Diseases of the cardiovascular system are one major causes death worldwide. These diseases could be quickly detected by changes in sound created action heart. This dynamic auscultations need extensive professional knowledge and emphasis on listening skills. There is also an unmet requirement for a compact cardiac condition early warning device. In this paper, we propose prototype digital stetho...

Objectives: Human lung sounds are important indicators of underlying lung pathology. The prime objective of this work is to classify normal and adventitious lung sounds in paediatric population using spectral features and artificial neural networks. Material and Method: 3M Littmann 3200 electronic stethoscope was used to record the lung sounds. After pre-processing ten spectral features were ex...

A medical instrument for acquisition and analysis of phono-cardiac signals is described in the paper. The proposed system is based on an electronic stethoscope with enhanced performances in environmental noise reduction, achieved by means of two microphones whose signals are combined by an adaptive algorithm. A software tool able to reproduce, visualize and analyze cardiac sounds completes the ...

This study aimed to investigate the effect of stethoscope position and contact pressure on auscultatory blood pressure (BP) measurement. Thirty healthy subjects were studied. Two identical stethoscopes (one under the cuff, the other outside the cuff) were used to simultaneously and digitally record 2 channels of Korotkoff sounds during linear cuff pressure deflation. For each subject, 3 measure...

Methods Following a standardized physical exam using sterile gloves and a sterile stethoscope, bacterial contamination of the following regions were assessed using contact plates: stethoscope diaphragm, stethoscope tube, fingertips, thenar region, hypothenar region and back of physician’s dominant hand. Total aerobic colony count (ACC) were determined on digital photographs using a counting tool.

DEVELOPMENT OF IONIC POLYMER METALIC COMPOSITES AS SENSORS By: David Griffiths Ionomeric polymer transducers (IPTs) are an exciting new class of smart materials that can serve a dual purpose in engineering or biomedical applications as sensors or actuators. Most commonly they are used for mechanical actuation, as they have the ability to generate large bending strai...

More than 370,000 Americans die every year from coronary artery disease (CAD). Early detection and treatment are crucial to reducing this number. Current diagnostic and disease-monitoring methods are invasive, costly, and time-consuming. Using an electronic stethoscope and spectral and nonlinear dynamics analysis of the recorded heart sound, we investigated the acoustic signature of CAD in subj...

Objective: To compare mean endotracheal tube cuff pressures generated using two inflation methods;just-Seal versus Stethoscope-Guided in patients undergoing elective surgery under general Anaesthesia.
 Study Design: Quasi-experimental study.
 Place and Duration of Study: Anesthesia Department, Combined Military Hospital, Rawalpindi Pakistan, from Jan to Jul 2021.
 Methodology: A ...

The stethoscope is currently at the crossroads. For two centuries now, the stethoscope has been a central part of examining the thorax. Nevertheless, this omnipresent tool of the medical profession (‘conversation piece’) is at the heart of the debate over how diagnostic medicine should be practised. At the moment, there are many divergent views on the value of using the stethoscope as a primary...

INTRODUCTION Oropharyngeal dysphagia is a highly prevalent comorbidity in neurological patients and presents a serious health threat, which may lead to outcomes of aspiration pneumonia, ranging from hospitalization to death. This assessment proposes a non-invasive, acoustic-based method to differentiate between individuals with and without signals of penetration and aspiration. OBJECTIVE This...
