1 Unaudited Financial Results for the Quarter ended 31st March, 2015 along with Limited Review Report. 2  Date: 14th May, 2015.
The ABG values one would see with respiratory alkalosis would be: pH > 7.45; PaCO2 < 35 mm Hg; and HCO3 < 22 mEq/L if compensating. In acute respiratory alkalosis the compensation is to lower the serum HCO3 by 2 mEq/L for every 10 mmHg reduction in PaCO2.
Loss of gastric acid (vomiting, NG drainage) and diuretic use account for 90% of clinical cases of metabolic alkalosis. Gastric alkalosis is most marked with vomiting due to pyloric stenosis or obstruction because the vomitus is acidic gastric juice only.Vomiting in other conditions may involve a mixture of acid gastric loss and alkaline duodenal contents and the acid-base situation that results is more variable.istamine H2-blockers also decrease gastric H + losses despite continued vomiting or nasogastric drainage and alkalosis will not occur if the fluid lost is not particularly acidic-indeed loss of alkaline small intestinal contents can even result in an acidosis if gastric acid secretion is suppressed.
