鼻胃管（Nasogastric tube）給藥或灌食前確認位置是防止吸入性肺炎（Aspiration Pneumonia）的關鍵護理安全措施。根據實證護理準則，抽吸胃內容物並檢測 pH 值是目前床邊最準確的確認方式。若 pH 值小於 5.0，通常表示管路位於胃部。X 光定位（X-ray confirmation）雖為黃金標準，但不可能每次給藥前皆執行，故 pH 測試是臨床最常規的檢查。
Verifying NG tube placement before feeding or medication is essential for preventing aspiration pneumonia. Per evidence-based guidelines, aspirating gastric contents and checking pH is the most accurate bedside method. A pH <5.0 usually indicates gastric placement. X-ray confirmation is the gold standard but not feasible before every dose, so pH testing is the most common clinical check.
