[Optimal correlations of design parameters and metrological characteristics of piston spirometers].
Sensitivity parameters, the threshold of response and shift pressure for "rolling-seal" spirometers reach the optimum according to the criterion for minimizing the weight of its moving parts. As the result of this, essential reserves of the design can be used, which permits one to substantially improve the methodological and metrological conditions of lung functional tests.
