PneumoniaPneumonia DefinitionDefinition
Is an inflammatory Is an inflammatory process of the lung process of the lung parenchymaparenchyma that is that is commonly caused by commonly caused by infectious agents.infectious agents.
Classification of pneumonia
According to causesAccording to causes BacterialBacterial (the most common (the most common

of kerosene or inhalation of of kerosene or inhalation of irritating substance)irritating substance)
InhalationInhalation pneumonia (aspiration pneumonia (aspiration pneumonia)pneumonia)
Classification of pneumonia (cont…)
According to areas involvedAccording to areas involved
Lobar pneumonia; if one or more lobe is involved
Broncho-pneumonia; the pneumonic process has originated in one or more bronchi and extends to the surrounding lung tissue.
PneumoniaPneumonia Mode of transmission
Ways you can get pneumonia include:Ways you can get pneumonia include:
Bacteria and viruses living in your nose, Bacteria and viruses living in your nose, sinuses, or mouth may spread to your sinuses, or mouth may spread to your lungs.lungs.
You may breathe some of these germs You may breathe some of these germs directly into your lungs (droplets infection).directly into your lungs (droplets infection).
You breathe in (inhale) food, liquids, vomit, You breathe in (inhale) food, liquids, vomit, or fluids from the mouth into your lungs or fluids from the mouth into your lungs ((aspiration pneumonia).
PneumoniaPneumonia Predisposing factors
Immuno-suppresed patients Cigarette smoking Difficult swallowing (due to stroke,
dementia,parkinsons disease, or other neurological conditions)
Impaired consciousness ( loss of brain function due to dementia, stroke, or other neurological conditions)
PneumoniaPneumonia Predisposing factors
Chronic lung disease (COPD, bronchostasis)
Frequent suction Other serious illness such as heart disease, liver cirrhosis, and DM
Recent cold, laryngitis or flu
PneumoniaPneumonia Pathophysiology
The streptococci reach the alveoli and lead to inflammation and pouring of an exudates into the air spaces.
WBCs migrates to alveoli, the alveoli become more thick due to its filling consolidation, involved areas by inflammation are not adequately ventilated, due to secretion and edema. This will lead to partial occlusion of alveoli and bronchi causing a decrease in alveolar oxygen content.
PneumoniaPneumonia Pathophysiology (cont…)
Venous blood that goes to affected areas without being oxygenated and returns to the heart. This will lead to arterial hypoxemia and even death due to interference with ventilation.

PneumoniaNursing intervention (cont…)Nursing intervention (cont…)
Provide a quiet, calm environment, with frequent rest periods.
Monitor the patient’s ABG levels, especially if he’s hypoxic.
Assess the patient’s respiratory status. Auscultate breath sounds at least every 4 hours.
Monitor fluid intake and output.
Evaluate the effectiveness of administered medications.
Explain all procedures to the patient and family.
PneumoniaPreventive measures
Frequent turning of bed ridden patients and early ambulation as much as possible.
Coughing and breathing techniques.
Sterilization of respiratory therapy equipment
Suctioning of secretion in the unconscious who have poor cough and swallowing reflexes, to prevent aspiration of secretions and its accumulation.
PneumoniaPrognosis
With treatment, most patients will improve within 2 weeks. Elderly or very sick patients may need longer treatment.
