Age-dependent changes in the complex of impedance plethysmographic and hemodynamic indices of the lung and aorta.
The author has tested 2 groups, each consisting of 30 healthy individuals aged 21-40 and 41-60 years, respectively, by means of IPG records of the lung and aorta. The LIPG has not shown any essential changes with the advance in age, wherease the AIPG showed a decrease of the Q-a interval, as well as the Vmaxt of quick blood filling and of the rheographic systolic index without morphological changes.
