NG 位置確定的金標準是 X 光。pH < 5.5 代表胃液（酸性），顏色常為混濁綠色。若吸出清澈黃色液體（常為腸液或膽汁）或出現呼吸窘迫、無法說話，則需警惕導管誤入肺部。說話正常不能作為位置正確的判斷依據。
Correct nasogastric tube placement is confirmed by a chest or abdominal X-ray, which is the gold standard, and by aspirating gastric contents with a pH less than 5.5. Gastric aspirate typically appears cloudy and greenish-brown, whereas clear yellow fluid may indicate intestinal placement or reflux.
