The invention relates to a nasal cannula (1) for high-flow ventilation, wherein the nasal cannula (1) has a base body (2) with a cavity (20), a hose attachment element (6) for connecting a hose (7) tothe cavity (20) for fluidic communication, and a first and a second nose tube (3, 4) pointing away from the base body and serving to connect a respective nostril to the cavity (20) for fluidic communication, wherein the first nose tube (3) has a different flow resistance than the second nose tube (4). The invention makes available a nasal cannula (1) which is easy to produce and to clean and which avoids eddies of the respiratory gas stream in the base body (2) or avoids blockages. 本发明涉及一种用于高流量人工呼吸的鼻插管（1），其中所述鼻插管（1）具有：带有空腔（20）的基体（2）；用于将软管（7）与所述空腔（20）流体连通地连接起来的软管连接元件（6）；以及远离所述基体指向的、用于分别将一个鼻孔与所述空腔（20）流体连通地连接起来的第一和第二鼻管（3、4），其中所述第一鼻管（3）具有与所述第二鼻管（4）不同的流动阻力。用本发明来提供一种鼻插管（1），该鼻插管可以容易地制造并且清洁并且避免了所述基体（2）中的呼吸气流的涡流或者堵塞。
