[Measurement of volume-rate parameters of pulmonary ventilation in infants using the SAV pneumotachograph].

The paper deals with methods and equipment for measuring pulmonary ventilation parameters in children of the lowest age category. Description and substantiation of the given method of the measurement itself on the Pneumotachograph SAV. Evaluation of the obtained results in the records and of the time courses of volume and air flow rate on a single-pen recorder is presented further the relations necessary for quantitative description of analogue signal processing from the pneumotachograph are given as well as the series of parameters obtained on examining 21 infants and their clinical evaluation. (Tab.1,Fig.2,Ref.7.).
