摘要

肺部感染和肺部疾病很常见,可能会致命。因此,预防肺病比治疗肺病更重要。与城市地区相比,农村地区的专科医生较少。因此,有必要开发一些方法,使偏远地区的人们可以由可能很远的专家医生监测。本文提出了一种通过分析听诊获得的肺音来初步检测肺部感染的方法。为了分析肺音,计算并绘制FFT。一些预先录制的肺部声音也有助于分析。根据上述计算中观察到的变化,将肺音分类为正常或非正常。这些数据可以通过GSM/3G无线发送到医院的服务器,专科医生可以进一步分析以确认肺部感染。

Monitoring and analysis of lung sounds for the diagnosis of lung abnormalities
Lung infections and lung diseases are common and can be potentially deadly. Hence preventing lung diseases is more mandatory than curing them. Specialist doctors are less available in rural areas compared to urban areas. Thus it has become necessary to develop some method by which people in remote areas can be monitored by specialist doctors who might be far away. This paper proposes a method for preliminary detection of lung infections by analyzing lung sounds obtained by auscultation. To analyze the lung sounds, FFT was calculated and plotted. A number of pre-recorded lung sounds aided the analysis as well. Classification of lung sounds, as normal or adventitious, was done based on the variations observed in the above calculations. This data can be sent wirelessly via GSM/3G to the server in hospital where a specialist doctor can further analyze it for confirmation on lung infection.
