when both lungs are affected, it is known as bilateral or double pneumonia |
|
What is bronchopneumonia?
|
begins in the terminal bronchioles, which becomes clogged with mucopurulent exudate to form consolidated patches in nearby lobules, also called lobular pneumonia
|
|
What is interstitial pneumonia?
|
the inflammatory process is more or less confined within the alveolar walls (interstitium) and theh peribronchial and interlobular tissues
|
|
Although the morphologic classification is typically used, the most useful classification of pneumonia is based on?
|
etiologic agent
ex: viral bacterial mycoplasmal aspiration of foreign substances |
|
What else might cause pneumonia?
|
histomycosis
coccidioidomycosis other fungi identified from clinical history, age, physical exam, radiography, lab exam |

Which pneumonias occur most frequently, viral or bacterial?
|
viral...seen in children of all ages and often associated with viral URIs
|
|
What viruses cause pneumonia?
|
RSV in infants
parainfluenza influenza adenovirus in older children |
|
Viral infections of respiratory tract render the affected child more susceptible to?
symptomatic and includes measures to promote oxygenation and comfort, such as oxygen administration with cool mist, chest physiotherapy and postural drainage, antipyretics for fever management, fluid intake, and family support |
secondary bacterial invasion, esp. when there is denuded bronchial mucosa....
what is the treatment for this? |
|
What is primary atypical pneumonia?
|
Mycoplasma pneumoniae is the most common cause of pneumonia in children between ages 5 and 12 years...occurs fall and winter...7-10 day illness...no hospitalization

unproductive to productive
with whitish sputum tachypnea breath sounds-rhonchi or fine crackles dullness with percussion chest pain retractions nasal flaring pallor to cyanosis (depends on severity) chest x-ray film - diffuse or patchy infiltration with peribronchial distribution behavior - irritable, restless, lethargic GI--anorexia, vomiting, diarrhea, abdominal pain |
|
<What is lung parenchyma?
|
lung alveoli and lower bronchioles
general definition: essential parts of an organ that are concerned with its function in contradistinction to its framework |

|
<What are 2 classifications of pneumonia?
|
community acquired
hospital acquired |
|
<Hospital adquired pneumonia as what percentage mortality rate and it's higher for patients with complications...that's why it's important for patient to continue deep breathing, keep turning, particularly after anesthetic because mortality from hospitalized pneumonia is very high
