This capacity is reduced when a reduction in filtered bicarbonate occurs, as observed in renal failure, or when enhanced tubular reabsorption of bicarbonate occurs, as observed in volume depletion (see Maintenance of metabolic alkalosis). (medscape.com)

For example, if the increase in PaCO 2 is more than 0.7 times the increase in bicarbonate, then metabolic alkalosis coexists with primary respiratory acidosis. (medscape.com)
Remember that an elevated serum bicarbonate concentration may also be observed as a compensatory response to primary respiratory acidosis. (medscape.com)
Calculation of the serum anion gap may also help to differentiate between primary metabolic alkalosis and metabolic compensation for respiratory acidosis. (medscape.com)

Total leucine carbon entry did not change from the basal value during saline infusion but increased (P less than .01) with acidosis and decreased (P less than .05) with alkalosis. (nih.gov)
During acidosis, total plasma essential and nonessential amino acid concentrations increased (P less than .05), whereas during alkalosis, total plasma essential and nonessential amino acid concentrations decreased (P less than .05). (nih.gov)
Exhalation of large amounts of CO 2 causes respiratory alkalosis in arterial blood (hence on ABG measurements), but poor systemic perfusion and cellular ischemia cause cellular acidosis, leading to acidosis of venous blood. (msdmanuals.com)
Your body compensates for both alkalosis and acidosis mainly through your lungs. (healthline.com)
In patients with metabolic acidosis, it is important to determine if respiratory compensation is adequate or if the patient has a concurrent respiratory acidosis or alkalosis. (medscape.com)
An increase in H+ ion concentration decreases the pH (acidosis) and a reduction in H+ concentration increases the pH (alkalosis). (slideshare.net)
Serious life-threatening symptoms can occur within six hours and include respiratory alkalosis, metabolic acidosis, cerebral edema, and death. (vumc.org)
Low pH is associated with acidosis and high pH with alkalosis [1,2]. (radiometer.com)

These formulations are intended to slow the release of potassium so that the likelihood of a high localized concentration of potassium chloride within the gastrointestinal tract is reduced. (drugs.com)
Potassium depletion due to these causes is usually accompanied by a concomitant loss of chloride and is manifested by hypokalemia and metabolic alkalosis. (drugs.com)
If potassium depletion associated with metabolic alkalosis cannot be managed by correcting the fundamental cause of the deficiency, e.g., where the patient requires long-term diuretic therapy, supplemental potassium in the form of high-potassium food or potassium chloride may be able to restore normal potassium levels.
