Lung Sounds and the Stethoscope — a Lung Sounds Primer

Lung Sounds

Digital Stethoscope for Heart Sounds

The stethoscope has been used for many years, and has been very effective to diagnose certain cardiologic and pulmonologic sounds. For many years healthcare professionals would listen quietly to patients internal organs so they could diagnose from specific sounds of such internal organs. The objective is to develop a Peripheral Interface Controller based digital Stethoscope to capture the heart...

Monitoring and analysis of lung sounds remotely

Visual and auditory analysis of respiratory sound signals promises improved detection of certain types of lung diseases. LabVIEW software was used to design a system that monitors the respiratory activity of the patient. The program developed calculates the respiratory rate, displays the time expanded waveform of the lung sound, and computes the fast Fourier transform and short-time Fourier tra...

Stethoscope for Monitoring Neonatal Abdominal Sounds

This research involves the development of a custom electronic stethoscope system for monitoring abdominal, or so-called bowel, sounds in premature infants. Possible causes of bowel dysfunction in premature infants include bowel obstruction, functional or anatomic, which may be reflected as an abnormality or lack of peristalsis. Such dysfunction is problematic to feeding the infant. This perista...
