DESCRIPTION (provided by applicant): This SBIR program will develop a disposable CO2 sensor for use in emergency resuscitation situations. The sensor will monitor the efficacy of such treatment in real-time. The sensor would connect to a small, non-disposable electronic readout. Existing instrumentation is a colorimetric paper that is large, can be used only for a limited time, and only gives a qualitative readout. The proposed device is very small and non-intrusive, can be used for an extended period of time, and would have a high accuracy quantitative readout. It could be adopted to replace larger, more expensive equipment now used in critical care areas. Sensor operating principals are based upon non-dispersive infrared spectroscopy. Using a reference signal to subtract effects of water droplets, dust, and other noise, the sensor can measure vapor concentrations to better than 10 parts per million accuracy. The light source and detector are fabricated by microelectromechanical systems technology, or MEMS, and can operate at high speed to measure concentration of CO2 versus time in a single breath.

描述（由申请人提供）：该SBIR计划将开发一个用于紧急复苏情况的一次性二氧化碳传感器。传感器将实时监测此类治疗的功效。传感器将连接到一个不可识别的电子读数。现有的仪器是一张大量纸，只能在有限的时间内使用，并且仅提供定性读数。所提出的设备非常小且无侵入性，可以长时间使用，并且具有很高的精度定量读数。可以采用它来代替现在在重症监护区中使用的更大，更昂贵的设备。传感器操作主体基于非分散红外光谱法。使用参考信号减去水滴，灰尘和其他噪声的影响，传感器可以测量蒸气浓度，比每百万个精度的10份大于10份。光源和检测器是通过微电机械系统技术或MEMS制造的，可以高速运行以测量二氧化碳的浓度与时间。
