Blood gas results are pH 7.48, pCO2 30 mmHg, and bicarbonate 22 mmol per liter. How should these results be interpreted?
1Metabolic alkalosis with respiratory compensation
2Respiratory acidosis
3Uncompensated respiratory alkalosis✓ 정답
4Fully compensated metabolic acidosis

Work through the values in order. The pH above 7.45 indicates alkalemia. The carbon dioxide tension is decreased, and that direction matches the alkalemia, so the disorder is respiratory. Bicarbonate is still within the reference range, meaning compensation has not begun. This is an uncompensated respiratory alkalosis.
