METHOD OF DIAGNOSING RESPIRATORY FUNCTION BY MEANS OF IMPEDANCE SPIROGRAPHY AND COMPUTER APPLIANCE "BIA-lab Spiro" FOR ITS REALISATION Russian patent published in 2013 - IPC A61B5/08 A61B5/87 A61B5/91 

FIELD: medicine.

SUBSTANCE: invention relates to medicine and medical equipment. Bipolar method of poly-frequency impedancemetry . Module value of impedance (Z) and phase angle (φ) at frequencies 20, 98, 1000, 5000, 10000, and 20000 Hz of alternating electric current of low power during inhalation of 0.9% of sodium chloride solution. In the process of measurement the first electrode is installed into mouthpiece of ultrasound nebuliser, the second is placed on chest skin or in the region of examination, or joining electrodes, installed on symmetrical sections of chest. If deviations of Z and/or φ values are less than 5 or more than 95 percentiles from the normal values, impairment of respiratory function is diagnosed. To carry out diagnostics computer appliance, which contains measurement unit, mouthpiece, nebuliser inhalator, as well as electrodes, one of which is installed on patient's chest, the other is installed in mouthpiece of ultrasound nebuliser inhalator.

EFFECT: invention makes it possible to increase reliability of respiratory function diagnostics.
