Key Features

++

Description

++

  • Inflammation of the lungs (specifically the alveoli)

  • Infection can be bacterial, viral, fungal, or parasitic

  • Pneumonitis is lung inflammation

  • Pneumonia is pneumonitis with pulmonary consolidation

++

Essentials of Diagnosis

++

  • Can develop from bronchitis, which is usually after a common cold (viral respiratory infection)

  • Case with mild symptoms is called walking pneumonia

++

General Considerations

++

  • Influenza is a systemic illness involving the respiratory tract

  • Antibiotics have limited to no role in the treatment of a virus

  • If caused by bacteria, antibiotics will be prescribed

  • Can develop secondary bacterial infection

  • Pneumonia can be life threatening

++

Demographics

++

  • Infants and young children

  • Elderly or frail

++

Clinical Findings

++

Signs and Symptoms2

++

  • Diarrhea

  • Increased heart beat

  • Low-grade fever

  • Runny nose

  • Malaise

  • Pleurisy

  • Sore throat

  • Cough with productive mucus

  • Edema

  • Chest tightness

  • Rales (crackling sounds in lungs)

  • Swelling of ankles, feet, legs

  • Wheezing

  • Raising shoulders allows increased lung air flow

  • Shortness of breath

  • Tensed muscles from dyspnea

++

Functional Implications

++

  • Disabling dyspnea when performing simple tasks

    • Arm elevation to reach into cabinet

    • Decreased exercise tolerance

    • Patients with mononucleosis should avoid contact sports for six weeks to avoid splenic rupture

    • Respiratory dysfunction limiting ones ability to function at work

++

Possible Contributing Causes

++

  • Flu virus

  • Respiratory syncytial virus

  • Rhinovirus

  • Herpes simplex virus

  • Severe acute respiratory syndrome (SARS)

  • Smoking

  • Air pollution

  • Allergies

  • Occupations with poor air quality

  • Long-term exposure to lung irritants

  • Environmental irritants

  • Periodontal disease

  • Immunodeficiency disorders

++

Differential Diagnosis

++

  • Influenza

  • Measles

  • Asthma

  • Chickenpox

  • Gastroesophageal reflux disease (GERD)

  • Ludwig's angina

  • Bronchiectasis

  • Adult cystic fibrosis (CF)

  • Kawasaki disease (KD)

  • Bronchitis

  • Goiter

  • Upper respiratory tract infection

  • Asthma (reversible)

  • Central airway obstruction

  • Lung tumor
