The nasal cannula is widely regarded as a safe and effective means of administering low- and high-flow oxygen to patients irrespective of their age. However, variability in delivered oxygen concentration (F_DO2 ) via nasal cannula has the potential to pose health risks. The present study aimed to evaluate predictive equations for F_DO2 over a large parameter space, including variation in breathing, oxygen flow, and upper-airway geometry representative of both young children and adults.

在婴儿和成人气道复制品中评估鼻插管的高流量和低流量氧气输送。

鼻插管被广泛认为是向患者提供低流量和高流量氧气的安全有效的方法，无论其年龄如何。然而，通过鼻插管输送的氧气浓度 (F _{DO 2} ) 的变化可能会带来健康风险。本研究旨在评估大参数空间上的F _{DO 2预测方程，包括代表幼儿和成人的呼吸、氧流量和上呼吸道几何形状的变化。}
