Increasing the informativeness of pulmonograms

Measurements based on pulmonograms obtained using radio waves record differences in the dynamics of filling of the lungs with air during each respiratory cycle. We report here a solution to the problem of determining the minimum number of respiratory cycles needed in pulmonogram measurements sufficient to obtain reliable data on measures of the functioning of the bronchopulmonary system. Recording of eight consecutive respiratory cycles was found to be sufficient to obtain reliable data.
