手术室中呼吸和麻醉气体的监测对于患者安全非常重要。本研究测量了使用拉曼光散射的多气体监测仪器的准确度和响应时间。将氧气、二氧化碳、氮气、一氧化二氮、氟烷、安氟醚和异氟醚浓度的测量值与气体混合器标准品和红外麻醉剂分析仪的测量值进行比较。相关系数均大于0.999，气体的可能误差小于0.43体积%，挥发性麻醉剂的可能误差小于0.03体积%。响应时间为67 ms，样品流速为150 ml/min。氮气和一氧化二氮之间以及挥发性麻醉剂之间存在一些信号重叠。这种重叠可以通过线性矩阵分析来补偿。该拉曼仪器承诺监测能力相当于质谱仪，并应证明有吸引力的监测呼吸和麻醉气体在手术室。
The monitoring of respiratory and anesthetic gases in the operating room is important for patient safety. This study measured the accuracy and response time of a multiplegas monitoring instrument that uses Raman light scattering. Measurements of oxygen, carbon dioxide, nitrogen, nitrous oxide, halothane, enflurane, and isoflurane concentrations were compared with a gas mixer standard and with measurements made with an infrared anesthetic agent analyzer. Correlation coefficients were all greater than 0.999, and probable errors were less than 0.43 vol% for the gases and less than 0.03 vol% for the volatile anesthetics. Response time was 67 ms with a sample flow rate of 150 ml/min. There was some signal overlap between nitrogen and nitrous oxide and between the volatile anesthetic agents. Such overlap can be compensated for by linear matrix analysis. The Raman instrument promises a monitoring capability equivalent to the mass spectrometer and should prove attractive for the monitoring of respiratory and anesthetic gases in the operating room.
