動脈血氣分析報告顯示:pH 7.25, PaCO2 55 mmHg, HCO3 24 mEq/L。護理師應如何解讀此結果?

An arterial blood gas (ABG) report shows: pH 7.25, PaCO2 55 mmHg, and HCO3 24 mEq/L. How should the nurse interpret these results?

  • ARespiratory alkalosis
    呼吸性鹼中毒
  • BMetabolic acidosis
    代謝性酸中毒
  • CRespiratory acidosis✓ 正解
    呼吸性酸中毒
  • DMetabolic alkalosis
    代謝性鹼中毒
Explanation · 中文詳解

pH 7.25 低於正常(酸中毒)。PaCO2 55 mmHg 高於正常(二氧化碳堆積),且與 pH 變動方向相反,顯示酸中毒由呼吸系統引起。HCO3 24 mEq/L 在正常範圍內,表示尚未產生代償。此為未代償的呼吸性酸中毒。

A pH of 7.25 is below normal (acidosis). PaCO2 of 55 mmHg is above normal (CO2 retention), and changes in the opposite direction to the pH, indicating that the acidosis is of respiratory origin. HCO3 at 24 mEq/L is within the normal range, indicating that no compensation has yet developed. This represents uncompensated respiratory acidosis.
