I.v. administration of disodium salt of the ethylenediamine tetra-acetic acid to continuously immersed white rats intensified the rats' amplitude and rate of the respiration movement. I.v. administration of calcium chloride to the cooled rats diminished by 11.3% the respiration movement amplitude and by 20.7%--the muscles electrical activity. The findings confirm important role of the calcium ions in infringement of physiological functions under conditions of hypothermia.
