My answer to all these questions is: Use the concentration of titratable hydrogen ion in the extended extracellular fluid (at the actual oxygen saturation), ctHEcf, as the relevant measure of an overall metabolic acidosis or alkalosis, which may be due to several cooperative or counteractive pathophysiological processes. ctHEcf and SBE are numerically equal, with opposite sign, but it is the hy...
During the induction period, especially in the case of cyanotic patients, straining, crying, and fighting should be avoided because they raise the intraalveolar pressure, leading to reduced pulmonary perfusion, increased pulmonary vascular resistance, and hence increased right-to-left shunting with worsening of systemic hypoxia. They also increase intra-thoracic pressure and impede the venous r...
In the 17th century the notion of nutrition and diet changed in northern European countries. First chemical experiments fostered the idea that salts resulted from a union of acids and bases. Digestion was no more regarded as a process of cooking but a succession of fermentations controlled by a balanced production of acids and alkali. Life seemed to depend on the equilibrium of acids and alkali...
influence extracellular acid–base status in brachyuran decapod crustaceans (Truchot, 1973; Truchot, 1981; Truchot, 1992; Mangum et al., 1976; Henry and Cameron, 1982; Wheatly, 1985). Although the underlying mechanisms and the physiological consequences remain unclear, the basis for the relationship between acid–base status and ion regulation can be attributed to the catalysed hydration of CO2 b...
Background Acid-base assessments in hemodialysis patients have been limited almost entirely to measurements of total CO 2 concentration, and assumptions have been made about the presence of acid-base disorders. To gain a fuller understanding of the acid-base status of stable hemodialysis patients, we analyzed measurements of pCO 2 , pH and HCO 3 - obtained in a cohort of chronic stable hemodial...
We undertook the present study to examine the acid-base and electrolyte disturbances in relation to hydration status in patients with diabetic ketoacidosis (DKA). A total of 40 insulin-dependent diabetes mellitus patients (22 male, 18 female), aged 18-61 years with DKA admitted to our hospital during the last 2 years, were studied. The duration of diabetes averaged 9 +/- 2 years. In all cases a...
