| A method of olfactometry is proposed, allowing to connect the parameters of respiration with the parameters of the olfactory function to ensure an increase in the objectivity of olfactometry studies by placing the carrier of an odorous substance in the airway of a rhinomanometer, as well as procedures for determining the energy characteristics of respiration. With the objectification of olfactometry studies, it is possible to vary such indicators as the type and concentration of an odoriferous substance, as well as the pneumatic power of respiration and the time of manifestation of sensitivity to the odorivector. the proposed method satisfies these requirements, since it takes into account the rhinomanometric characteristics of respiration under the action of an odorous substance. Taking into account that for typical diameters of the venturi flowmeters for rhinomanometric measurements in the range from 6 to 9 mm and corresponding to the pressure loss coefficient in the range 1.8 to 0.2 the total area of the inlet air holes of the odorivector nozzle should be at least 400–600 mm2, typical airflow velocities were calculated during the olfactometric study. Calculations of the intensity of evaporation of odorivectors as a function of the area of air openings in a odorivector nozzle on a rhinomanometer of the TNDA-PRH type were made. The graphs of the dependence of the intensity of evaporation of odoriferous substances on the area of the air holes of the odorivector nozzle were determined. It was found that the greatest intensity of evaporation for all odorivectors corresponds to the smallest area of the air holes of the odorivector attachment and the greatest air flow |
