MIT Automated Auscultation System
At every annual exam, the primary care physician uses a stethoscope to listen for cardiac abnormalities. This approach is non-invasive, inexpensive, and fast. It is also highly unreliable. Over 80% of the people referred to cardiologists as suffering from the most commonly diagnosed condition, …

Classification of Auscultation Sounds Using a Smart System
… further of the acceptance of electronic auscultations. As telemedicine grows, this will also drive up the demands for such devices. Other holistic measures that are used in medicine will likely also be be developed as the landscape of healthtech changes what is possible.

Automated auscultation : using acoustic features to diagnose mitral valve prolapse
… muscle and valves. This process, termed cardiac auscultation, is the primary means of diagnosing cardiac disorders, the most common of which is Mitral Valve Prolapse (MVP). Yet, the practice of auscultation is highly fallible with reports of more than 80% of MVP referrals to cardiologists being …

Computer-assisted auscultation as a screening tool for cardiovascular disease : a cross-sectional study
Cardiac auscultation is inherently qualitative, highly subjective and requires considerable skill and experience. Computer- assisted auscultation (CAA) is an objective referral-decision support tool that aims to minimise inappropriate referrals. This study evaluated the sensitivity and specificity …

An observational study of student osteopaths' measurement of arterial blood pressure by sphygmomanometry and auscultation
The aim of this study was to observe the rate of compliance that postgraduate (4th and 5th year) osteopathy students demonstrate when applying their undergraduate blood pressure (BP) measurement training in a clinical situation. Thirty-seven volunteer postgraduate participants were watched …

Assisted auscultation : creation and visualization of high dimensional feature spaces for the detection of mitral regurgitation
Cardiac auscultation, listening to the heart using a stethoscope, often constitutes the first step in detection of common heart problems. Unfortunately, primary care physicians, who perform this initial screening, often lack the experience to correctly evaluate what they hear. False referrals are …

Lung auscultation as a predictor of lung lesions and bovine respiratory disease outcome in feed yard cattle
… reported here were to: 1) validate a thoracic auscultation scoring system by correlating ante-mortem lung sounds with post-mortem lung lesions and 2) evaluate thoracic auscultation and rectal temperature as diagnostic tools to predict case outcome in the feeder cattle treated for BRDC. First, a …

A data mining approach for acoustic diagnosis of cardiopulmonary disease
… make diagnosing a patient via stethoscope based auscultation problematic. Doctors have now turned to more advanced devices such as x-rays and computed tomography (CT) scans to make diagnoses. However, recent advances in lung sound analysis techniques allow for the auscultation to be performed …

The problem of the stethoscope: an enquiry, experimental and philosophical, into the properties of this instrument and the physics of auscultation
My interest in Stethoscopy dates back to the time when I first entered the class of Clinical Medicine. I had previously, while on war service, been interested in the propagation of sound in sea water, and finding that acoustics played so important a part in the diagnosis of pulmonary and cardiac …

Interrogating the lungs through wearable fabric electronics
… to the sounds the body makes, also known as auscultation. In this thesis, we sought to develop a lightweight, flexible, wearable fabric that can perform auscultation on the lungs. These fibers were created using the thermal drawing process that allows the fibers to perform various functions …

Development of novel optical sensing-based digital stethoscopes and deep learning-based heart sound denoising algorithms
… heart sound denoising algorithms. Cardiac auscultation is the act of listening non-invasively to the sounds of the heart. It provides insights into the mechanical activity of the heart, and the sounds produced by this activity can be recorded as a phonocardiogram (PCG) using a digital …

A Comparison of Wavelet and Simplicity-Based Heart Sound and Murmur Segmentation Methods
… enough to be carried around by a clinician. Auscultation with a stethoscope requires considerable skill and experience, but the introduction of digital stethoscopes allows for the automation of this task. Auscultation waveform segmentation, which is the process of determining the boundaries …

Artificial Intelligence and Signal Analysis for COPD Classification: Detecting and Understanding of Respiratory Disease Severities
… to enhance the diagnostic potential of pulmonary auscultation audio for automatic COPD identification and severity assessment. The research comprises three main parts: 1) developing algorithms for compression and reconstruction of auscultation signals whilst the diagnostic integrity is preserved, …

A MULTIMODAL CLINICAL AND DIAGNOSTIC APPROACH TO BOVINE RESPIRATORY DISEASE COMPLEX (BRDC) IN DAIRY CALVES
… under field conditions; 3) To standardize lung auscultation in order to increase its diagnostic accuracy; 4) To analyze hemogas-analytical and metabolic changes during BRDC by correlating them with clinical and ultrasonographic diagnosis. For this purpose, pre-weaning Italian Friesian calves …

Survey of Knowledge of Fifty Registered Professional Nurses Regarding Selected Factors of Indirect Blood Pressure Measurement
… of measurement the nurses used, other than auscultation, was the palpatory method. In general, most nurses could not correctly identify a systolic reading nor correctly record a reading containing variables. Only one half of the fifty respondents identified the diastolic reading adequately. …

Development of a Software Application to Extract the Features of Normal Respiratory Sounds from the Lungs and the Trachea
Auscultation has been widely regarded as one of the most important noninvasive diagnostic tools for clinical diagnosis of the respiratory tract. The purpose of this thesis was to develop a software application capable of extracting the key features of respiratory sound signals from the lungs and …

Evaluation of positive expiratory pressure (PEP) devices as an adjunct to cardio-respiratory physiotherapy in patients following open abdominal surgery
… where changes from pre-operative findings of auscultation; temperature, X-ray and sputum are evaluated post-operatively and recorded using the Adapted Abdominal Physiotherapy Outcomes Data Sheet (A-APODS). Results: A total of 19 participants were enrolled in the study, n=11 (CG) and n=8 (IG), …
