title: [Assessment of parameters of human outside respiration by portative volumeter under field and laboratory conditions].
abstract: The assessment of spirometric possibilities of lung usually happens possible only in laboratory to use of expensive equipment, besides thus it is necessary to use cycle ergometer or racetracks which make the contribution to violation of natural coordination of movements of the person. Thereof there is a desire to develop the portable device, which would measure key parameters of external breath of the person in field conditions with data recording possibility in the memory in a mode of breath-by-breath then to transfer them to the computer for the further analysis. We developed the portable device consisting of the easy and tiny sensor, fastening to a respiratory mask. The sensor incorporates by means of a cable to the tiny device to the liquid crystal screen on which serially at the choice of the operator values of pulmonary ventilation (Ve), volume of an exhalation (Vt) and frequency of breath in a mode of breath-by-breath are deduced. Metrological researches showed that the device error generally didn't exceed 5%.
