When pneumotachography is used during intermittent positive pressure ventilation (IPPV), the design of some differential pressure transducers can cause measurement errors. These errors may be avoided by using differential pressure transducers which have small, equal chambers free from temperature sensitive electrical elements. Few of the transducers which are sensitive enough for clinical use fulfil these requirements.
在间歇正压通气（IPPV）过程中使用呼吸流速描记法时，一些差压传感器的设计可能会导致测量误差。通过使用具有小的、相等的腔室且没有温度敏感电子元件的差压传感器，可以避免这些误差。对临床使用足够敏感的传感器中，很少有能满足这些要求的。
