METHOD FOR PREDICTING THE DEGREE OF FIBRILLATION ARRHYTHMIA PAROXYSMS IN PATIENTS WITH ACCOMPANYING OBSTRUCTIVE PULMONARY DISEASES Russian patent published in 2008 - IPC A61B5/00 

FIELD: medicine, cardiology.

SUBSTANCE: it is necessary to detect the degree of heart failure during a paroxysm of fibrillation arrhythmia (FA) that should be verified by the value of increased transcutaneous partial pressure of tissue oxygen in the course of combined application of 30% oxygen inhalation through a mask for 3 min and monitoring transcutaneous partial pressure of oxygen with the help of an electrode of Clarc type. Moreover, one should study transcutaneous oxygen mode of tissues during paroxysm of fibrillation arrhythmia initially and during inhalation with 30% oxygen in the following mode: one should apply an electrode onto forearm's skin to carry out polarography and heat it from 37 up to 45°C for a period of increasing pO2 value till achieving its stabilization, fix the value of pO2 transcutaneous parameter followed by inhalation of 30% oxygen by a patient for 3 min, fix repeated transcutaneous pO2 value, calculate % against age standard of transcutaneous pO2 measured after oxygen inhalation, moreover, at values of transcutaneous pO2 being near to age standard FA paroxysm should be considered as hemodynamically valuable, and one should evaluate the degree of hemodynamically valuable FA paroxysm according to the following criteria: severe degree of FA paroxysm: initial transcutaneous pO2 up to 45-49 mm mercury column, and after oxygen test - 50 mm mercury column, not more, average degree of FA paroxysm: initial transcutaneous pO2 up to 50-54 mm mercury column, and after oxygen test - 60 mm mercury column, not more, light degree of FA paroxysm: initial transcutaneous pO2 being above 55 mm mercury column, and after oxygen test - above 60 mm mercury column. The innovation enables to increase the efficiency of instrumental methods for predicting the degree of FA paroxysms by 40-60%.

EFFECT: higher accuracy of diagnostics.
