Explanation · 中文詳解

機械通氣(Mechanical ventilation)的病人若出現低壓警報(Low-pressure alarm),通常暗示氣道迴路斷開、管路脫落或氣囊(Cuff)洩漏。這意味著病人無法獲得預期的潮氣容積(Tidal volume),可能導致急性缺氧,是危及生命的緊急情況,護理師必須立即檢查並恢復通氣。高壓警報通常與阻塞、分泌物過多或病人與呼吸器不同步(如咳嗽)有關,雖需處理,但通常不如管路脫落急迫。

A low-pressure alarm on a mechanical ventilator indicates a disconnection in the circuit or a cuff leak, which prevents the delivery of tidal volume and poses an immediate life-threatening risk of hypoxia. This requires the nurse to immediately reconnect the tubing or address the leak to restore ventilation.
