Study Notes
Introduction to Pneumonia
- Pneumonia is the inflammation of lung tissue (alveoli and bronchioles)
- It's mainly caused by infectious agents like bacteria, mycobacteria, fungi, parasites, and viruses.
Objectives
- Define pneumonia.
- Classify pneumonia based on causes, affected areas, and when the illness started.
- Identify the mode of transmission of pneumonia.
- List predisposing factors for pneumonia.
- Explain the pathophysiology of pneumonia.
- Describe the clinical manifestations of pneumonia.
- State the diagnostic evaluations for pneumonia.
- Explain the medical management of pneumonia.
- Detail nursing interventions for pneumonia.
- Outline preventive measures for pneumonia.
- Detail the prognosis of pneumonia.
Definition of Pneumonia
- Pneumonia is an inflammation of the lung tissue.
Classification of Pneumonia (According to Causes)
- Bacterial: The most common cause of community-acquired pneumonia (CAP). Streptococcus pneumoniae is a common bacteria type.
- Viral: Influenza viruses often cause viral pneumonia.
- Fungal: Candida and Aspergillus are two types of fungi that can cause pneumonia.
- Chemical: Caused by ingestion of kerosene or inhalation of irritating substances.
- Aspiration: Results from abnormal entry of material from the mouth or stomach into the trachea and lungs. Usually bacterial.
- Ventilator-associated (VAP): A type of aspiration pneumonia, pneumonia that develops in intubated and mechanically ventilated patients.
- Chemical: Inhalation of toxic chemicals can cause inflammation and tissue damage.
- Radiation: Results from damage to the lung mucosa during radiation therapy for breast or lung cancer.
- Hypostatic: Hypoventilation of lung tissue over a prolonged time. May occur in bedridden patients breathing with only part of their lungs.
Classification of Pneumonia (According to Areas Involved)
- Lobar: Inflammation confined to one or more lobes of the lung.
- Broncho: Patchy, diffuse, and scattered throughout both lungs. Pneumonia originates in bronchi and extends to surrounding lung tissue. This type is more common.
- Interstitial: Interstitial pneumonia.
Classification of Pneumonia (According to Location of Illness Onset)
- Hospital-acquired (HAP) or Nosocomial: Onset of pneumonia more than 48 hours after admission in a patient with no evidence of infection when admitted.
- Ventilator-associated (VAP): A type of HAP.
- Health care-associated (HCAP): Pneumonia that develops in outpatient settings or nursing homes.
- Community-acquired (CAP): Acute lung infection in patients who haven't been hospitalized, or within the first 48 hours of hospitalization.
Pneumonia in Immunocompromised Hosts
- Occurs with corticosteroid, immunosuppressive agent, chemotherapy, nutritional depletion, or broad-spectrum antimicrobial use.
- Or when patients have AIDS, genetic immune disorders, or long-term advanced life support technology.
Mode of Transmission
- Droplet infection: Bacteria and viruses in the nose, sinuses, and mouth can spread directly to the lungs.
- Aspiration: Food, liquids, vomit, or fluids from the mouth can be inhaled into the lungs.
- Organisms reach the lung by aspiration, inhalation, or hematogenous spread.
Pathophysiology
- Streptococci reach the alveoli and lead to inflammation and exudative pouring into the air spaces.
- White blood cells (WBCs) migrate to the alveoli, leading to consolidation.
- Involved areas become inadequately ventilated due to secretions and edema.
- Partial occlusion of alveoli and bronchi leads to a decrease in alveolar oxygen content, impacting venous blood oxygenation and leading to arterial hypoxemia.
Clinical Manifestations
- Shaking chills
- Rapidly rising fever
- Stabbing chest pain
- Tachypnea
- Use of accessory breathing muscles
- Cough with purulent, blood-tinged, or rusty sputum
- Shortness of breath
- Flushed cheeks
- Loss of appetite
- Low energy and fatigue
- Cyanosis (blue discoloration) of lips and nail beds
- Crackles and wheezes on lung auscultation
Diagnostic Evaluations
- History (recent respiratory infections)
- Physical Exam (Vitals)
- Chest X-ray
- Sputum examination (under microscope, culture, Gram stain)
- Pulse oximetry
- Arterial Blood Gas (ABGs)
- Complete blood count (CBC)
- Sputum cultures
- Bronchoscopy
- CT Scan
- Pleural fluid culture (thoracentesis)
Complications
- Pleurisy (inflammation of the pleura)
- Pleural effusion (fluid in the pleural space)
- Atelectasis (collapsed alveoli)
- Empyema (purulent exudate in pleural cavity)
- Lung abscess
- Sepsis (spread of bacteria)
- Acute respiratory distress syndrome (ARDS)
- Endocarditis (inflammation of the endocardium)
- Pericarditis (inflammation of the pericardium)
- Purulent arthritis
Medical Management
- Initiation of antibiotic treatment (depending on cultures)
- Antiviral or antifungal therapy
- Hydration to thin secretions
- Supplemental oxygen
- Individualized bed rest and activity
- Chest physical therapy and postural drainage
- Bronchodilators, Corticosteroids.
- Cough expectorants/suppressants
- Analgesics (for pain)
- Antipyretics (fever reducers)
Nursing Diagnoses
- Ineffective airway clearance
- Activity intolerance
- Imbalanced nutrition (less than body requirements)
- Deficient knowledge about treatment and preventive measures
- Risk for deficient fluid volume
Nursing Interventions
- Maintain a patent airway and adequate oxygenation.
- Obtain sputum specimens.
- Use suction if needed.
- Perform chest physiotherapy.
- Provide high-calorie, high-protein diet of soft foods.
- Prevent aspiration during feeding tubes.
- Administer appropriate medications.
- Control infection spread, dispose of secretions properly
- Provide a quiet, calm environment with frequent rest.
- Monitor ABG levels, especially in hypoxic patients.
- Assess the patient's respiratory status and auscultate breath sounds.
- Increase fluid intake.
- Monitor intake and output, skin turgor, vital signs, serum electrolytes.
- Evaluate medications effectiveness.
- Explain all procedures to the patient and family.
Preventive Measures
- Promote coughing and expectoration of secretions
- Change positions frequently
- Encourage deep-breathing and coughing exercises
- Administer chest physical therapy when indicated
- Suction patient if unable to cough.
- Prevent aspiration
- Prevent infections
- Cleanse respiratory equipment regularly
- Promote frequent oral hygiene
- Administer prescribed sedatives/opioids carefully to avoid respiratory depression
Prevention (Vaccines)
- Pneumococcal conjugate vaccine (PCV13): Given to children and adults of certain age groups, and those with compromised immune systems.
- Pneumococcal polysaccharide vaccine (PPSV23): Given to adults 65 years and older and children/younger adults with high-risk factors
- Seasonal Influenza vaccines
Prognosis
- With treatment, most patients show improvement within 2 weeks.
- Some patients (elderly or very ill) might take longer.
