METHOD OF DIAGNOSTICS OF COLD-INDUCED BRONCHIAL ASTHMA Russian patent published in 2009 - IPC A61B5/08 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely, to pulmonology and can be recommended for diagnostics of cold-induced bronchial asthma. Sprographic indices of MVR₇₅ before and after forced inspiration and expiration of cooled air through mouth at temperature -20°C, containing 5% carbon dioxide, are examined. Spirographic indices of MVR₇₅ are re-measured after 30-minute walk in the open air at temperature (-20°C) -(-25°C). Calculation of discriminant function d=0.82×MVR₇₅, is performed and if d does not exceed value of 13.2 exacerbation of cold-induced bronchial asthma is diagnosed. Method increases accuracy of cold-induced bronchial asthma diagnostics.

EFFECT: increase of accuracy of cold-induced bronchial asthma diagnostics.
