Management of Pts w/ Chest & LRT Disorders Flashcards
- Refers to closure or collapse of alveoli
- Acute or chronic
*Acute is the most common (post-op/immobilized)
Excess secretions or mucous
- Chronic (e.g. tumor)
ATELECTASIS
*Occurs either in the community setting
or within the first 48 hours after
hospitalization or institutionalization.
Community-Acquired Pneumonia
- Inflammation of the lung
parenchyma - Caused by bacteria,
mycobacteria, fungi, and
viruses.
Pneumonia
pneumonia
low risk = w/ symptoms but no xray findings
moderate = may symptoms and findings sa xray
high risk = in pts with HPN, commatose, decrease sensorium (needs intubation)
–
Pneumonia in the Immunocompromised Host
common virus cause __
*Occurs with use of corticosteroids,
chemotherapy, nutritional depletion
* Antimicrobial agents, AIDS, genetic immune
disorders, mechanical ventilation
“Pneumocystis pneumonia”
*Onset of pneumonia symptoms more than 48
hours after admission in patients with no
evidence of infection at the time of admission.
- Ventilator-associated pneumonia is considered a
type of nosocomial pneumonia
*Impaired host defenses
Hospital-Acquired Pneumonia
Distribution of lung
involvement in bronchial
and lobar pneumonia
(left), patchy areas of
consolidation occur.
bronchopneumonia
- Refers to the pulmonary consequences resulting
from entry of endogenous or exogenous
substances into the lower airway - Most common is bacterial infection from aspiration
of bacteria that normally reside in the upper
airways - Gastric contents, exogenous chemical contents, or
irritating gases
Aspiration pneumonia
Distribution of lung
involvement in bronchial
and lobar pneumonia
(right), an entire lobe is
consolidated.
lobar pneumonia
- Aspiration of stomach contents into the lungs
*It can occur when the protective airway reflexes
are decreased or absent - Can result in tachycardia, dyspnea, central
cyanosis, hypertension, hypotension, and finally
death.
Aspiration
Vaccination against pneumococcal infection is
advised for the following:
* People 65 years of age or older
* People with functional or anatomic asplenia
* People living in environments or social settings in
which the risk of disease is high
* Immunocompromised people at high risk for
infection
Vaccination against pneumococcal infection is
advised for the following:
* People 65 years of age or older
* People with functional or anatomic asplenia
* People living in environments or social settings in
which the risk of disease is high
* Immunocompromised people at high risk for
infection
*Occurs unobserved
*If untreated, massive inhalation of gastric
contents develops in a period of several hours.
Silent aspiration
- Caused by a coronavirus
- Transmitted via respiratory droplets
- Close contact with a person who has been diagnosed with
the disease or a history of travel or residence in an area
with known cases - May also be spread when a person touches a surface
contaminated by the droplets and then touches his or
her mucous membranes.
Severe acute respiratory syndrome (SARS)
- Primarily affects the lung parenchyma
*It also may be transmitted to the meninges,
kidneys, bones, and lymph nodes. - Associated with poverty, malnutrition, overcrowding, substandard housing, and inadequate health care
Tuberculosis (TB)
treatment for SARS
oseltamivir / tami flue
transmission mode of TB
Airborne and droplets transmission
cause of tb
Mycobacterium tuberculosis
mantoux test
* A reaction of 5 mm or greater may be significant in people who are considered to be at risk
*An induration of 10 mm or greater is usually considered significant in people who have normal or
mildly impaired immunity.
