[Hyperventilation and airway resistance. Bronchial spasms after hyperventilation].

R G Jaccard, R Scherrer, A A Bühlmann

    Schweizerische Medizinische Wochenschrift
    |December 8, 1979
    PubMed
    Summary

    The hyperventilation test reveals increased airway resistance in asthmatic patients, indicating heightened bronchoconstriction susceptibility. Bronchodilators can mitigate this hyperventilation-induced airway response.

    Area of Science:

    • Pulmonary Physiology
    • Respiratory Medicine

    Context:

    • Assessing airway reactivity is crucial for diagnosing and managing respiratory conditions.
    • Voluntary hyperventilation is a provocative test used to assess airway responsiveness.

    Purpose:

    • To evaluate the effect of voluntary hyperventilation on airway resistance and FEV1.0 in normal subjects, silicosis patients, and asthmatic patients.
    • To determine the utility of the hyperventilation test in identifying increased susceptibility to bronchoconstriction.

    Summary:

    • Voluntary hyperventilation significantly increased airway resistance in normal subjects (130-140%) and silicosis patients.
    • Asymptomatic asthmatic patients exhibited a pronounced rise in airway resistance (255%) and a reduction in FEV1.0 post-hyperventilation.
    • Bronchodilator administration effectively inhibited the hyperventilation-induced increase in airway resistance in both normal and asthmatic subjects.

    Impact:

    • The hyperventilation test serves as a valuable tool for detecting hyperresponsiveness and guiding clinical management of asthma and related conditions.
    • Findings highlight the potential of hyperventilation challenge to unmask underlying airway reactivity not apparent during baseline assessment.
