Pressure transducers are being used with increasing frequency in patient care. The recent availability of sterile transducer domes containing a diaphragm provides a means for reducing the risk of bacteremia when using these devices. The present studies measured the effect of diaphragm domes on the accuracy of pressure measurement. The sensitivity and frequency responses of 5 pressure transducers utilizing diaphragm and nondiaphragm domes were compared. The results indicate that the type of dome utilized and the method of dome application can significantly modify pressure transducer performance. The data are useful in providing optimal accuracy and reliability of pressure measurments when using a diaphragm dome, pressure transducer combination.
压力传感器在患者护理中的使用频率越来越高。最近出现的带有隔膜的无菌传感器圆顶为使用这些设备时降低菌血症风险提供了一种方法。本研究测量了隔膜圆顶对压力测量准确性的影响。比较了5个使用隔膜和非隔膜圆顶的压力传感器的灵敏度和频率响应。结果表明，所使用的圆顶类型和圆顶应用方法可显著改变压力传感器的性能。这些数据有助于在使用隔膜圆顶与压力传感器组合时提供压力测量的最佳准确性和可靠性。
