  • Title: [Functional diagnosis of laryngeal and tracheal stenoses].
    Author: Gabathuler M, Bühlmann AA.
    Journal: Schweiz Med Wochenschr; 1976 Mar 06; 106(10):334-9. PubMed ID: 1251148.
    Abstract:
    In 20 patients with upper airway obstruction in the region of the larynx and the extrathoracic and intrathoracic trachea, inspiratory and expiratory resistance, FIV1, FEV1 and total and vital capacity were determined. In patients with obstruction in the larynx and the extrathoracic trachea FIV1 is generally below FEV1. So-called "dynamic" obstruction, depending on flow and direction of flow, leads to a considerable descrepancy between FIV1 and FEV1. Impairment of respiration can be assummed if, in the adult, airway resistance during spontaneous breathing is higher than 6 cm H2O/l/sec during inspiration and/or expiration. After successful surgical correction airway resistance and FIV1 and FEV1 are restored to normal values.
