ELECTROLYTES AND ACID-BASE BALANCE IN HYPOTHERMIA
Survey of Anesthesiology, 1956Dogs were cooled in an ice-water bath, and plasma electrolytes were measured at heart temperatures of 38°C, 28°C and 25°C. A ‘cold acidosis’ occurred during hypothermia that is attributable largely to temperature-influenced physico-chemical factors related to the buffer systems.

Acid-base balance in heart failure
Journal of Nephrology, 2006Abstract: In end-stage heart failure, various acid-base disorders can be discovered due to the renal loss of hydrogenions and hydrogen ion movements into cells, the reduction of the effective circulating volume, hypoxemia and renal failure. This justifies the occurrence of metabolic alkalosis, metabolic acidosis, respiratory alkalosis,

Disorders of Acid-Base Balance
Pediatric Clinics of North America, 1990Acid-base disorders are common in sick children. This article is a practical guide to the differential diagnosis and treatment of simple and mixed acid-base disorders of children. Special attention is given to fundamentals of acid-base physiology, to clinical use of the Henderson equation, and to interpretation of readily available laboratory tests.

The Kidney in Acid-Base Balance
Archives of Internal Medicine, 1965Introduction SUDDEN CHANGES in body acid-base balance are neutralized by the blood buffers within seconds. The lungs partially compensate for acidosis or alkalosis through increased or decreased excretion of CO2in a matter of minutes. The kidneys, however, are ultimately responsible for maintaining body pH within narrow limits.

The American Journal of Nursing, 1975
the chemical reactions of body fluids become too acid or too alkaline. An acid, a substance that contains hydrogen ions that can be given off or donated to other substances, is called a proton donor. A base can receive a hydrogen ion and is a proton acceptor.

The physiological assessment of acid-base balance
British Journal of Diseases of the Chest, 1975Acid-base terminology including the sue of SI units is reviewed. The historical reasons why nomograms have been particularly used in acid-base work are discussed. The theoretical basis of the Henderson-Hasselbalch equation is considered. It is emphasized that the solubility of CO2 in plasma and the apparent first dissociation constant of carbonic acid ...

Respiratory care clinics of North America, 1998
This article emphasizes the interactions between the respiratory and metabolic sources of acid and their clearance. It includes the chemistry of acid-based balance as expressed by the Henderson-Hasselbach equation, the principles and importance of biologic buffering systems, and a brief review of renal regulation of acid-based balance.

The essence of the physical chemical approach to acid–base balance is the understanding that there are three variables that are essential in determining blood pH: partial pressure of CO2, strong ion difference (SID), and total weak acid concentration (ATOT). Neither H+ nor HCO3 − can change unless one or more of these three variables change.

This chapter explains how the body continually produces CO2 and non-volatile acids as a result of metabolic activity. The chapter refers to the blood hydrogen ion concentration [H+] which is normally maintained within the relatively narrow range of 40-45 nmol of free hydrogen ions per litre.
