The ejector flowmeter is constructed for continuous removal of excess gas from anaesthetic circuits. This instrument can be used as an air/oxygen mixing device for high-flow humidification systems in wards where compressed air is not available. Pure oxygen is used as driving gas through the ejector. A nomogram has been constructed to show the relationship between oxygen driving pressure, inlet of air to the flowmeter, FIO2 and total outflow.
喷射流量计用于持续排出麻醉回路中的多余气体。该仪器可用作病房中无压缩空气时高流量加湿系统的空气/氧气混合装置。纯氧用作通过喷射器的驱动气体。已绘制列线图以显示氧气驱动压力、流量计空气入口、吸入氧浓度（FIO₂）和总流出量之间的关系。
