Xinhua News Agency, Beijing, May 31 (Reporter Wang Bingyang) On May 31 World No Tobacco Day, World Health Organization data shows that the global tobacco epidemic kills nearly 6 million people every year. Experts said that there is sufficient evidence that smoking is closely related to lung cancer and other diseases. In order to effectively prevent lung diseases, digital auscultation can be used for scientific monitoring and early diagnosis.

  "We used digital auscultation equipment to study more than 1,000 healthy smokers. The results show that the doctor ’s auscultation conclusions are completely normal, but after applying computer analysis, the physical indicators of lung sounds of smokers have changed significantly, which means that there are many types of digital auscultation. The lung sound index can sensitively reflect the early damage to the lungs of smokers. "Professor Liu Guoliang, chief physician of the Respiratory Center of China-Japan Friendship Hospital and chairman of the Clinical Auscultation Expert Committee of the National Telemedicine and Internet Medical Center, said that the acoustic properties of lung auscultation sounds should be changed For early events of lung damage caused by smoking, lung auscultation sound analysis can be used as a monitoring indicator for smoking early lung damage. "That is to say, the application of digital auscultation technology can detect the early changes of lung sounds of smokers, and early intervention diagnosis can effectively prevent and control the occurrence of lung diseases."

  The digital auscultation technology of this project is the transformation of the research results of the major project of the prevention and control of major non-communicable diseases in the national key research and development plan undertaken by the China-Japan Friendship Hospital 2016 "Project on the Quality Control Strategy of Graded Prevention of COPD Stability" (2016YFC1304602) . The digital auscultation technology uses acoustic principles to collect human heart sounds, lung sounds, bowel sounds, etc. through a digital stethoscope and upload them to the digital auscultation platform. Doctors can quickly and scientifically make medical judgments and disease diagnoses based on patient objective information.

  Digital auscultation also provides technical support for remote graded diagnosis and treatment and remote first diagnosis. Liu Guoliang introduced that the current digital auscultation equipment can realize the effect of actual clinical auscultation through real-time transmission through the network, and can realize one person collection and multiple people auscultation at the same time. In addition to audio file collection, the platform can also provide lung health feature spectrum charts, waveform charts, 3D spectrum charts, diagnostic index tables, diagnostic results, and other graphical visualizations of respiratory health for doctors to diagnose in real time. Through the digital auscultation service platform, remote real-time and high-definition digital auscultation can also be achieved to meet the requirements of remote medical auscultation on the spot.

  "With the popularization and application of digital auscultation technology, digital auscultation technology services will effectively promote the field implementation of telemedicine and the implementation of chronic diseases and health management, and smart medical and other related projects." Liu Guoliang said.
