A Wireless Electronic Esophageal Stethoscope for Continuous Monitoring of Cardiovascular and Respiratory Systems during Anaesthesia
Background: The basic requirements for monitoring anesthetized patients during surgery are assessing cardiac and respiratory function. Esophageal stethoscopes have been developed for this purpose, but these devices may not provide clear heart and lung sound due to existence of various noises in operating rooms. In addition, the stethoscope is not applicable for continues monitoring, and it is u...
متن کاملPleural effusion and cardiac displacement in a heifer: a case report
A 16-month-old Holstein heifer with a history of anorexia and respiratory distress was referred to the Veterinary Research and Teaching Hospital of Tehran University. Heart and lung sounds were inaudible on the left side but greatly increased on the right side. On electrocardiography (ECG), decreased amplitudes of ECG parameters were observed. Ultrasonography results revealed a pleural effusion...

متن کاملRespiratory health screening using pulmonary function tests and lung sound analysis.
Lung sounds (LS) analysis is a potential source of additional objective, noninvasive and quantitative information on the status of the pulmonary system. We have examined the hypothesis that the addition of lung sounds analysis to spirometry increases the sensitivity of objective population screening, as compared to the use of spirometry alone. Questionnaires, spirometry and lung sounds were obt...
متن کاملRecursive Least Squares Adaptive Noise Cancellation Filtering for Heart Sound Reduction in Lung Sounds Recordings
It is rarely possible to obtain recordings of lung sounds that are 100% free of contaminating sounds from nonrespiratory sources, such as the heart. Depending on pulmonary airflow, sensor location, and individual physiology, heart sounds may obscure lung sounds in both time and frequency domains, and thus pose a challenge for development of semi-automated diagnostic techniques. In this study, r...
متن کاملAuscultation of the lung: past lessons, future possibilities.
Review of the history of auscultation of the lung reveals few scientific investigations. The majority of these have led to inconclusive results. The mechanism of production of normal breath sounds remains uncertain. Hypotheses for the generation of adventitious sounds are unproven. Advances in instrumentation for lung sound recording and analysis have provided little of clinical value. There ha...
