A Wearable Stethoscope for Long-Term Ambulatory Respiratory Health Monitoring

Sensors, 2020
Lung sounds acquired by stethoscopes are extensively used in diagnosing and differentiating respiratory diseases. Although an extensive know-how has been built to interpret these sounds and identify diseases associated with certain patterns, its ...

Cerebrovascular pulsatility following long duration spaceflight is associated with changes in pulse pressure and carotid artery stiffness

Experimental Physiology, EarlyView.
Abstract Central artery stiffening increases the haemodynamic pulsations transmitted downstream towards target organs, including the brain. While recent evidence suggests that long duration spaceflight is associated with reduced common carotid artery (CCA) distensibility, cerebrovascular pulsatility has not been extensively characterized in astronauts.

Digital Stethoscope as an Innovative Tool on the Teaching of Auscultatory Skills

Arquivos Brasileiros de Cardiologia, 2013
Physical cardiovascular examination, particularly cardiac auscultation, is one of the most difficult clinical skills for students during their medical training. Studies suggest that the use of technologies such as digital stethoscope increase the accuracy of clinical examination, however, its impact on the teaching of cardiac auscultation for ...

Echocardiographic Findings in Small‐Breed Dogs With Myxomatous Mitral Valve Disease and the Severity of Mitral Regurgitation, Heart Size and Clinical Signs Myxomatous Mitral Valve Disease in Dogs

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Myxomatous mitral valve disease (MMVD) is the most common acquired cardiac disorder in small‐breed dogs and is characterized by progressive mitral regurgitation that can lead to cardiac enlargement and clinical signs of heart failure. Accurate assessment of structural and hemodynamic changes using two‐dimensional, M‐mode and Doppler echocardiography is

The Evolving Stethoscope: Insights Derived from Studying Phonocardiography in Trainees

Sensors
Phonocardiography (PCG) is used as an adjunct to teach cardiac auscultation and is now a function of PCG-capable stethoscopes (PCS). To evaluate the efficacy of PCG and PCS, the authors investigated the impact of providing PCG data and PCSs on how ...

Effect of Intranasal Midazolam–Butorphanol Premedication on Sevoflurane Anaesthesia in Traumatised Buzzards (Buteo spp.)

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Intranasal midazolam–butorphanol premedication in traumatised buzzards (Buteo spp.) aims to provide safer sedation by minimising mask induction stress. This method significantly reduces sevoflurane requirements while maintaining stable cardiopulmonary parameters. It is a safe and practical alternative that enhances patient welfare and induction quality.
