PCA（Patient-Controlled Analgesia）幫浦允許病人自我控制止痛藥物劑量，核心風險在於過度給藥導致呼吸抑制。護理師必須嚴密監測呼吸頻率、深度與鎮靜程度（Sedation scale）。呼吸抑制往往先於意識改變出現，因此定時評估呼吸狀態是 PCA 管理中最優先的護理活動，以確保病人安全。
Respiratory status and sedation level are the highest priorities because opioid analgesics carry a significant risk of respiratory depression. Frequent monitoring allows for early detection of overdose or adverse effects, ensuring patient safety during patient-controlled analgesia.
