Expert: Digital stethoscope technology can monitor early lung lesions

June 1st, World Health Organization data show that the global tobacco epidemic kills nearly 6 million people each yearExperts say there is ample evidence that smoking is closely linked to diseases such as lung cancer, and that in order to prevent lung lesions effectively, scientific monitoring can now be carried out through digital hearings for early diagnosis
"We used digital listening equipment to study more than 1,000 healthy smokers, and the results showed that the doctor's listening conclusions were completely normal, but after computer analysis, there was a significant change in the physical index of the smoker's lung tone, which means that digital listening to a variety of lung tone indicators can sensitively reflect the early injury of the smoker's lungsProfessor Liu Guoliang, director of theRespiratory Center at the China-Japan FriendshipHospital and chairman of the National Center of Clinical Hearing Experts at the National Telemedicine and Internet Medical Center, said that changes in the acoustic nature of lung listening should be an early event of lung damage caused by smoking, and lung listening analysis could be used as a monitoring indicator for early lung damage"In other words, the use of digital listening technology can detect early changes in the sound of the smoker's lung, early intervention diagnosis, can effectively prevent and control the occurrence of lungdisease." "
the project's digital listening technology is from the China-Japan Friendship Hospital to undertake the national key research and development plan of major noncommunicable diseases prevention and control key 2016 project "slow lung stabilization period graded prevention quality control strategy study" (2016YFC1304602) research resultsThe digital stethoscope technology uses the acoustic principle, through digital stethoscope to collect the human heart tone, lung tone, intestinal sound, etc., uploaded to the digital stethoscope platform, doctors combined with patient objective information can quickly and scientifically make medical judgment and disease diagnosisDigital stethoscopes also provide technical support for remote graded consultations and remote first consultationsLiu Guoliang introduced that the current digital listening equipment can be transmitted through the network real-time to achieve the effect of actual clinical hearing, and can achieve one person collection, many people at the same timeIn addition to audio file acquisition, the platform can also provide pulmonary phonetic feature syllation spectrum map, wavemap, 3D spectrum map, diagnostic index table, diagnostic results and other respiratoryand graphical visualization files for doctors to diagnose in real time Through the digital listening service platform, remote real-time high-definition digital listening can also be realized, to meet the requirements of telemedicine listening field
"With the popularization and application of digital listening technology, digital listening technology services will vigorously promote the fieldprocess of telemedicine and the implementation of related projects such as chronic disease and health management, as well as smart medicine Liu Guoliang said
