OBJECTIVE
To describe clinical usage of the Paratrend 7 continuous arterial blood gas monitor in children.
DESIGN
Children older than 24 months of age who required significant ventilatory intervention were eligible for sensor placement.
INTERVENTIONS
The sensor was placed via the arterial catheter to measure pH, PCO2, PO2, and temperature. The simultaneous arterial blood gas value was recorded along with the sensor reading.
RESULTS
The sensor functioned for as long as seven days and provided the clinicians with data on the patient's respiratory status. The statistical validity of the device when compared to the arterial blood gas showed that the bias/precision for pH was 0.006/0.024, for PCO2 -0.78/4.68 mmHg, and for PO2 1.9%/17.1% (mmHg).
CONCLUSIONS
This report demonstrates actual clinical use of continuous blood gas monitoring in children. The information obtained is a major asset to the management of critically ill children in the intensive care unit.
目的
描述Paratrend 7连续动脉血气监测仪在儿童中的临床应用。
设计
年龄超过24个月且需要进行重大通气干预的儿童有资格进行传感器放置。
干预措施
通过动脉导管放置传感器以测量pH值、二氧化碳分压（PCO2）、氧分压（PO2）和温度。记录同时采集的动脉血气值以及传感器读数。
结果
该传感器可运行长达7天，并为临床医生提供患者呼吸状态的数据。与动脉血气相比，该设备的统计有效性表明，pH值的偏差/精密度为0.006/0.024，PCO2为-0.78/4.68 mmHg，PO2为1.9%/17.1%（mmHg）。
结论
本报告展示了连续血气监测在儿童中的实际临床应用。所获得的信息是重症监护病房中危重症儿童管理的一项重要资产。
