Objective. To determine the efficiency of diagnostics of the clinical syndrome of bronchial obstruction with WheezeScan detector in children, to assess the sensitivity and specificity of this method. Electronic medical devices used for registration and analysis of breath sounds can help to diagnose different syndromes in pediatric pulmonology. Materials and methods. The study involved 15 children aged 1 to 17 years, who were hospitalized to Pulmonology Unit of the Regional Childrens Clinical Hospital. The children were divided into two groups depending on the presence or absence of wheezes in auscultation. The detector WheezeScan HWZ-1000T-E (Omron) was used to study the presence of wheezes. The control group included children without any objective signs of bronchial obstruction. Results. It was detected while examining children that in auscultation 20 % (n=3) of children had dry wheezes, and in detector diagnostics the result was positive in 100 % of cases. In auscultation, 80 % (n=12) of children did not show clinically marked bronchial obstruction syndrome, the result of WheezeScan detector was 73 % (n=11). Diagnostic sensitivity and specificity was 100 %. Conclusions. Screening diagnostics of bronchial obstruction syndrome in children by means of electronic detector of wheezing is effective and can be applied for ambulatory patients of different ages in a pediatric hospital unit.
