The search for a reliable and accurate respiratory rate monitor for use in non-intubated patients has proved to be a long and fruitless one. A new device fulfilling the criteria for such a monitor has recently been described. The pyroelectric polymer (PEP) device is safe, non-invasive, and cheap. In this study the PEP device, transthoracic impedance, and standard observer counting were all compared with the existing gold standard of capnography in 12 healthy adult volunteers. Using a standard statistical technique it was shown that the PEP device performed as well as a capnograph and was more accurate than the other currently available methods of monitoring respiratory rate.
事实证明，寻找一种可靠且准确的用于非插管患者的呼吸频率监测仪是一个漫长而无果的过程。最近有人描述了一种符合此类监测仪标准的新设备。热释电聚合物（PEP）设备安全、无创且价格低廉。在本研究中，对12名健康成年志愿者的热释电聚合物设备、经胸阻抗和标准观察者计数与现有的二氧化碳描记法金标准进行了比较。使用标准统计技术表明，热释电聚合物设备的表现与二氧化碳描记仪相当，并且比目前其他可用的呼吸频率监测方法更准确。
