2. INTRODUCTION
It is an inflammatory condition of the lung that is
caused by a microbial agent.
“Pneumonitis” is a general term that describes an
inflammatory process in the lung tissue that may
predispose a patient to or place a patient at risk for
microbial invasion.
It is the leading cause of death from the infectious
disease.
3. DEFINITION
“An inflammation of the lung
parenchyma (the respiratory bronchioles
and the alveoli) is known as Pneumonia”.
Pneumonia is mainly caused by
microorganisms which enter the lower
respiratory system and cause infection.
The microorganism includes bacteria,
mycobacteria, mycoplasma, fungi,
parasites, and viruses.
4. EPIDEMIOLOGY
Common illness affecting approximately 450 million
people a year occurring in all part of the world, and 4
million death yearly .
Rates are greater in children less than five years and
adult older than 75 years.
It occurs five times more in the developing world than
in the developed world.
5. EPIDEMIOLOGY cont...
It is the eighth leading cause of death in United States ,
resulting in almost 70,000 deaths per year. In persons
65 years of age and older, it is the fifth leading cause of
death.
In India it is the single largest cause of death in
children, resulting in nearly 120 million cases a year.
6. CLASSIFICATION
1. According to the causative organisms
(a) Bacterial :-
Pneumococcal pneumonia caused by Streptococcus pneumonia**
Staphylococcal pneumonia caused by Staphylococcus aureus
Influenzal pneumonia caused by Haemophilus influenza
Gram-negative bacterial pneumonia caused by Klebsiella
pneumonia
Anaerobic bacterial pneumonia caused by normal oral flora.
7. CLASSIFICATION contd…
(b) Viral :-
Rhinovirus, coronaviruses, influenza virus, respiratory sncytial virus(RSV),
adenovirus and parainfluenza.
Herpes simplex virus rarely causes pneumonia in newborns, persons with
cancer, transplant recipients, and people with significant burns.
People following organ transplantation or immunocompromised present
high rates of cytomegalovirus pneumonia.

Fungal pneumonia caused by histoplasmosis , blastomycosis,
coccidioidomycosis, aspergillosis, candidiasis.
8. CLASSIFICATION cont…
(d) Parasitic :-
Parasitic pneumonia (caused by protozoa, nematodes,
platyhelminthes); common organism is Pneumocystis
(carinii) firoveci

10. CLASSIFICATION cont…
3. According to the areas of the lung involved/affected
Lobar pneumonia
Multilobar pneumonia
Bronchial pneumonia
Interstitial pneumonia
Alveolar (acinar) pneumonia
Necrotizing pneumonia
Segmental pneumonia
11. CLASSIFICATION cont…
4. According to the cause
Bronchiolitis obliterans organizing pneumonia (BOOP)/
cryptogenic organizing pneumonitis (COP).
Eosinophilic pneumonia : occur in response to infection with
parasite.
Chemical pneumonia
Aspiration pneumonia
Dust pneumonia
Bilateral pneumonia.
12. ETIOLOY
There are many causes of pneumonia including
bacteria, viruses, mycoplasmas, fungal agents and
protozoa. It may also result from inhalation of toxic
or caustic chemicals, smoke, dusts or gases or
aspiration of food, fluids, or vomitus. Pneumonia may
complicate to chronic illnesses.
13. RISK FACTORS
Age 60 or older
Smoking
Air pollution
Altered consciousness : Alcoholism, head injury, anaesthesia,
drug overdose
Tracheal intubation
Upper Respiratory Tract Infection
Chronic Disease : Chronic lung disease, Diabetes mellitus,
heart disease, cancer
14. RISK FACTORS contd…
Immunosuppression.
Malnutrition.
Inhalation of noxious substances.
Prolonged Bed rest and immobility
Aspiration of fluid, liquid, foreign or gastric content.
Prolonged hospital stay.
Residence in institutional areas/setting where transmission is
prone.
Fatigue
15. PATHOPHYSIOLOGY
Infectious agent, Foreign substance, blood borne organisms
that enter the blood circulation or Aspiration of gastric content
Mucosal edema of
alveolar membrane occur
The alveoli fills with
exudates
Cause inflammation of pulmonary tissue affecting both
ventilation and diffusion
16. PATHOPHYSIOLOGY
interferes with the
diffusion of oxygen and
carbon dioxide
causing occlution of
alveoli resulting in
decrease alveolar oxygen
tension
Hypoxia occur with retention of
carbon dioxide, Shortness of
breath, Fatigue ,Crackles in
lungs Or decrease Breath
sounds
27. PROGNOSIS
With treatment, most types of bacterial pneumonia
will stabilize in 3–6 days. It often takes a few
weeks before most symptoms resolved. In persons
requiring hospitalization, mortality may be as high
as 10%, and in those requiring intensive care it may
reach 30–50%.
28. NURSING MANAGEMENT Nursing Assessment
Take a careful history to help establish etiologic diagnosis.
Assess the elderly patient for unusual behavior, altered mental
status, dehydration, excessive fatigue, and concomitant heart
failure.
Observe for anxious, flushed appearance, shallow respirations,
splinting of affected side, confusion, disorientation.
Auscultate for crackles overlying affected region, and for
bronchial breath sounds when consolidation (filling of airspaces
with exudate) is present.
29. NURSING MANAGEMENT cont…
NURSING DIAGNOSIS AND INTERVENTIONS
1. Impaired gas exchange related to inflammatory pulmonary
infection evidenced by presence of retained secretions,
Changes in respiratory rate diminished/adventitious breath
sounds, dyspnea, cyanosis Ineffective cough
INTERVENTION
Assess rate, depth of respirations and chest movement.
Auscultate lung fields.
Elevate head of bed.
Assist and demonstrate client with frequent deep-breathing
exercises, splinting the chest and coughing.

Force fluids to at least 2500 mL per day, unless
contraindicated, as in HF
30. NURSING MANAGEMENT cont…
Assist with and monitor effects of nebulizer treatments and
other respiratory physiotherapy, such as incentive spirometer,
percussion, and postural drainage.
Administer medications, as indicated, for example, mucolytics,
expectorants, bronchodilators, and analgesics.
Provide supplemental fluids such as IV, humidified oxygen,
and room humidification.
Monitor serial chest x-rays, ABGs, and pulse oximetry
readings.
31. 2. Impaired Gas Exchange related t oAlveolar-capillary
membrane changes Ventilation-perfusion imbalance, possibly
evidenced By dyspnea, abnormal skin color (e.g., pale,
dusky)tachycardia, restlessness, confusion ,Hypoxia
INTERVENTION

of pink or bloody sputum, pallor, cyanosis, change in level of
consciousness, severe dyspnea, and restlessness.
Monitor ABGs and pulse oximetry.
Administer oxygen therapy by appropriate .
32. 3. Risk for Infection related to inadequate primary defenses due to
decreased ciliary action, stasis of body fluids [respiratory
secretions]; Inadequate secondary defenses due to [presence of
existing infection], immunosuppression; chronic disease,
malnutrition, possibly evidenced By presence of signs and
symptoms establishes an actual diagnosis.
INTERVENTION

sputum and blood cultures.
34. 4. Activity Intolerance related To Imbalance between oxygen
supply and demand, General weakness, possibly evidenced by
report of weakness, fatigue, exertional dyspnea , Tachypnea,
Abnormal heart rate response to activity.
INTERVENTION

36. 6. Deficient Knowledge regarding condition, treatment, self-care, and discharge
needs, related to lack of exposure , information misinterpretation, lack of
recall possibly evidenced by reports the problem, inaccurate follow-through of
instructions.
INTERVENTION

40. RESEARCH INPUT
1. Oral health and ventilator-associated pneumonia among
critically ill patients: a prospective study.
Saensom D, Merchant AT, wara-Aswapati N, Ruaisungneon w, Pitiphat W
OBJECTIVE:- To evaluate the association between oral health and ventilator
associated pneumonia (VAP) among critically ill patients.
METHODS:- A prospective cohort study was conducted among 162 critically
ill patients who are newly intubated and treated with mechanical ventilator
in one tertiary hospital in Thailand. Oral health status was assessed using
Oral Health Assessment Tool (OHAT), Plaque Index (PI), and number of
teeth. VAP, defined as Clinical Pulmonary Infection Score>6, was assessed
on Day 4 after intubation. Hazard ratios and 95% confidence intervals (CIs)
were calculated using Cox proportional hazards regression adjusted for
confounders.
41. RESEARCH INPUT contd..
RESULTS:-
Critically ill patients had deteriorating oral health status after
intubation.
Early-onset VAP developed in 69 patients (42.6%), with VAP
incidence of 117 episodes per 1000 ventilator-days.
Patients with moderate-to-very poor oral hygiene assessed by
PI had increased VAP risk of 1.66-folds .The number of teeth
was not associated with VAP development.
CONCLUSIONS:- There is a strong association between poor
oral health and increased risk for early-onset VAP. Routine oral
care possibly prevents VAP development among critically ill
patients treated with mechanical ventilator.
