Abilities of combined bronchophonography in the detection of pneumonia
Abstract
The method of combined bronchophonography (BPG), which provides sound selection of air and structural voice conduction to a chest wall, was applied in 74 patients with bacterial pneumonia. A control group involved 55 healthy subjects. All the persons underwent the BPG 2 to 3 times at intervals. The results were compared with clinical and radiological findings. A pneumonic focus situated corresponding to radiological and physical data was detected in 69 pneumonia patients (the sensitivity was 0.93). The acoustic focus revealed had a reinforced structural sound conduction and a weaken air sound conduction, was placed asymmetrically and disappeared over time according to the patient’s recovering. False positive results were obtained in 3 controls (the specificity was 0.94). Therefore, the BPG can be used as an additional objective method for the diagnostics of pneumonia and monitoring the dynamics of a pneumonic focus.
