Abstract:
Procedure of mechanical support of natural respiration and process of an artificial respiration with simultaneous registration of mechanical cardiac action via measurement of electric impedance variation within a region of the throat, breast and/or epigastrium, wherein a course of respiratory gas supply and respiratory gas restore carried out by respiratory apparatus is controlled by a course of a measured impedance curve which allows calculations of systolic discharge of a heart as well as heart minute volume which is, in turn, used to control the respiratory apparatus, whereby to measure the impedance curve:a first current electrode is placed within a region of the right atrium through access via the vena cava or the esophagus or the trachea or another vessel in the mediastinum, and a second external current electrode is placed on the skin of the throat near the arteria carotis or the vena jugularis; and a first measuring electrode is placed within a region of right atrium through access via the vena cava or the esophagus or the trachea or another vessel of the mediastinum and a second external measuring electrode is placed on the skin of the throat within a region of the arteria carotis or vena jugularis, so that the measuring electrodes lie in the current path between the first and second current electrodes, whereby no lung tissue involved with the gas exchange is found on the traction of the measuring electrode.
