尽管呼吸气速度描记器对静态气流表现线性输出的范围在文献中已被证实,但是对于由动态非正弦气流(如发生在鼻腔呼吸中的)的输入导致的输出的可靠性或校准函数的稳定性则尚未研究,而且,我们尚不知道连接呼吸气速度描记器一起使用的必不可少的压力传感器的类型是否会影响呼吸气体速度描记器的线性度、输出可靠性或动态响应。为了提供这些方面的信息,我们确定了连同三个必要的压力传感器在内的三个通常用于鼻压测量中的呼吸气速度描记器的动态与静态响应性。一般地说,a)输出的可靠性依赖于呼吸气速度描记器和压力传感器的连接,不容易从单个成分的可靠性来推测;b)加热可以提
Although the range of linear output of a breath gasograph to static gas flow has been demonstrated in the literature, the reliability of the output or the stability of the calibration function for input by a dynamic non-sinusoidal gas flow (as occurs in nasal breathing) Sex has not been studied yet and we do not yet know whether the type of pressure sensor that is essential for use with a linked pneumotachograph will affect the linearity, output reliability or dynamic response of the respirogram. In order to provide information on these aspects, we determined the dynamic and static response of the three commonly used breath-gas chromatographs in conjunction with three essential pressure sensors. In general, a) the reliability of the output depends on the connection of the pneumotachograph to the pressure sensor and is not easily assumed from the reliability of the individual components; b)
