As part of a study of the structural-functional correlations of excised human lungs obtained
at autopsy, the parenchyma and peripheral airways were examined by means of …

The impulse oscillation system (IOS) has been developed recently to measure respiratory
system resistance (R rs ) and reactance (X rs ) at different frequencies up to ≥25 Hz. IOS has, …

Senile lungs are characterized by a homogeneous enlargement of the alveolar airspaces,
without fibrosis or destruction of their walls. Study of the functional characteristics of excised …

Partitioning of pulmonary resistance of 15 excised human and 5 canine lungs by means of a
retrograde catheter demonstrated that the share of peripheral airways (with an ID of 2.4 mm …

The breathing pattern of 399 patients with hyperventilation syndrome (HVS) and/or with anxiety
disorders and that of 347 normal controls was investigated during a 5 min period of quiet …

In 54 patients with interstitial lung diseases and no signs of airway obstruction we measured
lung volumes, maximal expiratory flows, diffusing capacity (DLCO), total respiratory …

Ankylosing spondylitis and kyphoscoliosis both alter the function of the lung by modifying the
mechanical properties of the thoracic cage. The purpose of the present study was to assess …

Because of the contradictory statements published about the influence of the shunt properties
of the upper airway on the measurements of the respiratory impedence by means of the …

This study was designed to test whether awareness of the measurement of breathing influences
the breathing pattern in healthy subjects under routine laboratory conditions. Seventy …

The forced oscillation technique used to determine the impedance of the respiratory system
has been modified by measuring, instead of pressure and airflow at the mouth of the subject, …
