A new method for continuously and noninvasively monitoring carbon dioxide pressure in the skin tissue using an unheated transcutaneous carbon dioxide sensor is presented. The design, calibration, and principle of operation of the sensor are discussed. The transcutaneous PCO2 sensor was tested in vitro for response time, drift, linearity, and interfering anesthetic gases, all of which showed that the sensor is accurate, reliable, and immune to anesthetic gases. Clinical results using the unheated transcutaneous PCO2 sensor with neonatal patients are presented, verifying the clinical usefulness of the device for noninvasively monitoring trends in arterial PCO2.
提出了一种使用未加热的经皮二氧化碳传感器连续无创监测皮肤组织中二氧化碳压力的新方法。讨论了该传感器的设计、校准和工作原理。对经皮PCO2传感器进行了体外测试，包括响应时间、漂移、线性度和麻醉气体干扰，所有这些都表明该传感器准确、可靠且对麻醉气体免疫。给出了使用未加热的经皮PCO2传感器对新生儿患者的临床结果，验证了该设备用于无创监测动脉PCO2趋势的临床实用性。
