病人診斷為急性呼吸窘迫症候群並使用呼吸器，護理師聽到高壓警報器響起。護理師應優先檢查何種最常見的原因？
A client is diagnosed with acute respiratory distress syndrome (ARDS) and is currently ventilated. The nurse notices the high-pressure alarm sounding. What is the most common cause the nurse should investigate?
- AA disconnection in the ventilator circuit呼吸器管路斷裂
- BDecrease in lung compliance肺順應性降低
- CLeak in the endotracheal tube cuff氣管內管氣囊洩漏
- DPatient biting the endotracheal tube✓ 正解病人咬住氣管內管
呼吸器高壓警報通常代表氣道阻力增加，病人咬管、氣管內痰液阻塞或氣管攣縮是最常見原因。A 與 C 均會導致氣體外洩，引發低壓警報。肺順應性下降雖會引起高壓，但臨床上病人咬管或管路扭曲導致的阻力增加更為常見且需立即排除。
A high-pressure alarm on a ventilator typically indicates increased airway resistance, with patient biting the endotracheal tube being a common and immediate cause that nurses should investigate. In contrast, circuit disconnections or cuff leaks usually trigger low-pressure alarms due to gas escape, while decreased lung compliance is less frequently the primary immediate concern compared to mechanical obstructions.
台美在呼吸器照護原則一致，但美國呼吸治療師（RT）責任權限較大，台灣護理師常需第一線處理常見警報。
