[The value of measurements of oscillatory resistance in the evaluation of lung function. A comparative study in adults and children (author's transl)].
Measurements of total oscillatory impedance (ROS) together with spirometric and body plethysmographic determinations were made in adults and children and the results were compared. In adults (n = 260) correlation was less close (r = 0.53) than it was in 88 children (r = 0.82). Even if ROS was of similar magnitude the phase shift between pressure and flow tended to be more negative than it was in children. These differences are presumably due to anatomical differences between the adult and the growing lung. In interpretation of the results it is suggested that the differences in the ratio: airways compliance/airways resistance reflect changes arising from age and disease processes.
