[Choice of efficient dimensions of constricting devices for tachospirometric transducers].

The author provides evidence for the choice of the efficient dimensions of tachospirometric transducers for the volumetric blood flow velocity fitted out with a membrane restriction. The increase of the output signal of the transducer with a permissible resistance to respiration is viewed as a criterion for the efficiency. The improvement of the metrological, physiological and dynamic characteristics of the tachospirometric equipment attained by means of the suggested method is demonstrated.
