Background. Searching the new diagnostic methods for respiratory diseases remains one of the most important tasks of modern medicine.
Methods. 36 healthy men and 108 men with community-acquired pneumonia at the age of 18 to 80 years have been examined. All inflammatory epicenters were located in the lower lobes, often from the right. Roentgenologically the pneumonia focus has been described as the lung tissue’s infiltration in 100% of cases.
Results. There were developed the spectral criteria for the acoustic diagnosis of a core in patients with pneumonia determined by standardized phonorespirography by quiet breathing airflow. According to the examined sample there was reached the maximum specificity for the healthy group – 80.5%, the maximum sensitivity for detection of the epicenters – 83.3%. Consequently, sensitivity of the phonorespirography is much higher than the one of subjective auscultation that presents 45%.
Conclusions. The achieved values of sensitivity and specificity of phonorespirography of quiet breathing allow to recommend this method for inter-roentgen monitoring the focal lesion in the lung in outpatient and inpatient settings.
