METHOD TO DETERMINE FUNCTIONAL STATE OF BRONCHORECEPTORY APPARATUS Russian patent published in 1997 - IPC

FIELD: medicine, pulmonology. SUBSTANCE: method deals with body plethysmography to study the factors of respiratory biomechanics. Then the degree of bronchoobstructive syndrome is calculated according to following formula: , where is the ratio of efficient expiration resistance to efficient inhalation resistance. is the ratio of efficient expiration resistance to respiratory tract resistance ability determined according to laminar constituent. is a relative factor of forced expiration volume per a second. Slgtot is a specific bronchial conductivity, at the value above 1 the presence of pathology in bronchorespiratory system is revealed. Then successive cold impact, physical load, postload, inhalation with histamine and salbuthamol solution is conducted followed by studying the factors of respiratory biomechanics. Positive reaction is determined at 20% increase of the value against the next initial level that characterizes the presence of increased nonspecific bronchial sensitivity. EFFECT: higher accuracy of the method, higher efficiency in revealing preclinical type of pathology.
