各位医学界的版友们好 我目前是个研究生 写有关医学方面的专利论文 因此想请教一件医学的技术问题 Method for determining airway pressure levels at which certain lung conditions of a lung ventilated by an artificial ventilator occur, comprising the steps of: a) obtaining data samples of the CO2 concentration of the expired gas over a single breath, b) selecting a plurality of data samples from said obtained data samples, c) calculating a mean tracing value being sensitive to changes of alveolar dead space on the basis of said selected data samples, d) repeating steps a), b) and c) for obtaining a plurality of mean tracing values, and e) changing the airway pressure of the artificial ventilator, wherein from the observation of the resulting course of the plurality of calculated mean tracing values the airway pressure level at which alveolar opening or lung overdistension or lung open condition or alveolar closing occurs is detected." 根据这个内容，我觉得这是一项「依据肺部状况以决定气道压力位准之方法， 藉由人工呼吸器来进行这项方法」 可以麻烦各专家，大略跟我讲一下技术的内容就好 像是他是怎麽操作，或是哪里有网路资料给我大概了解就好 谢谢 --
