Acid-base equilibrium of the blood in circulatory stasis
I) The characteristics of the blood stasis, namely the venous acidosis and the arterial alkalosis, are found in the different kinds of circulatory slowing, whatever be their origin, pathological or experimental. 2) In the course of the stasis the passage of the bicarbonate of the blood towards the t...
