| 摘 要： | 通过对１８例慢性阻塞性肺病（ＣＯＰＤ）缓解期患者（Ｉ组）和１５例呼衰气管插管患者（ＩＩ组）口腔和气管闭合压（Ｐｍ０．１和ＰＴ０．１）及胸腔压（Ｐｅｓ）的同步测定，显示两组患者吸气后，口腔或气管插管外口压力变化明显落后于胸腔压的变化，其落后时间在Ⅰ组和Ⅱ组分别为８０ｍｓ及１５０ｍｓ。口腔或气道外口出现吸气负压１００ｍｓ时胸腔压的改变（Ｐ０．１ｅｓ）明显高于Ｐｍ０．１或ＰＴ０．１。Ｉ组Ｐｍ０．１与同步胸腔压的改变（ｉｓｏ－ｔｉｍｅＰｅｓ０．１）及吸气后１００ｍｓ胸腔压的改变（Ｐｅｓ０．１）无明显差别，但ＩＩ组ＰＴ０．１比ｉｓｏ－ｔｉｍｅＰｅｓ０．１及Ｐｅｓ０．１均低（Ｐ＜０．０５）。

| Abstract: | Month,tracheal occlusion pressure (pm0.1 or PT0.1) and esophageal pressure (Pe)were recorded simultaneously in 18 stable COPD patients(group I) and 15 intnbated COPD petients (gronp II). The results showed that the mouth and traeheal negative pressure lagged behind the esophageal pressure swing 80 ms and 150ms in group I and group II respectively after inspiring against a closed airway. In fact,Pm0.1 and PT0.1 just reflects the change of pressure in the outer end of the airway at 180 ms and 250 ms respectively after the onset of Pe changes,and were much lower than Pe change during this perlod. Pm0.1 was neariy the same an the iso-time Pes(iso-time Pes0.1) and esophageal pressure at 100ms after the onset of inspiration (Pes0.1) in group I, but PT0.1 in group II was greater than the iso-time Pes0.1 and Pes0.1 |
