肝素治療的目標 aPTT 通常為正常值的 1.5 到 2.5 倍（約 60-80 秒）。當數值達到 95 秒時，代表抗凝血效果過強，有出血風險。首要動作應為停止輸注，以避免藥物持續進入體內引發大出血，隨後再通知醫師調整劑量。給予解毒劑需視出血嚴重程度而定，並非第一步驟。
The therapeutic aPTT range for heparin therapy is typically 1.5 to 2.5 times the control value, approximately 60–80 seconds. An aPTT of 95 seconds indicates excessive anticoagulation and a high risk of bleeding, requiring immediate cessation of the infusion to prevent hemorrhage. Subsequent actions include notifying the provider and administering protamine sulfate only if severe bleeding occurs.
