    Study Notes

    Pneumonia Overview

    • Pneumonia is an infection of the lung parenchyma, specifically the respiratory bronchioles and alveoli.
    • It is a significant cause of death in the United States, ranking eighth overall and first among infectious diseases.
    • Annually, approximately 1 million adults in the US seek hospital care for pneumonia, with around 50,000 deaths attributed to it.
    • Incidence and mortality rates are highest among older adults and individuals with debilitating conditions.
    • Pneumonia is the most common reason for adult hospital admissions apart from childbirth in the US.

    Hospital-Acquired Infections

    • Hospital-acquired infections (HAIs) such as ventilator-associated pneumonia (VAP) are more common in older adults and immunocompromised individuals.
    • VAP has a higher mortality rate compared to other HAIs.

    Respiratory System Defenses

    • The respiratory system is constantly exposed to potential infection due to its connection to the environment.
    • Numerous microorganisms in the oropharynx can be aspirated into the bronchial tree.
    • Anatomical and physiological defenses protect the lower respiratory tract from infection.
    • Impairment of these defenses increases the risk of infection.

    Factors Contributing to Pneumonia Risk

    • Suppressed cough reflex due to drugs, alcohol, or neuromuscular disease.
    • Narrowed and inflamed airways in asthma, trapping mucus and hindering oxygenation.
    • Respiratory epithelium vulnerability to bacterial infection following influenza or COVID-19 infection.

    Entry of Organisms

    • Microorganisms and foreign material occasionally enter the bronchial tree and lung parenchyma even in healthy individuals.
    • Aspiration of microbe-containing secretions from the oropharynx is the most common route of entry.
    • Inhalation of contaminated aerosolized water can cause viral and other types of pneumonia.
    • Bacteria can spread to the lungs via the bloodstream from infections elsewhere in the body.

    Development of Infection

    • For infection to occur, host defenses must be overwhelmed by the number of organisms or their virulence.

    Pneumonia Pathophysiology

    • Microorganisms colonizing alveoli trigger an inflammatory and immune response.
    • Antigen-antibody responses and endotoxins released by some organisms damage bronchial and alveolar mucous membranes.
    • This damage causes inflammation, leading to vascular congestion and edema.
    • Infectious debris and exudate can accumulate in the alveoli, hindering ventilation and gas exchange.
    • Pneumonia manifests in four distinct patterns: lobar pneumonia, bronchopneumonia, interstitial pneumonia, and miliary pneumonia.

    Lobar Pneumonia

    • Involves an entire lobe of the lung.
    • Initial minimal immune response allows bacteria to spread quickly.
    • Fluid exudate accumulates quickly, followed by red blood cells, neutrophils, damaged epithelial cells, and fibrin resulting in consolidation of the lung tissue.
    • Purulent exudate containing neutrophils and macrophages form.
    • Resolution occurs when enzymes break down the exudate, which is then reabsorbed, phagocytized, or expelled through coughing.

    Bronchopneumonia

    • Affects dependent portions of lung tissue with patchy consolidation.
    • Exudate primarily stays within the bronchi and bronchioles.
    • Less edema and alveolar congestion compared to lobar pneumonia.

    Interstitial Pneumonia

    • Involves the interstitium (the alveolar walls and connective tissue supporting the bronchial tree).
    • Inflammation can be patchy or diffuse, with lymphocytes, macrophages, and plasma cells infiltrating the alveolar septa.
    • Alveoli generally lack significant exudate, but protein-rich hyaline membranes may line them, disrupting gas exchange.

    Miliary Pneumonia

    • Caused by hematogenous spread of the pathogen.
    • Forms numerous discrete inflammatory lesions in the lungs.
    • Primarily affects individuals who are severely immunocompromised.
    • The immune response is usually poor, leading to significant damage to pleural tissue.

    Key Takeaways

    • Lobar pneumonia involves more extensive involvement and consolidation than bronchopneumonia.
    • Bronchopneumonia is more localized and typically affects specific lung segments.
    • Interstitial pneumonia impacts the supporting structures and is associated with hyaline membranes that impair gas exchange.
    • Miliary pneumonia indicates hematogenous spread, particularly affecting those with weakened immune systems.

    Pneumonia Causes

    • Pneumonia can be caused by infectious or noninfectious factors.
    • Infectious causes include bacteria, viruses, fungi, protozoa, and other microbes.
    • Noninfectious causes include aspiration of gastric contents and inhalation of toxic or irritating gases.

    Bacterial Pneumonia

    • Bacterial pathogens usually originate from the upper airways.
    • They enter the alveoli and trigger an immune response.
    • This response results in cellular debris and fluid accumulation within the alveoli, leading to consolidation.
    • Consolidation typically affects only one lobe of the lung, but severe infections can affect multiple lobes.

    Viral Pneumonia

    • Viruses directly invade pneumocytes, replicate, and spread as the cells die.
    • This viral spread results in a widespread immune response throughout the lungs.
    • The edema produced from this process appears as a scattered, patchy pattern on radiographs, known as bronchopneumonia.

    Aspiration Pneumonia

    • Aspiration of food, vomit, gastric reflux, or hydrocarbons causes chemical injury and inflammation.
    • Materials with a lower pH increase airway inflammation, reducing natural defenses and promoting microbial invasion.
    • Aspiration also carries oral flora, increasing the potential for infectious organisms.

    Pneumonia Classifications

    • Pneumonias are classified as community-acquired, healthcare-associated, or opportunistic.
    • Each classification has different implicated organisms.
    • Streptococcus pneumoniae (pneumococcus), a gram-positive bacterium, is the most common cause of community-acquired pneumonia, responsible for approximately 50% of hospital admissions due to this condition.
    • Staphylococcus aureus and gram-negative bacteria are frequently implicated in healthcare-associated pneumonia.
    • Pneumocystis jiroveci typically causes infections in immunocompromised individuals.

    Community-Acquired Pneumonia (CAP)

    • Streptococcus pneumoniae (pneumococcus) is the most common cause of CAP
    • Mycoplasma pneumoniae, Haemophilus influenzae, Klebsiella pneumoniae, Influenza virus, Chlamydia pneumoniae, and Legionella pneumophila are also frequent causes of CAP

    Healthcare-Associated Pneumonia (HAP)

    • Staphylococcus aureus and Pseudomonas aeruginosa are common causes of HAP due to their antibiotic resistance
    • Haemophilus influenzae, Klebsiella pneumoniae, and Escherichia coli can also cause HAP

    Opportunistic Pneumonia

    • Pneumocystis jiroveci and Cytomegalovirus are prevalent in individuals with compromised immune systems
    • Mycobacterium tuberculosis, Atypical mycobacteria, and Fungi can also cause opportunistic pneumonia

    Pneumonia Etiology

    • Pneumonia classifications are based on the infecting organism.
    • Some types of pneumonia include bacterial, Legionnaires, primary atypical, viral, Pneumocystis jiroveci, and aspiration pneumonia.
    • The pathogenesis of pneumococcal (Streptococcus pneumoniae) pneumonia is well understood.
    • These bacteria live in the upper respiratory tract of up to 70% of adults.
    • They spread through direct contact with droplets released by other people.
    • In many cases, infection occurs due to aspirating resident bacteria.
    • Pneumococcal pneumonia typically presents as lobar pneumonia with lower lobes affected due to gravity.

    Pneumococcal Pneumonia

    • Typically resolves without complications
    • Most common complication is pleuritis (inflammation of the pleura)
    • Normal lung structure is restored when the infection is gone

    Other Pneumonia Types

    • Staphylococcus aureus and gram-negative bacteria can cause extensive lung damage, leading to necrosis, lung abscess, and empyema
    • Klebsiella pneumonia can cause progressive lung destruction and functional impairment

    Lung Abscess

    • Local area of necrosis and pus formation within the lung
    • Relatively uncommon
    • Develops slowly and manifests with weight loss, malaise, night sweats, fever, and a productive cough
    • Sputum is foul smelling and foul tasting
    • Rupture of the abscess into a larger airway can cause a sudden increase in purulent sputum production

    Empyema

    • Accumulation of purulent exudate in the pleural cavity
    • Identified by chest x-ray or CT
    • Can be treated with thoracentesis (needle aspiration of fluid) or chest tube placement for drainage

    Bacterial Pneumonia Presentation

    • Usually presents acutely with rapid onset of shaking chills, fever, and cough producing rust-colored or purulent sputum.
    • Chest aching or pleuritic pain is common.
    • Limited breath sounds, fine crackles or rales are heard in the affected lung area.
    • A pleural friction rub may be audible.
    • Dyspnea and cyanosis may occur if the involved area is large and gas exchange is impaired.

    Bronchopneumonia Presentation

    • Presents with a more insidious onset, including low-grade fever, cough, and scattered crackles.
    • Dyspnea is less common with bronchopneumonia.

    Atypical Pneumonia Presentation

    • Older adults and debilitated individuals may present with atypical manifestations, including minimal cough, scant sputum, and little evidence of respiratory distress.
    • Fever, tachypnea, and altered mentation or agitation can be the primary symptoms.

    Legionnaires Disease

    • A form of bronchopneumonia caused by Legionella pneumophila.
    • A gram-negative bacterium found in water, especially warm, standing water.
    • Occurs sporadically and in outbreaks.
    • Contaminated water-cooled air-conditioning systems and other water sources contribute to its spread.
    • Smokers, older adults, and individuals with chronic diseases or impaired immune defenses are at higher risk.
    • Symptoms develop gradually, 2 to 10 days after exposure.
    • Common manifestations include dry cough, dyspnea, general malaise, chills, fever, headache, confusion, diminished appetite, diarrhea, myalgias, and arthralgias.
    • Lung tissue consolidation is patchy or lobar.
    • Hospitalized patients with Legionnaires disease have a mortality rate close to 25%.

    Primary Atypical Pneumonia

    • Caused by Mycoplasma pneumoniae
    • Often presents as pharyngitis or bronchitis
    • Characterized by patchy inflammatory changes in the alveolar septa and interstitial tissue of the lung
    • Alveolar exudate and consolidation of lung tissue are not features of atypical pneumonia
    • Primarily affects young adults, especially college students and military recruits
    • Highly contagious
    • Symptoms resemble those of viral pneumonia, with fever, headache, myalgias, and arthralgias
    • Cough is dry, hacking, and nonproductive
    • Often referred to as "walking pneumonia" due to its mild nature and systemic manifestations

    Viral Pneumonia

    • Accounts for approximately 10% of pneumonias in adults
    • Most common causative organisms are influenza virus and adenovirus
    • Incidence of CMV pneumonia is increasing in immunocompromised individuals
    • Other viruses, such as herpes viruses and measles virus, can also cause pneumonia
    • Lung involvement is limited to the alveolar septa and interstitial spaces
    • Typically a mild disease affecting older adults and people with chronic conditions
    • Often occurs in community epidemics
    • Symptoms include headache, fever, fatigue, malaise, muscle aches, and a dry cough

    Pneumocystis jiroveci Pneumonia

    • Caused by Pneumocystis jiroveci, a common parasite worldwide
    • Primarily affects individuals with AIDS or other significant immunodeficiency
    • Immunity is nearly universal, except in immunocompromised individuals
    • Risk factors include immunosuppressive or cytotoxic drug treatment, organ transplantation, and genetic or acquired immunodeficiency
    • Produces patchy involvement throughout the lungs, causing thickening, edema, and filling of alveoli with foamy, protein-rich fluid
    • Severely impairs gas exchange
    • Abrupt onset with fever, tachypnea, shortness of breath, and a dry, nonproductive cough
    • Can lead to significant respiratory distress, including intercostal retractions and cyanosis

    Aspiration Pneumonia

    • Aspiration pneumonia occurs when gastric contents are aspirated into the lungs, causing chemical and bacterial pneumonia.
    • Major risk factors include:
      • Emergency surgery without 8 hours of NPO (e.g., emergency cesarean birth)
      • Depressed cough and gag reflexes
      • Impaired swallowing
      • Older patients
      • Patients with advanced dementia
      • Enteral nutrition via nasogastric or gastric tubes

    Risk Factors

    • Infants and young children have immature immune systems, increasing pneumonia risk.

      • Preventing nausea and gastric distention
      • Serving thickened liquids
      • Performing swallowing tests, especially for stroke patients

    Pneumonia Prevention

    • Prevention is crucial for managing pneumonia.
    • Early identification of the infecting organism, appropriate treatment, and support of respiratory function are essential for recovery.
    • Pneumonia remains a serious disease with a high mortality rate, particularly in older adults and individuals with chronic diseases.
    • Vaccines provide protection against common bacterial and viral pneumonias.
    • Pneumococcal polysaccharide vaccine (PPSV23) is recommended for high-risk individuals to reduce their risk of adverse outcomes from bacterial pneumonia.
    • PPSV23 is recommended for adults over 65 and individuals with chronic diseases (e.g., heart disease, lung disease, alcoholism, diabetes, cirrhosis).
    • Other high-risk groups include those with chronic renal failure, immunocompromised individuals, smokers, asthmatics, and individuals receiving certain medications.
    • Revaccination with PPSV23 is recommended for individuals with immunosuppressive conditions and adults over 65 who were previously vaccinated more than 5 years ago.
    • Pneumococcal conjugate vaccine (PCV13) is recommended for adults over 65 who are immunocompromised and have a cerebrospinal fluid leak or a cochlear implant.

    Infection Of the Lower Respiratory Tract

    • Infection of the lower respiratory tract leads to both local and systemic effects
    • Local effects include cough, excess mucus production, shortness of breath (dyspnea), and hypoxia
    • Hypoxia can proceed to apnea due to respiratory collapse
    • Other local effects include hemoptysis (bloody sputum) and chest pain
    • Systemic effects include fever, diminished appetite and malaise
    • Cyanosis (gray to blue or purple skin color caused by deoxygenated hemoglobin) is a systemic effect secondary to hypoxia
    • Other systemic effects can be a manifestation of impaired gas exchange

    Pneumococcal (Lobar) Pneumonia

    • Abrupt onset
    • Productive cough with purulent (pus-filled) or rust-colored sputum
    • Pleuritic chest pain
    • Decreased breath sounds and crackles over the affected lung area

    • Fever

    Bacteremia

    • Occurs when bacteria from the lungs enter the bloodstream.
    • Can spread infection to other organs and tissues, leading to serious complications.
    • Increases the risk of death.

    Complications of Bacteremia

    • Meningitis: inflammation of the membranes that protect the brain and spinal cord.
    • Endocarditis: infection of the inner lining of the heart, potentially damaging heart valves.
    • Peritonitis: inflammation of the peritoneum, the lining of the abdominal cavity, causing severe abdominal pain.

    Septicemia and Septic Shock

    • Septicemia: a systemic, overwhelming bloodstream infection originating from the lungs.
    • Septic Shock: a life-threatening condition resulting from uncontrolled septicemia, characterized by:
      • Severe hypotension (dangerously low blood pressure)
      • Multi-organ dysfunction due to insufficient blood flow and oxygenation.
    • Requires immediate medical attention.
    • Can have high mortality rates.

    Key Points

    • Bacteremia is a serious complication of pneumonia.
    • Early identification and treatment of pneumonia and its complications are crucial for preventing progression to severe states like septicemia and septic shock.

    Fever

    • Pathogens cause the hypothalamus to increase body temperature set point, attempting to kill them.
    • Increase fluid intake.
    • Administer antipyretics: ibuprofen or acetaminophen.
    • Aspirin is contraindicated in children due to Reye syndrome risk.
    • Minimize clothing and coverings.
    • Monitor temperature frequently.
    • Tepid baths can be used if other therapies fail or fever is too high.

    Apnea

    • Respiratory muscle fatigue is a complication in pneumonia patients.
    • Use a cardiorespiratory monitor to detect episodes.
    • Reduce work of breathing (WOB) by assisting with airway clearance, positioning, and oxygen administration.
    • Recurrent or severe apnea requires intubation and mechanical ventilation.

    Cough

    • Fluid and debris accumulation in airways cause coughing.
    • Increase fluid intake to thin secretions.
    • Frequent position changes prevent atelectasis and drain airways.
    • Chest physiotherapy and airway suctioning promote airway clearance.
    • Mucolytics help expectorate sputum and bronchodilators open airways for sputum movement.

    Hypoxia

    • Fluid in airways impairs gas exchange.
    • Administer oxygen.
    • Encourage coughing and deep breathing to clear airways and promote gas exchange.
    • Monitor vital signs and oxygen saturation.
    • Position for optimal airway clearance.

    Fever

    • Pathogens trigger the hypothalamus to raise body temperature to fight infection
    • Increase fluid intake to prevent dehydration
    • Administer antipyretics like ibuprofen or acetaminophen
    • Aspirin can be used for adults, but not children due to the risk of Reye Syndrome
    • Minimize clothing and coverings to regulate body temperature
    • Monitor temperature frequently to detect spikes or trends
    • Tepid baths can be used if fever is unresponsive to other measures or becomes dangerously high

    Apnea

    • Respiratory muscle fatigue can cause periods of slowed or stopped breathing
    • Use a cardiorespiratory monitor to track heart and breathing rates
    • Reduce workload of breathing, such as aiding airway clearance, adjusting patient positioning, and administering oxygen
    • Severe or recurrent apnea may necessitate intubation and mechanical ventilation

    Cough

    • Accumulation of fluid and debris in the airways causes coughing as a response to clear them
    • Increase fluid intake for easier expulsion of secretions
    • Frequent position changes to prevent lung collapse and allow drainage of lungs
    • Chest physiotherapy can be used to assist in airway clearance
    • Airway suctioning is necessary for weak or ineffective coughing
    • Administer mucolytics to promote sputum expectoration and bronchodilators to open airways

    Hypoxia

    • Fluid buildup in the airways disrupts gas exchange, leading to insufficient oxygen levels
    • Administer oxygen to maintain adequate blood oxygen levels
    • Encourage deep breathing and coughing to clear airways and improve gas exchange
    • Monitor vital signs and oxygen saturation regularly
    • Position patient in ways that promote airway clearance, like semi-Fowler’s or high-Fowler’s position

    Collaboration

    • Collaboration in caring for a patient with pneumonia includes nurses, doctors, phlebotomists, respiratory therapists, radiologists, and speech-language pathologists.
    • In some cases, consultation with an infectious disease specialist or a pulmonologist may be necessary.
    • Patients and families may want to talk with the hospital chaplain or their own spiritual leader.

    Diagnostic Tests

    • Chest X-ray: Used to determine the extent and pattern of lung involvement.
      • Densities on the film indicate fluid, infiltrates, consolidated lung tissue, and atelectasis (areas of alveolar collapse).
    • CT Scan: Provides a more detailed image of pulmonary tissue and may be used when the chest x-ray is not diagnostic.
    • Sputum Gram Stain: Rapidly identifies the infecting organisms as gram-positive or gram-negative bacteria.
      • Antibiotic therapy can be directed at the predominant type of organism until culture and sensitivity results are obtained.
    • Sputum Culture and Sensitivity: Ordered to identify the infecting organism and determine the most effective antibiotic therapy.
      • It is important to obtain secretions from the lower respiratory tract, not from the mouth and nasal passages.
    • CBC with WBC Differential: Shows an elevated WBC (greater than or equal to ) with increased circulating immature leukocytes (a left shift) in response to the infectious process.
      • WBC changes are minimal in viral and other pneumonias.
    • Serology Testing: (Blood tests to detect antibodies to respiratory pathogens) may be used to identify the infecting organism when blood and sputum cultures are negative.
    • Pulse Oximetry: Noninvasive method of measuring arterial oxygen saturation, ordered to continuously monitor gas exchange.
      • Normal oxygen saturation is 95% or higher.
      • An oxygen saturation of less than 95% may indicate impaired alveolar gas exchange.
    • Arterial Blood Gas: May be ordered to evaluate gas exchange.
      • Respiratory secretions or pleuritic pain can interfere with alveolar ventilation.
      • Alveolar inflammation can interfere with gas exchange across the alveolar–capillary membrane, especially if exudate or consolidation is present.
      • An arterial partial pressure of oxygen (PaO2) of less than 75 to 80 mmHg indicates impaired gas exchange or alveolar ventilation.
    • Fiberoptic Bronchoscopy: May be done to obtain a sputum specimen or remove secretions from the bronchial tree.

    Pneumonia Medications

    • Antibiotics are used to treat pneumonia.
    • Bronchodilators are used to reduce bronchospasm and improve ventilation.
    • Initial antibiotic therapy is based on sputum Gram stain, organism sensitivity to antibiotics, and chest x-ray findings.
    • Cardiovascular disease and residence in a long-term care facility are factors considered in initial antibiotic choice.
    • Broad-spectrum antibiotics are typically ordered until culture and sensitivity results are available.
    • Examples of broad-spectrum antibiotics include macrolides (clarithromycin, azithromycin, erythromycin), penicillins, second- or third-generation cephalosporins, and fluoroquinolones (ciprofloxacin).

    Antibiotic Therapy for Common Pneumonia Pathogens

    • Streptococcus pneumoniae:
      • First-line treatment: Penicillin G or amoxicillin (if not resistant)
      • Alternatives: Erythromycin, cephalosporins, doxycycline, fluoroquinolones, clindamycin, vancomycin, TMP-SMZ, linezolid
    • Haemophilus influenzae:
      • First-line treatment: Second- or third-generation cephalosporins, erythromycin, doxycycline, azithromycin, TMP-SMZ
      • Alternatives: Fluoroquinolones, clarithromycin
    • Staphylococcus aureus:
      • First-line treatment: Penicillinase-resistant penicillin (e.g., nafcillin), vancomycin for methicillin-resistant strains (MRSA)
      • Alternatives: Cephalosporins, clindamycin, ciprofloxacin, fluoroquinolones, TMP-SMZ
    • Mycoplasma pneumoniae:
      • First-line treatment: Erythromycin, doxycycline
      • Alternatives: Clarithromycin, azithromycin, fluoroquinolones
    • Klebsiella pneumoniae:

    • Pneumocystis jiroveci:
      • First-line treatment: TMP-SMZ, pentamidine (inhaled and intravenous)
    • Chlamydia pneumoniae:
      • First-line treatment: Azithromycin
      • Alternatives: Tetracyclines, fluoroquinolones

    Key Considerations for Antibiotic Choice

    • Patient factors: Allergies, previous exposure to antibiotics, and overall health status can influence antibiotic choice.
    • Sensitivity patterns: Culture and sensitivity testing helps identify the specific pathogen and its susceptibility to different antibiotics.
    • Resistance: Use of broad-spectrum antibiotics to cover a range of potential pathogens while waiting for culture and sensitivity results.
    • Alternatives: A variety of alternative antibiotics can be used for patients with allergies, resistance issues, or other medical considerations.

    Bronchodilators

    • Bronchodilators can be used to improve ventilation and reduce hypoxia, especially in cases where the inflammatory response to an infection causes bronchospasm and constriction.
    • The main categories of bronchodilators include sympathomimetic drugs (beta-adrenergic agonists), anticholinergic drugs, and methylxanthines.
    • Sympathomimetic drugs, such as albuterol (short-acting) and salmeterol (long-acting), are commonly used.
    • Anticholinergic drugs like tiotropium are also utilized.
    • Methylxanthines, like theophylline and aminophylline, are less frequently used due to potential side effects.

    Mucus Management

    • Medications like acetylcysteine and guaifenesin, found in expectorant cough syrups, can help liquefy mucus, making it easier to cough up.
    • Increasing fluid intake is considered the most effective way to thin mucus.

    Oxygen Therapy

    • Oxygen therapy may be necessary for patients with pneumonia experiencing hypoxia (low blood oxygen levels).
    • Inflammation thickens the alveolar-capillary membrane, hindering gas diffusion across the membrane.
    • Increasing the inspired oxygen concentration above room air (21%) increases the partial pressure of oxygen in the alveoli and promotes diffusion into the capillaries.

    Oxygen Delivery Systems

    • Oxygen can be administered through low-flow systems like nasal cannulas, simple face masks, partial rebreathing masks, and nonrebreather masks.
    • Nasal cannulas provide 24-45% oxygen concentration with flow rates of 2-6 L/minute.
    • Simple face masks deliver 40-60% oxygen with 5-8 L/minute flow rates.
    • Nonrebreather masks can provide up to 100% oxygen, the highest concentration possible without mechanical ventilation.
    • High-flow systems, such as Venturi masks, are used when precise oxygen regulation is needed.
    • Venturi masks control the oxygen/room air ratio, enabling precise delivery of oxygen percentages from 24 to 50%.

    Severe Hypoxia

    • In severe cases of hypoxia, noninvasive ventilation or intubation and mechanical ventilation may be required.

    Supportive Care in Pneumonia

    • Nonpharmacologic therapy plays a crucial role in treating pneumonia.
    • Maintaining an open airway is key, along with adequate fluid intake and rest.
    • Increased fluid intake helps liquefy thick mucus, making it easier to cough up.
    • Aim for a daily fluid intake of 2500-3000 mL.
    • If oral intake is limited, IV fluids and nutrition may be necessary.
    • Incentive spirometry encourages deep breathing and helps clear secretions.
    • Endotracheal suctioning can be implemented if coughing proves ineffective.
    • Bronchoscopy may be used for pulmonary hygiene and to remove secretions.
    • Chest physiotherapy, including percussion, vibration, and postural drainage, can help reduce lung consolidation and prevent atelectasis.

    Percussion and Vibration with Postural Drainage

    • Percussion and vibration work in tandem with postural drainage to clear mucus from lung segments.
    • Postural drainage uses gravity to move secretions from a specific lung section.
    • To facilitate drainage, position the patient with targeted lung sections above the trachea or main bronchus.
    • Several positions are needed to drain all lung segments.
    • Bronchodilators or nebulizer treatments often precede postural drainage.
    • Avoid administering postural drainage before meals to prevent nausea and vomiting.

    Pneumonia in Children

    • Children are more susceptible to pneumonia due to their immature airways and increased oxygen consumption.
    • The size of airways, number of alveoli, breathing muscle use, and oxygen consumption all play a role in pneumonia severity in children.
    • Children experience a rapid increase in oxygen consumption when in respiratory distress, leading to more rapid respiratory muscle fatigue and increased risk of hypoxia and respiratory arrest compared to adults.
    • Early symptoms of pneumonia in children include restlessness, sweating, rapid heart rate, and rapid breathing.
    • As pneumonia worsens, children may show nasal flaring, retractions of the chest, and grunting sounds.
    • Severe hypoxia in children is indicated by a significant decrease in respiratory rate and heart rate, a sign of impending respiratory arrest.
    • Young children might experience a drop in temperature instead of fever due to an immature immune system.
    • Reduced breath sounds may be present if lung consolidation occurs.
    • Children with pneumonia may experience poor feeding, nausea, vomiting, and abdominal pain.
    • Older children may present with dullness on chest percussion, increased vibrations felt on palpation, and enhanced voice sounds.
    • Obtaining a sputum culture from a child is challenging except in cases of intubation and mechanical ventilation.
    • Pneumonia treatment is based on symptoms, symptom onset speed, season, influenza testing availability, physical examination, and any underlying conditions or immune deficiencies.
    • Blood cultures may be performed to rule out systemic infection.
    • Bacterial pneumonia usually presents with rapid symptom progression, high fever, and low white blood cell count, while viral pneumonia presents with more gradual symptoms and lower fevers.
    • Early detection is crucial for managing pneumonia in children, enabling home treatment whenever possible.
    • Assessment guidelines for pediatric patients differ from those for adults due to children's unique anatomy and physiology.

    Position of Comfort

    • Observe if child prefers lying down, sitting up, or assuming the tripod position

    Vital Signs

    • Assess respiratory rate, depth, and ease
    • Assess pulse rate and strength

    Lung Auscultation

    • Listen for bilateral breath sounds
    • Note any diminished or absent breath sounds
    • Identify adventitious sounds like wheezes, crackles, or rhonchi

    Respiratory Effort

    • Check for audible breath sounds (inspiratory and expiratory) or stridor
    • Note if grunting occurs during expiration
    • Assess if breathing is labored
    • Observe for retractions, use of accessory muscles, and nasal flaring
    • Note tachypnea (abnormally fast respiratory rate)
    • Determine if the child can speak a full sentence without pausing for breath
    • In infants, check cry strength and observe simultaneous chest and abdomen rise during inspiration
    • Assess for paradoxical breathing

    Color

    • Assess mucous membrane color (pink, pale, mottled, or cyanotic)
    • Determine if crying improves or worsens the child's color

    Cough

    • Note if cough is dry, wet, brassy, or croupy
    • Assess the coughing effort

    Behavior Change

    • Note any sudden changes in behavior, such as irritability, restlessness, or a change in responsiveness

    Family History

    • Inquire about family history of asthma or cystic fibrosis

    Fluid Intake for Pediatric Patients

    • Increasing fluid intake helps to thin out mucus and make it easier to remove.
    • Rapid fluid replacement is crucial in pediatric sepsis.
    • Aspirin is never prescribed to children due to the risk of Reye syndrome.

    Calculating Daily Fluid Requirements

    • The daily maintenance fluid requirement for children is calculated by weight using three steps:
      • For the first 10 kg: 100 mL/kg/day
      • For the second 10 kg: 50 mL/kg/day
      • For every kg over 20 kg: 20 mL/kg/day
    • The maximum daily fluid intake is 2400 mL.

    Example Calculation

    • A child weighing 53 lb (24 kg) requires 1580 mL of fluid per day.
      • First 10 kg: 100 mL/kg/day x 10 kg = 1000 mL/day
      • Second 10 kg: 50 mL/kg/day x 10 kg = 500 mL/day
      • Additional weight (4 kg): 20 mL/kg/day x 4 kg = 80 mL/day
      • Total: 1000 mL + 500 mL + 80 mL = 1580 mL/day

    Respiratory Function Changes in Older Adults

    • Cilia decrease with age, leading to reduced airway clearance
    • Gag and cough reflexes weaken, making it harder to clear the airway
    • Dehydration is more common due to decreased thirst perception, resulting in thicker mucus that is difficult to expectorate
    • Immune function decreases with aging, increasing susceptibility to infections

    Risk Factors for Pneumonia in Older Adults

    • Immobility increases the risk of aspiration and infection
    • Smoking history leads to compromised lung function and increased susceptibility to infection
    • Surgical procedures can weaken the immune system and increase infection risk
    • Multiple medications may suppress immune function or have respiratory side effects
    • Malnutrition weakens the immune system and overall health
    • Comorbid conditions such as asthma, COPD, and heart disease increase the risk of pneumonia

    Pneumonia in Older Adults

    • Pneumonia can progress rapidly in older adults
    • The only sign of infection may sometimes be worsening of existing pulmonary conditions
    • Pneumonia and complications are significant contributors to ICU admissions in older adults

    Pneumonia Nursing Assessment

    • Observation and Interview: Assess the patient's breathing (shortness of breath, difficulty breathing, cough, sputum color and consistency) and skin color. Ask about the patient's current symptoms, duration, chest pain, recent illnesses (upper respiratory or acute) and chronic diseases (diabetes, lung disease, heart disease, etc.). Inquire about medications, allergies and immunization status.
    • Physical Examination: Observe patient's level of consciousness and vital signs, including temperature. Examine skin color and temperature. Pay close attention to respiratory excursion, use of accessory muscles, and lung sounds. Monitor oxygen saturation, being alert to levels suggesting hypoxia.
    • Ongoing Respiratory Assessments: Essential for all pneumonia patients. Frequency depends on the patient's clinical acuity and symptom severity. Assess breath sounds, vital signs, oxygen saturation, and general assessment at least every 4 hours for stable patients.

    Nursing Diagnoses for Pneumonia

    • Decreased airway clearance: This relates to difficulty in effectively moving mucus and secretions from the airway.
    • Ineffective breathing pattern: Reflects an inability to maintain adequate ventilation as the lungs are affected by pneumonia.
    • Fever: A common symptom of pneumonia, indicating the body's immune response to the infection.
    • Inability to tolerance activity: The infection can cause weakness and fatigue, limiting daily activities.
    • Anxiety related to hypoxia: Caused by the reduced oxygen levels, resulting in fear and worry.
    • Weight loss related to altered breathing pattern: Difficult breathing can make eating and digesting food challenging, leading to weight loss.
    • Sleep disturbance related to orthopnea: Difficulty breathing when lying down, forcing the patient to sleep sitting up.

    Nursing Care Goals

    • Restore optimal respiratory function
    • Maintain normal body temperature
    • Obtain adequate sleep and rest

    • Administer prescribed medications and monitor their effects
    • Administer bronchodilators or other respiratory medications as ordered
    • Monitor for adverse effects of respiratory medications

    Effective Ventilation for Lung Infections

    • Assessment: Assess respiratory rate, depth, and lung sounds frequently (adults at least every 4 hours, children every 1-2 hours). Tachypnea and diminished or adventitious breath sounds may indicate respiratory compromise.
    • Rest: Provide for rest periods to reduce metabolic demands, fatigue, and work of breathing. This promotes effective breathing patterns.
    • Pain Management: Assess for pleuritic discomfort and provide analgesics as ordered to minimize splinting and promote ventilation.
    • Chest Splinting: Teach chest splinting using a pillow or teddy bear to decrease pain during coughing, promoting pulmonary hygiene.
    • Anxiety Management: Reassure the patient in a calm, soft voice to reduce anxiety, which can exacerbate respiratory distress. Provide oxygen as ordered to reduce hypoxia and associated anxiety.
    • Relaxation Techniques: Teach relaxation techniques such as visualization and meditation to help decrease respiratory rate and perceived distress.

    Activity and Rest Balance

    • Activity Tolerance: Assess the patient's activity tolerance, noting changes in pulse, respirations, dyspnea, diaphoresis, or cyanosis to determine activity limits.
    • Self-Care Assistance: Assist patients with self-care activities, such as bathing, to reduce energy demands.
    • Rest Periods: Plan for rest periods between scheduled activities to minimize fatigue and improve activity tolerance. Group minor activities together, but allow for rest after major activities like chest physiotherapy or showering.
    • Assistive Devices: Provide assistive devices to facilitate movement and reduce energy demands.
    • Family Support: Teach the family ways to minimize stress and anxiety levels, as these increase metabolic demands and decrease activity tolerance.

    • Emotional Support: Provide emotional support and reassurance that strength and energy will return to normal once the infectious process resolves and oxygen supply and demand balance is restored.

    Activity Intolerance

    • Inability to tolerate activity could be an early indicator of compromised cardiorespiratory function, especially in senior individuals and those with pre-existing heart conditions.
    • Report any new or worsening activity intolerance to the healthcare provider.

    Pneumonia Treatment

    • Patients with pneumonia are usually treated at home unless their respiratory condition deteriorates significantly or they have underlying risk factors.

    Caregiver Evaluation

    • Caregivers should be educated to assess care outcomes and identify signs and symptoms requiring immediate consultation with the primary healthcare provider.

    Expected Outcomes

    • Normal body temperature for 24 hours.
    • Adequate sleep and rest without interruptions from coughing or difficulty breathing when lying down.
    • Sufficient fluid and calorie intake.
    • Effective cough to clear the airway.
    • Oxygen saturation exceeding 90%.

    Hospital Admission

    • Patients unable to properly manage their airway are likely admitted to the hospital for further interventions, such as suctioning and additional treatments.

    Aspiration Pneumonia

    • Aspiration pneumonia is a frequent issue in adults with swallowing difficulties and compromised airway protection.

    Treatment Goals

    • The goal of interventions is to restore appropriate oxygen saturation levels and prevent further infections.

    Pneumonia: Lung Inflammation

    • An inflammatory condition of the lung parenchyma, primarily caused by infection, affecting the respiratory bronchioles and alveoli.

    • Causes can be bacteria, viruses, fungi, or inhaled irritants.

    • The disease leads to fluid and exudate accumulation in the alveoli, impairing gas exchange and causing respiratory symptoms.

    Pneumonia Classification

    • Community-Acquired Pneumonia (CAP): Acquired in the community setting.
    • Hospital-Acquired Pneumonia (HAP): Acquired in a hospital setting, typically more than 48 hours after admission.
    • Ventilator-Associated Pneumonia (VAP): Acquired in a hospital or healthcare setting, specifically while on a mechanical ventilator.
    • Aspiration Pneumonia: Occurs when aspirated material, such as food or vomit, enters the lungs.

    Causative Organisms

    • Bacterial Pneumonia: Common causes include Streptococcus pneumoniae, Haemophilus influenzae.
    • Viral Pneumonia: Influenza virus, respiratory syncytial virus (RSV), and others.
    • Fungal Pneumonia: Less common, seen in immunocompromised individuals, such as people with HIV or those receiving chemotherapy.

    Risk Factors
