Abstract
A method is described for measuring metabolic gas exchange during general anaesthesia using a respiratory mass spectrometer, a mixing box and two inert tracer gases. Measurement of inspired and expired minute volume is possible to within 2%; oxygen consumption, carbon dioxide output and respiratory quotient can be measured to within 10%.
摘要
描述了一种使用呼吸质谱仪、混合箱和两种惰性示踪气体在全身麻醉期间测量代谢气体交换的方法。每分钟吸气量和呼气量的测量误差可控制在2%以内；耗氧量、二氧化碳排出量和呼吸商的测量误差可控制在10%以内。
