Respiratory distress is a common ailment in small animal medicine. Oxygen supplementation is a mainstay of initial therapy. High Flow Nasal Cannula Oxygen Therapy (HFNCOT) has become increasingly popular as a treatment modality in human medicine, and more recently in canine patients. These devices deliver high flow rates of heated and humidified oxygen at an adjustable fraction of inspired oxygen . This article reviews current literature in human patients on HFNCOT as well as studies that have evaluated its use in veterinary patients. A discussion of the respiratory physiology that is associated with respiratory distress, in addition to an overview of currently available oxygen supplementation modalities is provided. The physiologic benefits of HFNCOT are explained, as are technical aspects associated with its use. Recommendations on initial settings, maintenance therapy, and weaning are also described.

呼吸窘迫是小动物医学中常见的疾病。氧气补充是初始治疗的支柱。高流量鼻导管氧疗 (HFNCOT) 作为一种治疗方式在人类医学中越来越受欢迎，最近在犬类患者中也越来越受欢迎。这些设备以可调节的吸入氧气比例提供高流速的加热和加湿氧气。本文回顾了人类患者目前关于 HFNCOT 的文献以及评估其在兽医患者中的应用的研究。除了概述当前可用的氧气补充方式之外，还提供了与呼吸窘迫相关的呼吸生理学的讨论。解释了 HFNCOT 的生理益处，以及与其使用相关的技术方面。
