[The effect of the oxygen content of the air breathed in on the passive electrical properties of muscle tissue].

Abstract

Due to a want of oxygen in the breathing air there appears a change of the volume of muscle cells, of ion concentrations inside and outside the cells as well as disturbances the structure and membrane potential. These changes are connected with changes of the passive electrical properties of the muscle tissue. Measuring the electrical impedance of the muscle it is possible to diagnose alterations as shock and disorder of microcirculation in an easy way continuously. Investigations with rats show that a decrease of the oxygen content in the inspiration air effects characteristic changes in muscle impedance. These changes are reversible in normoxia.
