Sensitivity and specificity of the method of acoustic diagnosis of pneumonia using the acoustic monitoring device Trembita-Corona
Background. Diagnosis of pneumonia is difficult and requires a comprehensive examination. Respiratory acoustics is currently a promising diagnostic method. The purpose was to evaluate the possibility of pneumonia detection by the average signal power, frequency and amplitude of the acoustic signal using the Trembita-Corona acoustic monitoring device. Materials and methods. Onу hundred and ninety-three children aged from 1 month to 18 years were examined. The children were divided into two groups: group I — 98 patients with community-acquired pneumonia, group II — 95 healthy children. All children were examined using the Trembita-Corona acoustic monitoring device. Results. The sensitivity of the method for detecting pneumonia using the acoustic monitoring device Trembita-Corona according to the average signal power in the 4th, 5th and 6th octaves is from 90.8 to 99 %, and the specificity is from 87.4 to 100 %. The sensitivity of the method for detecting pneumonia using the acoustic monitoring device Trembita-Corona according to the frequency of the acoustic signal in the 3rd and 5th octaves is more than 60 %, and the specificity is more than 63 % in the 3rd octave and 100 % in the 5th octave, respectively. The sensitivity of the method for detecting pneumonia using the acoustic monitoring device Trembita-Corona according to the amplitude of the acoustic signal in the 4th, 5th and 6th octaves is 88.9, 99.9 and 86.9 %, respectively, and the specificity is 100 % in the 4th and 5th octaves and 87.4 % in the 6th octave. Conclusions. The acoustic monitoring device Trembita-Corona demonstrates high specificity, sensitivity and positive predictive value and negative predictive value at given prevalence..
