虽然文献中记录了呼吸速度描记器证明线性输出到静态流量的范围，但尚未研究动态非正弦流量（例如鼻呼吸期间发生的流量）输入所导致的输出可靠性或校准函数的稳定性。此外，还不知道与呼吸速度记录仪结合使用的必要压力传感器的类型是否影响呼吸速度记录仪的线性度、输出可靠性或动态响应。为了提供关于这些点的信息，作者确定了三种常用于肺动脉测压的呼吸速度描记器的动态和静态响应，以及三种必要的压力传感器。实验数据表明：（a）输出可靠性取决于呼吸速度描记器-压力传感器组合，并且不容易从单个组件的可靠性中预测，（B）加热增加了呼吸速度描记器的可靠性，以及（c）高流量频率而非低流量频率的传感器组合之间存在精度差异。< >
Although the ranges in which pneumotachographs evidence linear output to static flows are documented in the literature, output reliability or the stability of calibration functions resulting from the input of dynamic nonsinusoidal flows (such as those which occur during nasal breathing) have not been investigated. Furthermore, it is not known whether the type of requisite pressure transducer used in conjunction with the pneumotachograph influences the pneumotachograph's linearity, output reliability, or dynamic response. To provide information on these points, the authors determined the dynamic and static responsiveness of three pneumotachographs commonly used in rhinomanometry, in combination with three requisite pressure transducers. Experimental data indicate that: (a) output reliability depended on the pneumotachograph-pressure transducer combination and was not readily predictable from the reliabilities of the individual components, (b) heating increased pneumotachograph reliability, and (c) differences in accuracy existed among transducer combinations of high, but not low, flow frequencies.< >
