Brachycephalic airway syndrome can pose a risk of complicated recovery from anesthesia as a result of irritation to the excess pharyngeal andlaryngeal tissue present in affected dogs. High‐flow nasal cannula (HFNC) oxygen therapy is a respiratory support modality that offers provision of continuous positive airway pressure via high gas flow rates. The HFNC system actively warms and humidifies inspired gases, which improves comfort and facilitates tolerance of the high flow rates in people and dogs. HFNC oxygen therapy was applied to brachycephalic dogs that developed increased work of breathing or hypoxemia in the recovery phase of anesthesia to determine if this device would be tolerable and effective for relief of upper respiratory difficulty.

阻塞性上呼吸道呼吸的狗从全身麻醉恢复过程中使用高流量鼻插管氧疗法的初步评估。

由于患病犬中存在过多的咽部和喉部组织而受到刺激，导致短头气道综合征可能会导致复杂的麻醉恢复风险。高流量鼻插管（HFNC）氧气疗法是一种呼吸支持方式，可通过高气体流量提供持续的气道正压。HFNC系统可主动加热和加湿所吸入的气体，从而提高舒适度并有助于耐受人和狗的高流速。HFNC氧气疗法应用于在麻醉恢复阶段呼吸或低氧血症增加的近脑狗，以确定该设备是否可以耐受并有效缓解上呼吸道疾病。
