2. Definition:
 An inflammatory
process in lung

interstitial and
alveolar fluid.

9. Path-physiology:
Offending organism/agent.
Inflammatory pulmonary response.
Lose defense mechanisms of the lungs.
Allow organisms to penetrate the sterile LRT.
Develop inflammation.
6/6/2018 9www.drjayeshpatidar.blogspot.com

10. Disruption of the mechanical defenses
(cough & ciliary motility)
Colonization of the lungs.
Inflamed & fluid-filled alveolar sacs.
Alveolar exudates tends to consolidate.
Difficult to expectorate.

6/6/2018 24www.drjayeshpatidar.blogspot.com

25. Nursing management:
Ineffective airway clearance R/t excessive
secretions & weak cough.
Ineffective breathing pattern R/t tachypnea.
Activity intolerance R/t decreased oxygen
levels for metabolic demands.
Deficient fluid volume R/t fever, diaphoresis,
& mouth breathing.
Imbalanced nutrition: less than body
requirements R/t dyspnea.
Pain R/t frequent coughing.
6/6/2018 25www.drjayeshpatidar.blogspot.com

26. Cont….

breathing & frequent cough.

27. Possible complications:
 Respiratory failure.
 Empyema or lung abscesses. These are
infrequent, but serious, complications of
pneumonia. They occur when pockets of pus
form inside or around the lung. These may
sometimes need to be drained with surgery.
 Sepsis, a condition in which there is
uncontrolled swelling (inflammation) in the
body, which may lead to organ failure
 Acute respiratory distress syndrome (ARDS),
a severe form of respiratory failure

28. Pneumonia At A Glance:
Pneumonia is a lung infection that can be caused by
different types of microorganisms, including bacteria,
viruses, and fungi.
Symptoms of pneumonia include cough with sputum
production, fever, and sharp chest pain on inspiration
(breathing in).
Pneumonia is suspected when a doctor hears abnormal
sounds in the chest, and the diagnosis is confirmed by a
chest x-ray.
Bacteria causing pneumonia can be identified by sputum
culture.
