title: [Examination of the temperature stabilization process in the upper airways using a miniaturized electronic thermometer].
abstract: Diagnostic and treatment procedures in laryngology demand the knowledge on physiological processes taking place in nasal cavities in the course of breathing. It is of special importance in treatment with pharmacologic agents exerting an influence on nasal blood vessels and in nasal structures operations. The paper presents electronic thermometer which was specially designed for measurements in human higher airways. The system is set of flexible measurement head with miniature thermistor and microprocessor system connected to the personal computer fit out database application for collect and visualization measurement data. The device is safe for medical doctor and patient as well. With patient point of view, the measurements can be done easily and comfortably. The system allows recording dynamic changes of air temperature in upper airways and recalculates average inspired and expired air temperatures. The paper presents also initial results obtained in group of 15 healthy volunteers and 3 with tracheotomy It was made an estimation nasal ability to heating inspired air in particular places of nasal cavity and determined air temperature in nasal cavity outlet.
