Eight commercially available soft cuff endotracheal tubes were studied to determine the relationship between inflation pressure distention of the cuff. Although the balloon cuff may be easily distensible in open air, when confined within the trachea small increments in the inflation volume may produce high pressures. This means that continuous external control of cuff pressure is required to prevent ischemia of the tracheal wall. Major tracheal complications in a busy ICU were examined before and after the introduction of a controlled pressure tube. Control of intratracheal cuff pressures decreased major tracheal complications tenfold and eliminated complications specifically related to the cuff.
对8种市售软套囊气管导管进行了研究，以确定套囊充气压力与扩张之间的关系。尽管气囊套囊在空气中可能易于扩张，但当置于气管内时，充气量的微小增加可能会产生高压。这意味着需要对套囊压力进行持续的外部控制，以防止气管壁缺血。在引入可控压力导管前后，对繁忙重症监护病房中的主要气管并发症进行了检查。气管内套囊压力的控制使主要气管并发症减少了十倍，并消除了与套囊具体相关的并发症。
