Archives of Internal Medicine, 1984 To the Editor .—In their editorial in the November 1983Archives, Garfinkel and Gelfman 1 stated that there is "widespread" uncertainty about what total CO 2 content actually is" and that "CO 2 (from total CO 2 content)... is often confused in the clinician's mind with Pco 2 ." They submit that using the terms bicarbonate concentration or bicarbonate ...

Bicarbonate and the regulation of ventilation
The American Journal of Medicine, 1974Abstract The regulation of ventilation involves a multifactorial control system with several feedback loops transmitting deviations from normal in pH, carbon dioxide tension (pCO 2 ) and oxygen tension (pO 2 ) to the control area. Variations in the size of the bicarbonate pool, caused by ventilatory or metabolic disturbances, can be expected to modify

Advantages of Bicarbonate Hemodialysis
Artificial Organs, 1982ABSTRACTSix patients with frequent episodes of symptomatic hypotension during acetate dialysis were treated with bicarbonate dialysis. In all patients blood pressure, heart rate, and arterial acid‐base values were measured every 30 minutes during each of the five treatments with acetate dialysis and bicarbonate dialysis.

Update on the bicarbonate Hypothesis
1993A single chemoreceptor fibre is excited by both hypoxia and hypercapnia. The bicarbonate hypothesis provides an explanation of how CO2 and O2 converge to give impulses in the same chemoreceptor fibre. Many other explanations are conceivable (R.W. Torrance, 1977), but no other has been put out in the same detail as the bicarbonate one.

CAPD with Bicarbonate Solution
1989One of the major results achieved with CAPD is the good correction of metabolic acidosis and the maintenance of a satisfactory acid-base status. This fact is confirmed by an average plasma bicarbonate concentration in patients on CAPD ranging between 22 and 25 mMol/l.

Fluids, Electrolytes, and Bicarbonate
Veterinary Clinics of North America: Equine Practice, 1993In an attempt to enhance performance, primarily by delaying the onset of fatigue, a variety of formulations of fluids, electrolytes, and sodium bicarbonate are administered to performance horses. Some current practices of fluid and electrolyte supplementation are well justified; others have no basis to support their use.

The Sodium Bicarbonate Controversy
Dimensions Of Critical Care Nursing, 1990Sodium bicarbonate has been deleted from the advanced cardiac life support protocol. Sodium bicarbonate is no longer endorsed as the method of choice for the management of metabolic acidosis in the early rounds of cardiopulmonary resuscitation. This paper discusses mechanisms of acidosis occurring during cardiopulmonary arrest, past and present ...

Bicarbonate transport proteins
Biochemistry and Cell Biology, 2002Bicarbonate is not freely permeable to membranes. Yet, bicarbonate must be moved across membranes, as part of CO2metabolism and to regulate cell pH. Mammalian cells ubiquitously express bicarbonate transport proteins to facilitate the transmembrane bicarbonate flux.

Sucralfate and Gastric Bicarbonate
Pharmacology, 1985The effect of sucralfate treatment (3 g daily for 6 weeks) on gastric HCO3- secretion was investigated in 15 duodenal ulcer patients. After treatment a highly significant (p less than 0.01) increase in gastric bicarbonate output was found. It is suggested that the mode of action of sucralfate includes stimulation of gastric alkaline secretion.

To the Editor. —I read with dismay the recommendations and conclusions of Brashear et al in their article entitled "Relationship Between Arterial and Venous Bicarbonate Values" in theArchives(139:440-442,1979), which are totally at odds with their data and reasonable clinical practice.
