    Study Notes

    Sputum Characteristics

    • Yellow/greenish, cloudy, and thick sputum indicates a bacterial infection
    • Rusty or dark-colored sputum indicates blood and pneumococcal pneumonia
    • Purulent (pus-filled) and foul-smelling sputum may indicate bronchiectasis
    • Thick or sticky mucus is often seen in asthma or cystic fibrosis patients
    • Hemoptysis is characterized by bright red, frothy sputum, associated with pulmonary edema

    Breathing Patterns and Characteristics

    • Normal breathing rate (eupnea) is 10-18 inspirations per minute
    • Wheezing is a high-pitched whistling sound when airways are partially blocked
    • Stridor is a high-pitched crowing sound indicating upper airway obstruction
    • Rales are light, bubbly, or crackling sounds associated with serous secretions
    • Rhonchi are deeper, harsher sounds resulting from thick mucus
    • Absence of breath sounds may indicate non-aeration or collapse of a lung (atelectasis)

    Dyspnea and Cyanosis

    • Dyspnea is difficulty breathing, characterized by flaring nostrils, retraction of respiratory muscles, and use of accessory muscles
    • Orthopnea is dyspnea when lying down, which can be helped by laying on raised pillows or a wedge
    • Paroxysmal nocturnal dyspnea is sudden, acute dyspnea, common in people with left-sided heart failure
    • Cyanosis is a bluish discoloration of skin and mucous membranes due to large amounts of unoxygenated hemoglobin in the blood

    Pleural Pain and Friction Rub

    • Pleural pain results from inflammation or infection of the parietal pleura and increases with breathing or coughing
    • Friction rub is a soft sound due to rough membranes rubbing against each other, caused by inflammation in lobar pneumonia or lung infection

    Infectious Diseases

    Upper Respiratory Infections

    • Common cold: caused by over 200 viruses, spread through respiratory droplets and fomites
    • Sinusitis: bacterial infection secondary to a cold or allergy, causing nasal congestion, fever, sore throat, and facial pain
    • Laryngotracheobronchitis (croup): viral infection in young children, characterized by a barking cough
    • Epiglottitis: acute infection, rapid onset, fever, sore throat, and inspiratory stridor
    • Influenza (flu): viral infection, sudden onset, achy, fever, headache, and fatigue

    Lower Respiratory Infections

    • Bronchiolitis (Respiratory Syncytial Virus Infection): inflammatory obstruction of small airways, common in young children
    • Pneumonia: infection of the lungs, causing fever, chills, cough, and difficulty breathing
    • Tuberculosis (TB): bacterial infection, causing cough, fever, night sweats, and weight loss

    Diagnostic Tests

    • Spirometry: pulmonary function testing
    • Arterial blood gases: measuring oxygen, carbon dioxide, and bicarbonate levels, and serum pH
    • Oximetry: measuring oxygen saturation
    • Exercise tolerance testing: useful in patients with COPD for diagnosis and monitoring
    • Radiography: evaluation of tumors and infections like pneumonia and TB
    • Bronchoscopy: used in biopsy and checking for the site of a lesion or bleeding
    • Culture and sensitivity tests: identifying pathogens in exudate from upper respiratory and sputum
