Transtracheal oxygen (TTO) delivery for patients with chronic hypoxemia has been used increasingly since its introduction in 1982. Most complications have been relatively minor and usually occur in conjunction with catheter placement. This report describes two patients with long-term catheter use who developed increasing respiratory failure and cor pulmonale, at least in part, due to a large tracheal mucus plug.
自1982年经气管给氧（TTO）用于慢性低氧血症患者以来，其应用越来越广泛。大多数并发症相对较轻，通常与导管置入有关。本报告描述了两名长期使用导管的患者，他们出现了进行性呼吸衰竭和肺心病，至少部分原因是气管内形成了巨大的黏液栓。
