Partial or total obstruction of an endotracheal tube (ETT) by mucus can cause severe respiratory distress, hypoxemia, or death. Signs of an obstructed ETT include increased ventilation pressure, changes in the ventilator graphics, S(pO(2)) decrease, and cardiovascular changes. We present 3 patients whose ETTs were partially obstructed by mucus. In each case the patient displayed adverse effects from the obstruction, but once the obstruction was removed they showed dramatic improvement. In each case we used a new device (Rescue Cath, Omneotech, Tavernier, Florida) designed to remove mucus from the ETT lumen. The 3 cases demonstrate that the device is effective and capable of relieving the adverse effects of ETT mucus obstruction.
气管内导管（ETT）部分或完全被黏液阻塞可导致严重的呼吸困难、低氧血症或死亡。ETT 阻塞的迹象包括通气压力增加、通气机图形改变、血氧饱和度（S(pO(2)))降低和心血管变化。我们介绍了 3 例 ETT 部分被黏液阻塞的患者。在每种情况下，患者都表现出了与阻塞相关的不良反应，但一旦阻塞被清除，他们的情况就会显著改善。在每种情况下，我们都使用了一种新的设备（Rescue Cath，Omneotech，Tavernier，佛罗里达州）来清除 ETT 管腔中的黏液。这 3 个病例表明该设备是有效的，能够缓解 ETT 黏液阻塞的不良反应。
