Heart sounds during fluothane anaesthesia [PDF]
Canadian Anaesthetists’ Society Journal, 1957 1. The usual predominance of the intensity of the first heart sound over that of the second heart sound frequently may be reversed during anaesthesia produced by Fluothane, the intensity of the second heart sound becoming greater relative to the first heart sound. 2. Four electroencephalographic patterns were discerned during anaesthesia

Radar-Based Heart Sound Detection [PDF]
Scientific Reports, 2018 AbstractThis paper introduces heart sound detection by radar systems, which enables touch-free and continuous monitoring of heart sounds. The proposed measurement principle entails two enhancements in modern vital sign monitoring. First, common touch-based auscultation with a phonocardiograph can be simplified by using biomedical radar systems. Second,

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Internal Medicine, 2019 A 79-year-old man with dilated cardiomyopathy and severe functional mitral regurgitation presented with general fatigue and dyspnea. Auscultation revealed a systolic regurgitant murmur with a minimized second heart sound due to a low output. On the other hand, the third heart sound was ultimately enhanced, being visible and palpable as a pulsatile ...
