Hyperventilation syndrome: a review.

W P Morgan

    American Industrial Hygiene Association Journal
    |September 1, 1983

    Summary
    This summary is machine-generated.

    Hyperventilation syndrome, a psychophysiological condition, presents with symptoms like breathlessness and trembling. This syndrome can be triggered by overbreathing or CO2 challenges, with symptoms reversible by rebreathing expired air.

    Area of Science:

    • Psychophysiology
    • Cardiology
    • Neurology

    Background:

    • Hyperventilation syndrome has been researched for over a century, with various historical labels like "soldier's heart" and "anxiety neurosis."
    • Despite similar symptoms, diverse diagnostic labels have led to inconsistent treatment approaches.
    • Symptoms include dyspnea, paresthesia, trembling, tachycardia, and in severe cases, tetany or convulsions.

    Purpose of the Study:

    • To examine the psychophysiological phenomenon of hyperventilation syndrome.
    • To highlight the inconsistencies in diagnostic labels and their impact on treatment.
    • To explore the relationship between hyperventilation and psychomotor performance.

    Main Methods:

    • Review of historical research dating back a century.

    Related Experiment Videos

  • Induction of hyperventilation symptoms through overbreathing and CO2 challenges in susceptible individuals.
  • Reversal of symptoms using rebreathing techniques.

    • Main Results:

    • Hyperventilation, even without apparent cause, can lead to psychomotor decrements and increased errors.
    • Symptoms characteristic of the syndrome can be rapidly induced in sensitive individuals via overbreathing or CO2.
    • Induced symptoms are quickly reversed by rebreathing expired air.

    Conclusions:

    • The historical proliferation of labels for hyperventilation syndrome is problematic due to varied treatments.
    • Certain individuals exhibit heightened sensitivity to overbreathing and CO2 challenges.
    • The syndrome's symptoms can be experimentally reproduced and reversed, underscoring its physiological basis.
