Q

What is the pathophysiology of pneumonia?

A
  1. S. Pneumonia (Bacteria) aspirated into the lungs
  2. Inflammatory response is initiated
  3. Alveolar edema & exudate formation
  4. Bronchioles & alveoli fill c serous exudate, blood, fibrin & bacteria.
  5. Lung tissue consolidates (to be made solid)

Q

How does pneumonia affect the patient?

A
  1. Affects the ability to ventilate properly (Inhalation & exhalation).
  2. Affects the ability of respiration (The exchange of oxygen & carbon dioxide).
  3. Affects the ability to maintain a patent airway.

Q

What is Bronchopneumonia?

A
  1. Affects dependent portions of the lung tissue
  2. Patchy consolidation is visible bc exudate remain in the bronchi
  3. There is less edema & congestion than lobar

Q

What is Interstitial Pneumonia?

A
  1. The inflammatory response involves the interstitium (alveolar walls & tissue)
  2. Does not show significant exudate
  3. Protein rich hyaline membranes line alveoli which interferes c gas exchange.

Q

What is Miliary Pneumonia?

A
  1. The spread of the pathogen to the lungs via the blood stream.
  2. Discrete inflammatory lesions are visible.
  3. Seen mainly in severely immunocompromised patients.
  4. Seen in TB patients.
  5. Bc of poor immune response, damage to pleural tissue may be significant.

Q

What are some complications from pneumonia?

A
  1. Atelectasis- Alveolar collapse
  2. Pleuritis- Inflammation of pleural-lining surrounding lungs.
  3. Pleural Effusion- Accumulation of excess fluid in pleural cavity.
  4. Lung Abscess- Local area of necrosis & pus formation within lungs.
    A. Sputum foul smelling
    Rupture into larger airway causes production of copious amounts of purulent sputum.
  5. Empyema- Accumulation of purulent exudate in pleural cavity.

Q

How do Bacterial Pathogen cause Pneumonia?

A
  1. Circulate through the bloodstream to lungs where they damage pleural cells.
  2. The bacteria is distributed evenly throughout 1-2 lobes of a single lung called (UNILATERAL LOBAL PNEUMONIA).

Q

How do Viruses cause Pneumonia?

A
  1. A virus will enter from the upper respiratory tract, infiltrating the alveoli nearest the bronchi.
  2. Invades cells, replicates, then bursts out killing cells & sending out cellular debris.
  3. This bursting causes rapid invasion of adjacent area. Viewed on x-ray as bronchopneumonia.

Q

How does Aspiration Pneumonia occur?

A
  1. Aspiration of food, emesis, gastric reflux causes chemical injury & inflammatory response.
  2. This lowers pH, which causes more inflammation.
  3. This also allows for further bacterial invasion.

Q

What are Risk Factors for Pneumonia?

A
  1. Cigarette Smoking
    A. Injures airway tissue
    B. Decreases cilia actions
    C. The Chemicals Numb Coughing Reflex
  2. Alcohol
    A. Interferes c actions of Macrophages
  3. Drug Abuse
    A. Higher risk for infections @ injection sites, spreading through blood stream to lungs.
  4. Age >65
  5. Chronic Cardiac, Respiratory, DM Diseases.
17
Q

What are some Opportunistic Risk Factors for Pneumonia?

A
  1. Significantly in immunocompromised ppl. such as HIV/AIDS & Cancer pt.’s on chemotherapy.
  2. Seen on X-ray as patchy throughout the lungs.
  3. Alveoli thicken bc of edema & fill c protein rich fluid.
  4. Has an abrupt onset.
18
Q

A

Mid-Winter

Smoking is a Major Risk Factor as well.
