Twenty ICU patients were monitored for an average of 45 hr each, with both bedside and nursing station monitors, which were set to alarm audibly if the patient's oxygen saturation dropped below 90%. Bedside alarms alerted caregivers to 51 of the 74 hypoxemic events; central alarms alerted personnel to the other 23 events. The alarms led to a change in treatment in 35 of the 48 (73%) true desaturation episodes. We conclude that central oximetric monitoring may help with detection of arterial desaturation events even in a well-staffed ICU.
对20名重症监护病房患者平均每人进行了45小时的监测，同时使用床边和护士站监护仪，若患者血氧饱和度降至90%以下，监护仪会发出声音警报。床边警报提示护理人员注意到74次低氧血症事件中的51次；中央警报提示工作人员注意到另外23次事件。在48次（73%）真正的血氧饱和度下降事件中，警报导致了35次治疗的改变。我们得出结论，即使在人员配备充足的重症监护病房，中央血氧饱和度监测也可能有助于检测动脉血氧饱和度下降事件。
