Plasma potassium response to acute respiratory alkalosis

Metabolic alkalosis contributes to acute hypercapnic respiratory failure in adult cystic fibrosis.

BACKGROUND and study objectives: Patients with end-stage cystic fibrosis (CF) develop respiratory failure and hypercapnia. In contrast to COPD patients, altered electrolyte transport and malnutrition in CF patients may predispose them to metabolic alkalosis and, therefore, may contribute to hypercapnia. The aim of this study was to determine the prevalence of metabolic alkalosis in adults with ...

Postoperative potassium deficit and metabolic alkalosis.

The respiratory response to chronic metabolic alkalosis and acidosis in disease.

1. The respiratory response to chronic metabolic alkalosis was defined on the basis of 182 determinations of the arterial blood pH, Pco,, HCO,concentration and Po, obtained in thirty uraemic patients undergoing chronic haemodialysis. Plasma bicarbonate concentrations, [HC03 -1, ranged from 20 to 38 mmol/l before dialysis, and were elevated by increasing the acetate content of the dialysate. 2. ...

Response to mercurial diuretics during alkalosis: a comparison of acute metabolic and chronic hypokalemic alkalosis in the dog.

A relationship between the action of mercurial diuretics and acid-base metabolism has been established for many years. Diuresis may be augmented by the administration of acidifying salts such as ammonium chloride (1), and may be decreased or even totally inhibited by alkalinizing agents (2, 3). Although a variety of clinical and experimental studies suggest that the mercurials act by decreasing...

Respiratory alkalosis with especial reference to chest pain.

Respiratory alkalosis may be defined as a state of altered physiochemical processes due to the excessive loss of carbon dioxide through overbreathing. Though this condition is usually referred to as the hyperventilation syndrome, respiratory alkalosis would be more accurate terminology as hyperventilation may occur as a necessary physiologic requirement without producing an alkalotic state.
