各位醫學界的版友們好 我目前是個研究生 寫有關醫學方面的專利論文 因此想請教一件醫學的技術問題 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." 根據這個內容，我覺得這是一項「依據肺部狀況以決定氣道壓力位準之方法， 藉由人工呼吸器來進行這項方法」 可以麻煩各專家，大略跟我講一下技術的內容就好 像是他是怎麼操作，或是哪裡有網路資料給我大概瞭解就好 謝謝 --
