Experiments on visualization of helical counterflow motion of gas mediums in respiratory system

In this paper, some results of clinical and experimental investigations of the biomechanics of pulmonary ventilation are presented. Direct visualization of the motion of non-homogenous gas media in the human respiratory system during inspiration has been obtained for the first time. The existence of the phenomenon of formation of a helical counterflow of gas media at pulmonary ventilation has been proved experimentally. The results obtained can serve as a basis for the development of new methods of controlled respiration and special apparatuses for use in clinical medicine: anesthesiology, resuscitation, and intensive care.
