Several oxygen regulators were quantitatively assessed during interface with dynamic respiratory simulation and human user breathing. Continuous measurements of regulator flow, delivered pressure, and delivered oxygenation was provided during variable tidal volumes and breathing frequencies as accomplished initially with breathing simulation and subsequently with human users. The regulators demonstrated large sensitivity to flow demand and the characteristics of the inspiratory flow pulse. Large variations in outlet suction pressure and delivered oxygen concentration accompanied the variable breathing modes of human subjects. The inability of oxygen regulators to consistently provide required oxygen/air delivery is discussed with respect ot inadequate performance specifications currently used.
在与动态呼吸模拟和人类使用者呼吸进行交互的过程中，对几种氧气调节器进行了定量评估。在模拟呼吸以及随后的人类使用者实验中，在不同潮气量和呼吸频率下，持续测量了调节器的流量、输出压力和输氧量。这些调节器对流量需求和吸气流量脉冲特性表现出高度敏感性。随着人类受试者呼吸模式的变化，出口抽吸压力和输氧浓度也出现了很大差异。针对目前使用的性能规格不足的问题，讨论了氧气调节器无法始终如一地提供所需氧气/空气输送量的情况。
