根因分析
呼吸机（如Hamilton C6、Drager Evita V500）的高压报警是患者-呼吸机不同步、气道阻塞或咳嗽的关键安全警报；关闭报警会移除临床医生干预的唯一即时提示，增加气压伤或通气不足风险。
English
High-pressure alarms on ventilators (e.g., Hamilton C6, Drager Evita V500) are critical safety alerts for patient-ventilator asynchrony, airway obstruction, or coughing; disabling them removes the only immediate cue for clinicians to intervene, risking barotrauma or hypoventilation.

-
Implement a structured alarm management protocol: set high-pressure alarm to 10 cmH2O above peak inspiratory pressure (PIP), review settings every 4 hours, and use waveform analysis to distinguish nuisance from true alarms
-
Enable 'alarm escalation' feature on the ventilator (e.g., Hamilton C6 'Smart Alarm') which increases alarm volume after 30 seconds if unacknowledged
-
Use a separate centralized alarm system (e.g., Philips IntelliVue) that filters and prioritizes ventilator alarms based on severity, reducing false positives
无效尝试
常见但无效的做法:
-
65% 失败
Setting threshold too high delays detection of true obstruction; patient may already be in distress before alarm triggers
-
55% 失败
Pause only temporarily silences; repeated use creates habit of ignoring alarms, and asynchrony can occur during pause
-
45% 失败
Pressure-support mode still generates high-pressure alarms during cough or breath-stacking; mode change alone doesn't address alarm fatigue
