A study of contemporary book reviews and other notices enables us to trace the reception of the stethoscope and Laënnec's book between 1816 and 1826. It is quite clear from these that the stethoscope was welcomed with enthusiasm by most people who saw it as the first major diagnostic tool medicine had ever had. Laënnec's book was recognised as being the most important, interesting, accurate, an...

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...

Heart diseases caused by the heart and blood vessels disorders are world’s largest killers. Hence early detection and monitoring of heart abnormalities is essential for diagnosis and effective treatment of heart diseases. This project aims to develop a low cost portable digital stethoscope. The primary function of this system is to work exactly like a normal stethoscope, but having an added adv...

T he stethoscope has been so widely used by clinicians in the diagnosis and management of patients' illnesses that it has virtually become a symbol of the medical profession. Indeed, as pointed out by Reiser in Scientific American, the invention of the stethoscope by Laënnec revolutionized medicine, changing it from an art to a science [1]. Another revolution is now going on. Auscultation of th...

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...

Heart diseases are among the most important causes of mortality in the world, especially in industrial countries. Using heart sounds and the features extracted from them are among the non-aggressive diagnosis and prognosis methods for heart diseases. In this study, the time-scale, Cepstral, frequency, temporal and turbulence features are saved and extracted from the heart sounds, and then they ...

Vigilance is the motto for the American Society of Anesthesiologists. Vigilance over the sedated pediatric dental patient is essential for safe and successful treatment. Especially important is vigilance over the patient’s airway. If airway compromise can be quickly detected and corrected, then the likelihood of the patient experiencing a decrease in oxygen saturation will be low. Hypoxia cause...

OBJECTIVE Bowel dysfunction remains a major problem in neonates. Traditional auscultation of bowel sounds as a diagnostic aid in neonatal gastrointestinal complications is limited by skill and inability to document and reassess. Consequently, we built a unique prototype to investigate the feasibility of an electronic monitoring system for continuous assessment of bowel sounds. METHOD We attai...
