摘要

使用气体记录仪测量小型动物的气管流量可能会有问题，因为测量设备的精度和输入阻抗之间存在权衡。在本文中，我们提出了一种计算小型动物气道流动的方法，该方法纯粹从实验通风机的几何形状来计算，而不需要在空气通道中增加任何额外阻力。将该技术在0 ~ 30 Hz频率范围内的性能与适当尺寸的气记录仪进行了定量比较。

Estimating tracheal flow in small animals

The measurement of t rachea l flow in small an imals using pneumotachographs can be problematic, since a tradeoff between precision a n d inpu t impedance of the measurement device i s encountered. In this paper, we present a method of es t imat ing t racheal flow in small an imals purely from the geometry of the experimental ventilator, without a n y additional resistance in t h e air pathway. The performance of t h i s technique in the frequency r ange of 0 t o 30 Hz is compared quantitatively to pneumotachographs of an appropriate size.
