The measurement of volatile anaesthetic agents by infrared absorption is liable to interference by other gases which absorb infrared light. In particular, nitrous oxide may, in principle, interfere with the measurement of desflurane. On the other hand, the refractometer should be immune to such effects. We demonstrated that interactions may occur between desflurane and nitrous oxide with some gas analysers and that the refractometer remains a useful instrument.
通过红外吸收测量挥发性麻醉剂容易受到其他吸收红外光的气体的干扰。特别是，一氧化二氮原则上可能会干扰地氟烷的测量。另一方面，折射仪应不受此类影响。我们证明，地氟烷和一氧化二氮之间可能会与一些气体分析仪发生相互作用，并且折射仪仍然是一种有用的仪器。
