The authors studied the effects of nitrous oxide diffusion, using a tracheal model, on the pressure of several endotracheal tube cuffs. Studies carried out showed an increase in volume and pressure of the cuffs related to time exposure and nitrous oxide concentrations used. Use of a self-controlled pressure cuff or filling the cuff with inspired gas composition should be of value to counteract or to prevent the diffusion effect.
作者使用气管模型研究了一氧化二氮扩散对几种气管导管套囊压力的影响。开展的研究表明，套囊的体积和压力会随着暴露时间和所用一氧化二氮浓度的增加而增大。使用自控压力套囊或向套囊内充入吸入气体成分可能有助于抵消或预防扩散效应。
