Unit 6 - Pneumonia Flashcards
Pneumonia ->
inflammation of lung parenchyma
3 ways organisms enter lungs
- aspiration
- inhaled
- through bloodstream from infection in body
4 patterns pneumonia develops
- lobar pneumonia
- bronchopneumonia
- interstitial pneumonia
- miliary pneumoni4.
Pathological process varies according to infective organism:
Bacterial pathogens
unilateral lobar pneumonia
Pathological process varies according to infective organism:
Viruses
scattered, patchy, bronchopneumonia
Pathological process varies according to infective organism:
Aspiration
- chemical injury leading to inflammatory response
- open to bacterial invasion
Bronchopneumonia -> _____ onset
insidious
_____ disease occurs sporadically and in outbreaks, such as the one that occurred at an American Legion convention in 1976, when the disease was first recognized. Contaminated water-cooled air-conditioning systems and other water sources have been implicated in its spread. Smokers, older adults, and people with chronic diseases or impaired immune defenses are most susceptible to this disease
Legionnaires
Acute bacterial pneumonia
pathogenesis of pneumococcal pneumonia
Describe pathogenesis of pneumococcal pneumonia
bacteria reside in upper respiratory tract
Legionnaire disease
bronchopneumonia
Primary atypical pneumonia
mycoplasma pneumoniae (“walking pneumonia”)
Common organisms of viral pneumonia
- influenza
- adenovirus
Onset of Pneumococcal or lobar pneumonia
abrupt
Onset of bronchopneumonia
gradual
Onset of Legionnaire disease
gradual
