[Reproducibility of the flow-volume indices of healthy persons and patients with lung diseases].
Reproducibility of the flow-volume indicators at forced expiration and inspiration was calculated during examination of 210 healthy subjects and 420 patients with different pulmonary diseases. Reproducibility of the flow-volume indicators of the median and end part of the forced expiration which reflect largely the function proper of the patency of the distal parts of the bronchial tree was essentially higher in patients and tended toward increase with a rise in the degree of ventilation abnormalities. Reproducibility of the conventional spirographic parameters in healthy subjects and patients with ERF abnormalities did not differ whatever their character and degree.
