[A study of dynamic errors of measuring main respiratory parameters by devices fitted out with variable pressure differential flowmeters].
A method that may be used for identifying the dynamic characteristics of the measuring canal of a device for studying the respiratory parameters is described. The device is equipped with a flow-metering primary transducer of variable pressure differential and a semiconductor pressure transformer of the PDP-10 or PDP-12 types according to the reaction towards graded action. The results of the computation of dynamic errors that may occur in measuring the main parameters of forced expiration by devices of such design are analyzed.
