BACKGROUND AND AIM Two hundred years ago Laennec, a young French physician discovered the stethoscope, in order to improve the lung auscultation. The stethoscope became the emblematic appendix of the physicians. Nurses use it also to monitor patients and medical students are proud to use it. We critically review the significance of the stethoscope 200 years after its discovery. METHODS Pertin...

BACKGROUND To determine whether the use of an electronic, sensor based stethoscope affects the cardiac auscultation skills of undergraduate medical students. METHODS Forty eight third year medical students were randomized to use either an electronic stethoscope, or a conventional acoustic stethoscope during clinical auscultation training. After a training period of four months, cardiac auscul...

The practice of cardiac auscultation is a critical tool used by physicians to detect alterations in the cardiovascular system. A case of both left and right sided endocarditis initially detected by electronic auscultation in a woman with a history of injection drug use is described. The electronic stethoscope, with the ability to amplify heart sounds, established the presence of both a systolic...

Respiratory support is a lifesaving therapy, but it also augments the risk of contracting complications attributable to the endotracheal tube, positive pressure ventilation, or sedation. It is essential to develop strategies to optimize respiratory support in order to minimize the development of these complications. Management of such patients is difficult because the underlying pathologies are...

Developing countries like India, where doctor to patient ratio is around 1:1700, as large number of population lives in villages and remotely located area. Health check-up of such a large population is very challenging for their government due to less number of qualified doctors, highly qualified doctor refuges to work in villages and remotely placed areas. This paper proposes a new idea by whi...

We have developed an Internet-based tool for remote realtime auscultation. The device was based on a commercially available electronic stethoscope and a PC which digitized and transmitted the signals. A voice and video channel were also available. The remote auscultation tool was evaluated between two sites in Sweden separated by a distance of 500 km. A doctor at one of the sites performed card...

In this paper, an electronic stethoscope is designed based on a bionic Micro-Electro-Mechanical System (MEMS) sound-sensitive sensor. Inspired by the strong sound reflection effect of water-air interface, double-sided diaphragm MEMS (DMES) encapsulated novel packaging proposed. The packaging’s superiority verified comparing single (SMES) with DMES. frequency clinical heart signal mostly in rang...
