The Paratrend 7 sensor is a continuous intravascular blood gas sensor that consists of a miniaturized Clark-type PO2 electrode, fibreoptic pH and PCO2 optodes and a thermocouple, the monitor continuously displays the measured pH, PaO2 PaCO2 and temperature of the blood, and the calculated oxygen saturation, BE and SBC. After 7 years of caring for over 200 patients following insertion of the sensor, we describe our nursing experience with particular emphasis on the adequate fixation of the cannula, sensor system and connectors. The maintenance of the sensor through adequate flushing of the arterial line and care of the insertion site is described. Also outlined are the potential advantages to nursing practice of this new monitoring system, with particular reference to early warning of deterioration in respiratory function, closer control of mechanical ventilation and reduction in blood gas sampling and the errors inherent therein.
Paratrend 7传感器是一种连续血管内血气传感器，它由一个小型化的Clark型PO2电极、光纤pH和PCO2光极以及一个热电偶组成，该监护仪能持续显示所测血液的pH、PaO2、PaCO2和温度，以及计算得出的氧饱和度、碱剩余和标准碳酸氢盐。在使用该传感器对200多名患者进行了7年的护理后，我们描述了我们的护理经验，特别强调了对套管、传感器系统和连接器的妥善固定。还介绍了通过充分冲洗动脉管路和护理穿刺部位来维护传感器的方法。此外，还概述了这种新监测系统在护理实践中的潜在优势，特别是在呼吸功能恶化的早期预警、机械通气的更严密控制以及减少血气采样及其固有误差方面。
