Sputum: Examination

A comprehensive clinical examination is the basis for selecting further diagnostic steps:

  • General physical examination – including blood pressure, pulse, body temperature, body weight, body height; furthermore:
    • Inspection (viewing).
      • Skin, mucous membranes and sclerae (white part of the eye) [halitosis, foetor ex ore].
    • Auscultation (listening) of the heart [due todifferential diagnosis: heart failure (cardiac insufficiency)]
    • Examination of the lungs
      • Auscultation of the lungs [due todifferential diagnoses:
        • Bronchial asthma
        • Bronchial carcinoma (lung cancer)
        • Bronchiectasis (synonym: bronchiectasis; permanent outpouching of the bronchi as a result of the destruction of mainly elastic wall fibers).
        • Bronchocentric granulomatosis – granulomatous disease characterized by primary involvement of the bronchial or bronchiolar wall.
        • Chronic bronchitis
        • Chronic obstructive pulmonary disease (COPD)
        • Exacerbation of chronic bronchitis – acute exacerbation of chronic bronchitis.
        • Exogenous allergic alveolitis (hypersensitivity pneumonitis) – farmer’s lung, bird breeder’s lung, etc.
        • Influenza infections Upper and lower respiratory tract infections, unspecified.
        • Influenza (flu)
        • Papillomatosis – occurrence of multiple benign neoplasms, mostly in the respiratory tract.
        • Pneumonia (pneumonia)
        • Sinusitis (sinusitis)]
      • Bronchophony (checking the transmission of high-frequency sounds; the patient is asked to pronounce the word “66” several times in a pointed voice while the doctor listens to the lungs)[increased sound conduction due to pulmonary infiltration/compaction of lung tissue (e.g. e.g. in pneumonia) the consequence is, the number “66” is better understood on the diseased side than on the healthy side; in case of decreased sound conduction (attenuated or absent: e.g. in pleural effusion, pneumothorax, emphysema). The result is, the number “66” is barely audible to absent over the diseased part of the lung, because the high-frequency sounds are strongly attenuated]
      • Percussion (tapping) of the lungs [e.g., in emphysema; box tone in pneumothorax]
      • Vocal fremitus (checking the conduction of low frequencies; the patient is asked to pronounce the word “99” several times in a low voice while the physician places his hands on the patient’s chest or back)[increased sound conduction due to pulmonary infiltration/compaction of lung tissue (e. e.g. in pneumonia) the consequence is, the number “99” is better understood on the diseased side than on the healthy side; in case of reduced sound conduction (attenuated: e.g. atelectasis, pleural rind; strongly attenuated or absent: in case of pleural effusion, pneumothorax, pulmonary emphysema). The result is, the number “99” is barely audible to absent over the diseased part of the lung, because the low-frequency sounds are strongly attenuated]
  • If necessary, ENT medical examination [due topossible differential diagnosis: sinusitis].
