Apneic oxygenation during intubation is the application of oxygen via a nasal cannula, which is left in place throughout laryngoscopy. The flow rate of oxygen is set to at least 15 L/min and theoretically reduces the risk of oxygen desaturation and hypoxemia during the procedure. Over the last 5 years, there have been several studies published on this topic with differing results. Despite conflicting results, use of apneic oxygenation is becoming more prevalent and is being implemented into standard operating procedures in some clinical settings. Because of the low risk of adding a nasal cannula during intubation and the potential benefit of reducing the incidence of hypoxemia and severe oxygen desaturation, it would be prudent to implement apneic oxygenation when available.
插管期间的无呼吸氧合是指通过鼻导管给予氧气，在整个喉镜检查过程中鼻导管一直保留在位。氧气流速设定为至少15升/分钟，理论上可降低该操作过程中氧饱和度降低和低氧血症的风险。在过去5年里，关于这个主题发表了几项研究，结果各不相同。尽管结果相互矛盾，但无呼吸氧合的使用正变得越来越普遍，并且在一些临床环境中已被纳入标准操作程序。由于在插管期间添加鼻导管的风险较低，且有可能降低低氧血症和严重氧饱和度降低的发生率，因此在可行时实施无呼吸氧合是明智的。
