a secondary bacterial infection.
Provides an ideal environment for bacterial growth and by damaging ciliated epithelial cells, which normally prevent pathogens from reaching the lower airways.
Most common form: Influenza
PNEUMONIA: treatment
Establishment of adequate ventilation and oxygenation
May require mechanical ventilation
Adequate hydration
Good pulmonary hygiene (e.g., deep breathing, coughing, chest physical therapy)
Bacterial pneumonia: Antibiotics
Viral pneumonia: Supportive therapy alone, unless secondary bacterial infection is present
Severe cases: Antiviral medications and/or antifungal, multiple drugs
