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）：这个SBIR项目将开发一种用于紧急复苏情况的一次性二氧化碳传感器。传感器将实时监测这种治疗的效果。传感器将连接到一个小型的，非一次性的电子读出器。现有的仪器是一种比色纸，它很大，只能在有限的时间内使用，并且只能给出定性的读数。所提出的设备非常小且非侵入性，可以长时间使用，并且具有高精度的定量读数。它可以用来取代目前在重症监护领域使用的更大、更昂贵的设备。传感器工作原理基于非色散红外光谱。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，精度优于百万分之十。光源和探测器由微机电系统技术（MEMS）制造，可以高速运行，以测量单次呼吸中的二氧化碳浓度与时间的关系。
